Sundance / Sela
A
Set Effect (2):
Increases ACC by 50 and Basic Attack Pierce by 12% until the end of the battle.
(Cannot be removed with buff removal skills.)
Set Effect (4):
With Sundance's protection, the wielder's basic attack DMG ignores 20% of the target's DEF and deals 200% of the wielder's ATK as additional DMG.
Additionally, the ability is enhanced every 5 sec once the battle begins, and the wielder's basic attacks deal 1% of the target's Max HP as additional DMG (100% of ATK if the target is a boss). (Max: 3 stacks)
Recommended on units that have AoE Basic Attacks or good amounts of ATK SPD increases in their kits.
The Max HP% Damage is decent enough that it could potentially be used on anyone if you need some extra damage.
This set lacks survivability, so your teams will have to keep the wearer of this set alive.
