The "Preacher" is not a standard character class in the base version of Torchlight 2
There are two dominant builds. Let’s break them down. Torchlight 2 Preacher Build
The Pagan’s Prayer (ring, mana on kill). The "Preacher" is not a standard character class
This build ignores guns entirely. You are a walking apocalypse. You stack Focus (for magic damage and mana) and convert all your damage to Fire/Holy. Torchlight 2 Preacher Build
Start as The Gospel of Fire until level 50. Respec to pistols only if you find legendary dual pistols with "Attack Speed +15%."
Focus on a single reliable AoE damage spell and mana regeneration.
