Demon

I think the Demon class is the strongest The Forge race overall because it's so damage-focused. Demonic Powers boosts Movement Speed, Physical Damage, Fire Damage, and Attack Speed – all by 20%.

Cursed Aura activates in combat, creating an area around you that deals damage equal to 10% of your weapon each second. Devil's Finger gives a 20% chance to create a hellfire circle around you when you dash, dealing 45% of your weapon damage for a few seconds. Backfire gives you a 25% chance to burn enemies when you take damage.
