Avenger is a striker… but I don’t see the strike part… is getting to reroll your attack 1-3 times in a combat on one monster really that good? Or did I miss something else?
(I am sure this has been talked about already so fell free to point me to some other thread)
After you kill your first target, you can refocus on another target. Repeat until everyone is dead.
(In general it seems that avengers lack in raw DPS compared to TWF rangers, but with more hp and AC they should also be a lot more durable. They're like quasi-defenders.)
