So, here is the formula I figured out for RO mobile dmg calculation, the start formula I found on this post:, but wasn't very well explained or accurate, so based on tests, stats/gears/cards switches I could came to this formula: Have you ever wonder why your basic attack was 1k and went just to 1.5k after use a converter which supposedly does 200% dmg to a target? What about when your damage of 10k went up to just 11k after a 20% elemental card was equipped?
