Which Class?

[-Catherin-]

Cleric. Get a friend with a dragon tooth to level up with, better to split exp with a friend than with your pet, and in a group pets wont take a share of it.

with two of them you can go for harder things and level up longer, i personally did Spirocs in TD.

Roll a cleric and have all of your buffs and heals already purchased so you can scribe them as you level up. this makes it even easier.
