in Tales of Maj Eyal (a roguelike) there's a Gunslinger talent that lets you evade like 40% of hits
and another talent that lets you retaliate with a gunshot every time you evade an attack
I encounter a boss, who's a Time Warden. Time Wardens are a class that gets lots of extra turns from their buffs.
Charged me with 9 free turns worth of buffs. 15 levels higher than me.
Whiffed 10 turns of attacks (incl. charge) with dual wield, instantly evaporated to the retaliation shots before I could consciously do anything to them.
