ATK stats
 

Hey, What is the ATK stat for ? More ATK = more chances to hit mobs ?
Thanks for help !

It increases your odds of landing a higher hit on the mob. If your weapon hits for between 5-100 and you are able to increase your attack, the chances of it hitting a number higher on that interval increases. A low attack will hit lower on average.

I don't think that's entirely true. Displayed ATK is a combination of your chance to hit (weapon skill) and power (STR, etc). Weapon skill has nothing to do with how hard you hit, only how often you hit versus how often you miss.
