Current formula for Enhance attribute for Wugu poison is something like this.
[Your ATK + (Skill ATK * Enhance Attri) + gem ] = Total skill damage per hit
Which mean now enhance attri only effect the skill’s ATK.
While ktos current patch they use formula like this.
(Your ATK + Skill ATK + Gem or another sourch of ATK) * Enhance Attri = Total damage per hit
Which is alot better
For example, Wugon Gu have the 200 skill atk and you have base 800 ATK = total 1000 skill damage per hit.
if you dump your money to get 50% Enhance attribute, the current formula will boost your damage to 1100 damage per hit (Which is wast of money seriously). while new formula give you 1500 damage per hit
ps. I’m forgot to mention that it’s the poison formula
