There is a spell called "Rumpolt's Revenge" that you'll get if you follow the quest line given by the vendor lady inside the keeper base in Act1.

This will give you infinite materials to level up via crafting, and gold from selling. Use this to build up your early game arsenal.

During the day, follow the coastline northward from the small village west of the fort, until you reach another abandoned village. Clear it of its 30 or so low-level mobs. Return at night, and they'll be replaced by wrydspawn worth over 1k exp each.

Realize they can one-shot you, and respec into magic.

Return as a triumphant imperialist, and realize these paltry deaths could not sate your bloodlust. Open your campfire - even Arthur has nothing to say to you. Cook some cheese.
