Up to about 24 or so stuff dies quick. You're prob better off meleeing and throwing in tainted breath. Topping off with inner fire and keeping sow up. Strength buffs are generally a good return on investment mana-wise. Canni dance with regen on.
At 29 things are hitting a bit harder. You get haste and should probably slow some stuff if its taking a while to kill it. Unless you have a solid weapon I'd prob pull with Tagar's insects and let her take over. Heal if needed but otherwise just canni-med (dance) to top off and keep buffs up. Until buffs last an hour it's a lot of upkeep so just manage your sanity and your hp/mana bars

Later on it's just a more extreme version but similar. Slow, is becoming a great friend. Heal, med/canni. Some Jaundiced Bone Bracer mixed in if you are a non-iksar.
