How to unlock the Specialist achievement in Death's Door - Definitive Guide
Easy as it sounds: choose the stat you're most interested in (probably best to do melee or magic damage) and ensure you prioritize leveling it up when you can. You can make this more difficult on yourself if you don't max one out before getting towards the end of the game as you may have to farm souls to get the required 1500 for the final upgrade, so knocking this out early will benefit you.
