What does lucky do on aqw?

Answer 1

Luck is an attribute that is most helpful to mages and classes with a high critical strike chance, though any class can benefit from it.

Luck increases the chance to do a critical strike by a very small amount, at or around 1%, even when a high level.

Critical strike damage is greatly increased by Luck. When Luck is over 100, there is a more than 250% increase in crit damage.

To get the most out of the Luck attribute, develop the character's critical hit chance.
