There Are No Classes in Undecember — Only Power

In Undecember, you don’t choose a class—you build your own path. Every weapon, every rune, and every stat is part of a system that gives you total freedom to define your style of destruction.

Want to hurl fireballs with a two-handed axe? Launch poison traps while wearing heavy armor? You can. Customize builds around core mechanics, amplify them with support runes, and evolve through loot-driven progression.

Strength comes from how you combine gear, stats, and skills. There are no templates—only tools. Link damage modifiers, defense breakers, or crowd control into devastating combos, and reshape your character on the fly.

Each build tells a story of trial and experimentation. Fine-tune over time, shift focus between seasons, and create something completely your own. No restrictions. No limits.

Whether you’re chasing top-tier clears or just experimenting with wild rune chains, Undecember gives you the sandbox to master your vision. The grind is yours to shape.

The chaos is calling. Will your build rise to the top—or be lost to the dust?
