Ignition Weapons - Tower of God: New World

What are Ignition Weapons?

Ignition Weapons are pieces of Equipment that you can give to your units to improve their stats.
Every unit has 5 slots where you can equip an Ignition Weapon piece.

Equipping 2 or 4 pieces of the same Ignition Weapon will give additional set effects.
You can see all currently available IW sets at this link.

Every IW piece can be one of three ranks: C, B and A.
Anything lower than A rank should NOT be upgraded and is basically used to level up other pieces or dismantled, more info in the next sections.

Every IW piece has a Main Stat and up to 4 Substats.
The Main Stat changes based on the slot.
Slots 1 has ATK%, Slot 2 has DEF% and Slot 3 has HP%.
Slot 4 and 5 can roll one of five stats, refer to the list below:

Slot 4

Magic Resistance

Effect Resistance

Effect Hit

Critical DMG Increase

Critical DMG Reduction

Slot 5

Physical Resistance

Physical Pierce

Magic Pierce

Critical Hit Rate

Critical Hit Resistance

Ignition Weapons Slot Numbers

Ignition Weapon with 3 starting Substats

Ignition Weapon with 4 starting Substats

A Rank IW Pieces can roll with 3 or 4 starting substats.
Because of the Reroll system that was recently introduced, IW pieces that start with 3 rolls are almost useless and can be destroyed.

Note: Slot 4 and 5 not only can roll different Main Stats, but they also have a lower chance of dropping, making getting a piece with the stats you want a lot harder.

The same stat cannot appear twice on a single piece, so if you have a piece with Magic Pierce Main Stat you cannot roll that in the substats.

We are going to cover upgrades and Substat high/low rolls in the Upgrade section of the guide.

To give an IW to a unit, you must upgrade their Exclusive Equipment to +20 and then spend 100 Soul Crystals to unlock the Carrier.

How do you obtain Ignition Weapons?

Ignition Weapons can be obtained from the Secret Floor, content that is unlocked upon reaching F18-20.
There are different Secret Floors, and each of them will drop one of the two featured Ignition Weapons when you successfully clear it.

You have 3 free clears every day, and for any additional clear you will need a item called "Master Key".

Each week, one of the Secret Floors will have a Rate Up event that will increase the drop rate of A rank IW pieces.
Normally, you obtain A rank pieces with a 20% rate, but during the event the rate goes up to 30%.

The Secret Floor also gives Weekly rewards if you can clear any of them with 50 Restraint Points.
Restraint Points are just debuffs for your units or buffs for the enemies that you can select for additional rewards.
I would NOT recommend selecting the last debuff "Blocks all allies's Special Moves".

Note: Higher restraints DO NOT equal higher rewards, only do 50 Restraints for the Weekly rewards and then clear them at 8 Restraints for the Auto Clear function.

Secret Floor - Rate Up Sundance/Sela

Fusion

If you go in the Equipment tab of any Unit you will see a Fusion button in the top right corner.
This feature will give you the option to fuse 3 IW pieces you don't want/need into a different IW piece of your choice.

I see this feature as being more useful early on, but will quickly become more annoying than helpful.

Note: Considering how rare Slot 4 and Slot 5 pieces are, it is recommended that you ONLY fuse for one of these two slots.

How to Upgrade Ignition Weapons?

Rank A IW pieces start at +0 and can be upgraded up to +20.
Every 4 levels a random substat will receive an upgrade, which means an additional roll.
If the piece started with 3 Substats, at +4 they will get the 4th stat, which means the total number of upgrades will be 4 instead of 5.

A substat can roll 1 of 4 possible values, shown in the table below:

Stat	Low Roll	Mid-Low Roll	Mid-High Roll	High Roll	Theoretical Max at +20
HP%, ATK%, DEF%	1.0%	1.5%	2.0%	2.5%	15%
Critical Hit, Pierce, Resistance	1.5%	2.5%	3.5%	4.5%	27%
ACC, EVA, Effect Hit, Effect Resistance	3	6	9	12	72

Main Stats on the other hand have fixed values, you can refer to the table below:

Slot	Stat	+0	+4	+8	+12	+16	+20
1	ATK%	13.8%	28.2%	42.4%	57.0%	71.4%	85.8%
2	DEF%	13.8%	28.2%	42.4%	57.0%	71.4%	85.8%
3	HP%	13.8%	28.2%	42.4%	57.0%	71.4%	85.8%
4	Critical Hit DMG Increase Critical Hit DMG Reduction Magic Resistance	8.0%	14.4%	20.8%	27.2%	33.6%	40.0%
4	Effect Hit Effect Resistance	20	60	100	140	180	220
5	Critical Hit Rate Critical Hit Resistance Physical Resistance Physical Pierce Magic Pierce	8.0%	14.4%	20.8%	27.2%	33.6%	40.0%

To enhance an IW piece you will need to feed it one of two things:

Other IW pieces

Items called Shinsu Sea Whethstones

This table shows how much EXP you get from every type of item:

Item	EXP
Common Shinsu Sea Whethstone	10
Uncommon Shinsu Sea Whethstone	1000
Rare Shinsu Sea Whethstone	10000
Ignition Weapon +0 - C Rank	1250
Ignition Weapon +0 - B Rank	2500
Ignition Weapon +0 - A Rank	3750

And this is how much EXP you need in order to reach certain levels:

Rank	+4	+8	+12	+16	+20
A	16200	45650	86050	149250	263450

Note: At first you should focus on upgrading IW sets ONLY for your carry units.
On everyone else you can simply run 4 NOT upgraded Bari pieces of any rarity, regardless of the stats.

Which stats should you look for?

The stats that you want to look for will depend on a few key factors:

Your deficit. When your Deficit is low (approx. lower than 300) Resistances will work well, but when your deficit gets higher they can be removed completely.

The Damage Scaling of the unit. Units that scale on ATK% will need Pierce and Critical Hit stats, but units that scale on Enemy Max HP should not run those.

Range of attacks. If a unit is melee they might need to build some defensive stats to stay alive, if they are ranged you could get away with a fully offensive build.

If a Unit has Debuffs or Status Effects you need to land. In that case Effect Hit will help.

The stats you get from the Archive. If your Archive has low EVA, then building EVA on IWs will be useless, but if you have an high amount of that, building EVA could be a good idea.

Keeping that in mind, I will now give you an overview of what I think are the stat priorities for different unit types.
Some units could have individual differences that will require specific stats, refer to the individual unit guide for more information.
PvP is not taken into consideration here.

Unit Type	Deficit < 300	Deficit > 300 [LOW Archive EVA]	Deficit > 300 [HIGH Archive EVA]
ATK Scaling DPS [Melee]	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, Magic/Physical Pierce, Critical Hit Damage, Critical Hit Rate, Effect Resistance, ACC Notes: Before you invest in Damage, the primary goal is to get to 99% in both Resistances so you can survive longer [Unless your DPS has good base survivability]. If you can reach this threshold with just substats, then you can run Slot 5 with the Pierce corrisponding to your unit's damage type, or Critical Hit Rate if that is something your DPS needs.	Main Stat Slot 4: Critical DMG Increase/Effect Resistance/Effect Hit Slot 5: Magic/Physical Pierce Substats: Magic/Physical Pierce, Critical DMG Increase, Critical Hit Rate, Effect Hit, Effect Resistance, ACC Notes: Here you just want to build offensive stats. If the unit is a Mage or an Assassin, you don't have to look for Critical Hit Rate, as you already have it in the Revolution subnodes. Some DPS units, like Hugo, could prefer Effect Resistance instead of Critical DMG Increase in Slot 4.	Main Stat Slot 4: Critical DMG Increase/Effect Resistance/Effect Hit Slot 5: Magic/Physical Pierce Substats: Magic/Physical Pierce, EVA, Critical DMG Increase, Critical Hit Rate, Effect Hit, Effect Resistance, ACC Notes: Aim for Pierce, double Crit and EVA on most pieces.
ATK Scaling DPS [Ranged]	Main Stat Slot 4: Critical DMG Increase Slot 5: Magic/Physical Pierce Substats: Magic/Physical Pierce, Critical DMG Increase, Critical Hit Rate, Effect Hit, Effect Resistance, ACC Notes: If the unit is a Mage or an Assassin, you don't have to look for Critical Hit Rate, as you already have it in the Revolution subnodes. Some Ranged DPS units, like Kaiser and Lightning Spear Mascheny could run Resistances instead to improve their poor survivability.	Main Stat Slot 4: Critical DMG Increase Slot 5: Magic/Physical Pierce Substats: Magic/Physical Pierce, Critical DMG Increase, Critical Hit Rate, Effect Hit, Effect Resistance, ACC Notes: Here you just want to build offensive stats. If the unit is a Mage or an Assassin, you don't have to look for Critical Hit Rate, as you already have it in the Revolution subnodes.	Main Stat Slot 4: Critical DMG Increase Slot 5: Magic/Physical Pierce Substats: Magic/Physical Pierce, EVA, Critical DMG Increase, Critical Hit Rate, Effect Hit, Effect Resistance, ACC Notes: Aim for Pierce, double Crit and EVA on most pieces.
Max HP Scaling DPS	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, Effect Resistance, Effect Hit, ACC, EVA Notes: Max HP Damage does NOT Crit and is not affected by Resistances and DEF. Just build for survivability.	Main Stat Slot 4: Effect Resistance/Hit Slot 5: IRRELEVANT Substats: Effect Resistance, Effect Hit, ACC Notes: Max HP Damage does NOT Crit and is not affected by Resistances and DEF. Just build for utility.	Main Stat Slot 4: Effect Resistance/Hit Slot 5: IRRELEVANT Substats: EVA, Effect Resistance, Effect Hit, ACC Notes: Max HP Damage does NOT Crit and is not affected by Resistances and DEF. Just build for utility.
Stall Tank	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, Effect Resistance, Effect Hit, ACC, EVA Notes: a stall tank like Data Khun Mascheny would run Effect Resistance Slot 4 instead, but units like Zahard would follow this recommendation.	Main Stat Slot 4: Effect Resistance Slot 5: IRRELEVANT Substats: Effect Resistance, Effect Hit, ACC Notes: investing on stall tanks is often unnecessary, but if you really have to just aim for some utility stats like Effect Hit or Effect Resistance, depending on what their kit has to offer.	Main Stat Slot 4: Effect Resistance Slot 5: IRRELEVANT Substats: EVA, Effect Resistance, Effect Hit, ACC Notes: investing on stall tanks is often unnecessary, but if you really have to just aim for some utility stats like Effect Hit or Effect Resistance, depending on what their kit has to offer.
Utility Tank	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, Effect Resistance, DEF%, Effect Hit, ACC Notes: focus on getting 99% resistances, but better if you get 115% Resistances and some Effect Resistance. 115% Resistances is to account for the 16% Magic/Physical Pierce that Red Mask Hwaryun and Regular Lero Ro provide to their teams. Not necessary, but could be helpful.	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, DEF%, Effect Resistance, Effect Hit, ACC Notes: if your Tank has DMG Reduction or good DEF buffs, you should probably still run Resistances. If the tank you are building doesn't have that, then just run Effect Resistance/Hit in Slot 4 and call it a day.	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, EVA, Effect Resistance, Effect Hit, ACC Notes: if your Tank has DMG Reduction or good DEF buffs, you should probably still run Resistances. If the tank you are building doesn't have that, then just run Effect Resistance/Hit in Slot 4 and call it a day.
Support [Debuffer/Crowd Control]	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, Effect Hit, ACC, Effect Resistance Notes: focus on getting 99% resistances, but better if you get 115% Resistances and some Effect Hit. 115% Resistances is to account for the 16% Magic/Physical Pierce that Red Mask Hwaryun and Regular Lero Ro provide to their teams. Not necessary, but could be helpful.	Main Stat Slot 4: Effect Hit/Effect Resistance Slot 5: IRRELEVANT Substats: Effect Hit, ACC, Effect Resistance Notes: Effect Hit is important to apply Status Effects and Crowd Controls, in this scenario it is your priority.	Main Stat Slot 4: Effect Hit/Effect Resistance Slot 5: IRRELEVANT Substats: EVA, Effect Hit, ACC, Effect Resistance Notes: Effect Hit is important to apply Status Effects and Crowd Controls. EVA will be important as well for extra survivability.
Support [Buffer ONLY]	Main Stat Slot 4: Magic Resistance Slot 5: Physical Resistance Substats: Magic Resistance, Physical Resistance, Effect Resistance, ACC, Effect Hit Notes: focus on getting 99% resistances, but better if you get 115% Resistances and some Effect Resistance. 115% Resistances is to account for the 16% Magic/Physical Pierce that Red Mask Hwaryun and Regular Lero Ro provide to their teams. Not necessary, but could be helpful.	Main Stat Slot 4: Effect Resistance Slot 5: IRRELEVANT Substats: Effect Resistance, ACC, ATK%, Effect Hit Notes: As you don't apply Status Effects and Crowd Controls you don't have to build Effect Hit. You can just focus on Effect Resistance.	Main Stat Slot 4: Effect Resistance Slot 5: IRRELEVANT Substats: EVA, Effect Resistance, ACC, ATK%, Effect Hit Notes: EVA and Effect Resistance will be your main focus for extra survivability.

Now that we have a generic overview, let's go over why and when some stats are important to build.

Stat	Why is it good?	When should you build it?
Magic/Physical Resistance	It allows a unit to survive multiple hits without dying. Note: Resistances are effective up to 99%, but having more is still useful because it helps mitigate enemy Pierce and Resistance Decrease Debuffs. 99% is the minimum amount you should have for both resistances. Anything less than that will result in you taking massive damage even at lower deficits. e.g. The difference between 99% and 90% is a tenfold increase to the damage you take. 115% Resistances is a good value to aim at if you want to mitigate the 16% Pierce that units like Red Mask Hwaryun and Regular Lero Ro provide to their teams.	When you are playing below approx. 300 level deficit.
Magic/Physical Pierce	It allows a unit to ignore a % of the enemy Resistance. Note: it is subject to diminishing returns, so the more you have the lower the damage increase that you will get. It does NOT improve Max HP% Damage.	When the damage of your DPS unit scales with ATK%.
Critical Hit Rate	It allows a unit's attacks to crit for additional damage. Note: overcapping at times can still be good because enemies can have Critical Hit Resistance (This value would be subtracted to your Critical Hit Rate) It does NOT improve Max HP% Damage.	When the damage of your DPS unit scales with ATK% and they do NOT have Critical Hit Rate in their Revolution subnodes.
Critical DMG Increase	It increases the damage of a critical hit, it has a bade hidden 50% value that is not shown in the stat page of the unit. It does NOT improve Max HP% Damage.	When the damage of your DPS unit scales with ATK% and they aim for 100% Critical Hit Rate.
Effect Resistance	It allows a unit to resist Status Effect and Debuffs. This stat needs to be higher than the Enemy Effect Hit or it will not do anything. We get 80 Effect Resistance from Origin Orb, but this is often not enough and it is recommended that you level it up on units that have this stat as a Revolution subnode.	When a unit doesn't have built-in Status Effect Resistance or if their performance gets noticeably worse when affected by certain Debuffs.
Effect Hit	It allows a unit to successfully land Status Effect and Debuffs. This stat needs to be higher than the Enemy Effect Resistance or you will start to miss frequently. We get 80 Effect Hit from Origin Orb, but this is often not enough and it is recommended that you level it up on units that have this stat as a Revolution subnode.	When a unit has certain Debuffs or Status Effect they rely on to provide value to the team.
ACC	It determines whether a unit will land their attacks or not. Note: This stat needs to be higher than the Enemy EVA or you will start to miss frequently. If the attack does NOT land, neither will the attached Debuff or Status Effect, so it is important on Supports and Tanks too.	When hitting enemies with your attacks is crucial for the unit's kit to work. For example units that ONLY buff the team will NOT need this.
EVA	It allows a unit to dodge an enemy attack. Note: This stat needs to be higher than the Enemy ACC or it will not do anything. For EVA to be considered consistent enough, it should be at least 200 higher than the enemy ACC, if you cannot achieve this it is recommended that you do NOT go for this stat.	When you have a good Archive and you are running EVA on your Tri-Essence.

How does the Rerolling System works?

To use the reroll system you will need some specific items:

Soul Dice

Ignition Dice

Note: You can only use these items on a +20 Ignition Weapon piece.
I already made a video on this topic, feel free to check it out!

Soul Dice

The Soul Dice will change which stats received the upgrade during the leveling process and will also randomize the high/low rolls.
Refer to the image below for an example.
As you can see both the number of upgrades and the values changed.
For example the piece on the left went from no upgrades on Magic Resistance (2.5%) to 1 high roll upgrade (4.5%+4.5%).

Before the Soul Dice

After the Soul Dice

Ignition Dice

The Ignition Dice is a lot simpler, it will only randomize the values without changing the upgrade distribution.
For example, if you have a piece with 5 upgrades on Physical Resistance but the total value is only 10%, you could use the Ignition Dice to change High/Low rolls and get up to 27% Physical Resistance.

Before the Ignition Dice

After the Ignition Dice

Note: I would recommend to ONLY use the Ignition Dice on a piece that has at least 4 Upgrades on the stat you want, as they are 10 times more expensive than the Soul Dice.

Restoration Powder

If you had a decent roll before and the Dice you used messed it up, you can use the Restoration Powder to roll back to the previous values.

This item will only be needed when you are in the process of min-maxing your Ignition Weapons.

Weapon Fragments Exchange Store

How do you obtain the Dice?

1. Dismantling IW Pieces
You can obtain Weapon Fragments by breaking down unused Ignition Weapons:

C rank gives 1 Weapon Fragment

B rank gives 2 Weapon Fragments

A rank gives 3 Weapon Fragments

You can then get the Dice and the Restoration Powder from the Exchange Shop:

Soul Dice = 23 Weapon Fragments

Ignition Dice = 230 Weapon Fragments

Restoration Powder = 46 Weapon Fragments

On average, if you don't dismantle A rank pieces, you would get around 100 Weapon Fragments with 100 Master Keys.

2. Pioneer Shop
You can also get the Dice from the Pioneer Shop, but they feel a bit expensive:

Soul Dice = 2900 Pioneer Remnants [Exchange Limit 50]
Unlocked at Hard Mode 101-1

Soul Dice = 4100 Pioneer Remnants [Exchange Limit 30]
Unlocked at Hard Mode 151-1

Ignition Dice = 29000 Pioneer Remnants [Exchange Limit 10]
Unlocked at Hard Mode 151-1

3. Shop
You can buy 1 Soul Dice for 500 Suspendium in the Shop, daily limit of 5 exchanges.
I would NOT recommend it.

4. Event Exchange Shop
You can obtain the Dice also from the Story Campaign Event Exchange Shop:

Soul Dice = 1500 Event Currency [Exchange Limit 50]

Ignition Dice = 15000 Event Currency [Exchange Limit 20]
