About Undecember
Undecember is a hack-and-slash game set in Traum, a world created by 12 divine beings who shared their powers and lived peacefully with their descendants. That peace ends when the unexpected 13th being, the Evil God Serpens, comes into existence. You defeat enemies to gain strength and obtain new items, then shape your character around your preferred combat style.
Build your character
Undecember has no defined classes. After customizing a character, you can freely change its gear and skills to suit your playstyle. Builds fall into Strength, Dexterity and Intelligence types, but gear and skill combinations are not restricted: you can cast magic with a sword, summon minions with a bow or create other builds.
Combine runes
Skill Runes provide skills, while Link Runes modify their effects. You equip them in the Rune Cast, and obtain them by farming or completing quests. Runes have levels and grades that you can upgrade using materials found through farming.
