Dorateen
Arcane
Pirates get backstab, which can inflict up to triple damage. That is three times warrior-type damage (with a weapon like Excalibur, for example) and persists throughout combat, once the pirate has successfully used stealth. I know not everyone likes the mechanic of hiding for one round, but it is fun to see the subsequent massive damage outputs. And there are end game enemies with high hit points who are otherwise difficult to hit.
