Universal Tower Defense Traits System

Traits are one of the most critical mechanics in Universal Tower Defense. They are passive buffs that can multiply a unit's damage, range, or attack speed, turning a standard unit into a god-tier carry. This page covers every available trait, their drop rates, and which units they suit best.

As of Update 1.0.6, there is a hidden 'Mythic Pity' at 1,000 Rerolls which guarantees a Mythic trait or higher. There is no official 'Secret Pity' confirmed by developers yet.

What is the best Trait combo for Jinoo (Monarch)?Meta: Ruler + Godly
