I'm trying to see how far I can get in the SMC. Fast healing is an obvious advantage, so a Candle-born healer is one thing I'm trying out. But which race? Trolls add another healing bonus (though I'm told it's not substantial), but their most significant attribute is the slow leveling. Not sure how that affects the difficulty. Does it make the game easier (because the monsters level up slower too, giving more time for items and weapon marks) or harder (because it takes longer, with more opportunities for the RNG to kill you)?
(Or is there something obvious I'm missing that makes the Healer class a bad strategy entirely?)
