There isn't much direct heal, but plenty of support style builds. Also plenty of caster DPS builds and hybrid versions of caster and support. Many options, let's narrow it down.
How to deliver damage? Self cast, spell totem(s), traps (that you throw), or proc spells a on critical strike with an attack?
Preferred spell style? Either projectiles released from you, totems, or traps, or area of effect skill targeting/channeling.
Any preferred damage type? Fire burns, cold chills and freezes, lightning shocks (enemies take increased dmg when shocked), chaos is immune to reflect, or physical damage, which stuns?
Hardcore or softcore? I play HC almost exclusively but would suggest that you play a SC temporary league to learn the game. I will guide you to a more HC style of build if you want.
