Universal Tower Defense Traits

Trait system, S-tier traits, and rerolling strategy

Trait System Overview
Passive buffs that significantly enhance unit performance

Traits are passive buffs of various rarities that can be rerolled using trait reroll items. The right trait can transform a good unit into a meta-defining powerhouse. Each unit can have one trait, and finding the optimal trait is crucial for endgame content.

S-Tier TraitsGame-changing passive buffs
Meta-Defining Traits

Ruler

+200% Damage

The most powerful damage trait. Especially strong on Berserker (Enraged), Sung Jinwoo, and Rule (ROOM). Priority reroll for Challenge mode units.

Eternal

Infinite Scaling

Essential for Infinite mode. Units gain permanent buffs over time. Best on Jinoo (Monarch), Dragon Silver, and Scarlet (World).

Sacred

Massive Power Buff

Extremely powerful for both Infinite and Virtual Realm. Alternative to Eternal for scaling content. Works on most top-tier units.

Duelist

Critical Strike Scaling

Absolutely essential for Kriatu (Cheater). Enables his crit-based damage ramping. Also strong on other crit-focused units.

A-Tier TraitsStrong situational buffs
Specialized Traits

Fission

Best for DOT-focused units like Admiral (Magma). Amplifies damage over time effects.

Wizard

Good for ability-based units. Increases skill damage and reduces cooldowns.

Brawler

Solid damage increase for physical attackers. Good budget option if you cant get Ruler.

Demolisher

Strong against high-HP enemies. Best for boss-focused content and story mode.

Assassin

Increases first-strike damage. Useful for units with high initial burst potential.

Berserker

Damage increases as HP depletes. Risky but rewarding in certain scenarios.

Trait Rerolling Strategy
Maximize your resources and prioritize correctly

Priority Order for Rerolling

1

Sung Jinwoo - Get Ruler trait for meta-defining Infinite mode performance

2

Kriatu (Cheater) - Duelist is absolutely mandatory for his kit

3

Berserker (Enraged) - Ruler trait makes him top 3 DPS in game

4

Your main carry units - Focus on units you use most frequently

Tips for Efficient Rerolling

  • Save trait reroll items for S-tier and Mythic units
  • Don't waste rerolls on units you won't use long-term
  • Match traits to game modes - Ruler for Challenges, Eternal for Infinite
  • Some units have trait synergies with their abilities - research before rerolling
  • B-tier traits are acceptable on secondary units to save resources
