Solasta: Crown of the Magister

From the main menu, click 'Characters', then 'New character'. Choose Rogue for the class, and continue through the process.
Once you finalize the identity, the achievement will pop shortly after.

For this achievement, you need to make a rogue. Rogues are kinda useless in Solasta due to the lowlife background, knock spell, low damage of traps, and save-scumming. They also do lower damage than a paladin or ranger, usually. If you do play one, here’s a build:
