Universal Tower Defense X Relics Tier List

Relic sets give your characters powerful bonuses in Universal Tower Defense, but some sets perform much better than others. Choosing the right relic set can make your characters significantly stronger and help you complete difficult stages more easily. However, with six different relic sets available, knowing which ones to farm and equip can be confusing.

This Universal Tower Defense Relics X tier list ranks every relic set from best to worst, explaining which sets you should prioritize and which ones work only in specific situations. Understanding relic set strength helps you make smart choices about where to spend your time farming.

Here's how every relic set ranks from S Tier (best) to C Tier (worst):

Tier	Relic Sets
S Tier	Laughing Captain, Ex-Captain Uraharo, Biju, Rebellious Shinobi
A Tier	Sun God, Berserk Shinigami, Reaper, Shadow Reaper, Great Mage, Reanimated Ninja
B Tier	Hokage, Bio-Android
C Tier	Junior Ninja, Super Roku

S Tier - Best Relic Sets in Universal Tower Defense X

These relic sets are the strongest in the game. They work well on most characters and provide powerful bonuses that help you win battles.

Relic Set	Bonuses	Why S Tier
Laughing Captain	Top + Bottom: +5% Damage, -5% Cooldown, +5% Range. Accessory: -5% Active Ability Cooldown	Works on almost any character without requiring specific conditions. The cooldown reductions help characters use abilities and attack more often, which is useful in every battle. The range bonus improves positioning and safety. This is the most flexible set that fits on any character in any situation.
Ex-Captain Uraharo	Top + Bottom: +10% Crit Rate, +25% Crit Damage. Accessory: Refund 5% Yen spent on upgrades	Gives huge bonuses for critical-focused characters. The +10% crit rate and +25% crit damage make critical hits happen more often and hit much harder. While the money refund is a small bonus on top, the critical bonuses alone make this set very strong for any character that benefits from critical hits.
Biju	Top + Bottom: +10% Damage, +20% Meter Gain. Accessory: When a meter bar is used, increase damage by 70% for 10 seconds	The 70% damage buff on meter use is one of the strongest short-term damage spikes in the game.
Rebellious Shinobi	Top + Bottom: When this unit applies any crowd control effect, gain 30% extra damage for 10 seconds. Accessory: When this unit swaps form or mode, permanently increase damage by 5% (stacks up to 6 times)	The permanent stacking damage from form swaps is incredibly strong on characters that change modes, letting you build up to +30% permanent damage over time. On top of that, the 30% damage burst from crowd control effects adds even more pressure. Units that apply CC and swap forms get enormous value from this set.

A Tier

Relic Set	Bonuses	Why A Tier
Sun God	Top + Bottom: +5% Damage, +10% Light Damage, +10% Water Damage, +10% Ice Damage. Accessory: Every 6 attacks, gain damage buff equal to unit's range for 7 seconds	Strong on high-range characters where the damage buff becomes very large. However, it requires building range to maximize the accessory bonus. Not as flexible as S Tier sets but very powerful when used correctly.
Berserk Shinigami	Top + Bottom: +10% Dark Damage, +10% Fire Damage, +10% Rose Damage, +10% Light Damage. Accessory: Every 5 hits, next attack deals 20% bonus True Damage ignoring all resistances	Excellent against armored enemies and bosses. The True Damage ignores all defense, and stacking four different elemental damage types gives it coverage across many unit types.
Reaper	Full Set: +2.5% Damage, +10% Range, +5% Crit Rate, +5% Crit Damage. Accessory: -7.5% Cooldown, +15% Range	A solid all-rounder that covers damage, range, crit, and cooldown all at once. The real value comes from the tag bonuses, which give massive extra stats to Peroxide, Reaper, Hollow, and Rage units. If your unit has one of those tags, this set competes with S Tier easily.
Shadow Reaper	Full Set: -7.5% Cooldown, +15% Range. Accessory: +2.5% Damage, +10% Range, +5% Crit Rate, +5% Crit Damage	Very similar to the Reaper set but with the cooldown reduction built into the main bonus instead of the accessory.
Great Mage	Top + Bottom: +10% Range, +20% Damage for 10 seconds on type advantage hit. Accessory: If this unit defeats a type advantage enemy, gain +40% Damage and -20% Cooldown for 10 seconds	When the type advantage condition is met, the damage and cooldown bonuses are among the strongest in the game.
Reanimated Ninja	Top + Bottom: +10% Damage, +30% DoT Damage. Accessory: Every 5th attack gains DoT Damage equal to its range for 10 seconds	The 30% DoT damage increase is really strong, and the accessory scales with range, meaning high-range units get a very large bonus every 5 attacks. If you are running a DoT-focused character, this is the set to use.

B Tier

Relic Set	Bonuses	Why B Tier
Hokage	Top + Bottom: +5% Damage, +10% Dark Damage, +10% Rose Damage, +10% Fire Damage. Accessory: Every 5 attacks, increases DoT Damage by 20% for 10 seconds	The elemental damage bonus covers the same Dark, Rose, and Fire types, making it another decent option for those unit types.
Bio-Android	Full Set: +10% Damage, +5% Range, -5% SPA, +5% Crit Rate, +15% Crit Damage. Accessory: +10% Damage to enemies under 50% HP	A decent all-rounder on paper with damage, range, attack speed, and crit all in one set. The problem is that the accessory bonus only works on enemies below 50% HP, which makes it more of an execute bonus than a reliable damage increase.

C Tier

Relic Set	Bonuses	Why C Tier
Junior Ninja	Top + Bottom: +5% Damage, +10% Wind Damage. Accessory: Increases buffs received by 1.1x	The set bonuses are the weakest in the game. Very limited use cases make this a last resort option.
Super Roku	Full Set: +10% Damage, +15% Crit Chance, +20% Damage if placed within range of a Saiyan unit. Accessory: 5% chance to stun enemies on attack	The +20% damage bonus for being near a Saiyan unit sounds great but is too restrictive in practice. You need to build your team around a specific unit type just to activate one bonus, and the 5% stun chance on the accessory is unreliable. The base stats are decent but not enough to carry this set on their own.
