The archer, playable-wise, just rules. Auto-heaing is a must, which means you don't need to constantly use healing or antidotes.
As for NPCs/Bosses, Mishaela was hilarious. "Come on, just try and hit me." She taunts you. Truthfully, this is the only match-up somewhat hard for the archer. If you don't find her right away, you're screwed.
