Why Relic Comparison Matters in Universal Tower Defense X

If you've been grinding in Universal Tower Defense X, you already know that relics aren't just optional upgrades — they're the backbone of any end-game build. With so many sets, rarities, and stat combinations available, figuring out the universal tower defense x best relics to compare is the key to maximizing your unit's potential. Whether you're pushing through high-difficulty raids or optimizing your favorite DPS unit, choosing the wrong relic set can leave you falling short.

The relic system in UTD X is deep. You've got Top, Bottom, and Accessory slots, each offering different main stats and substats. On top of that, set bonuses and tag synergies can dramatically change how a unit performs. That's why knowing which relics to compare and prioritize is essential. This guide will walk you through the top relic sets, break down their bonuses, and help you decide which ones are worth your time and resources.

Understanding Relic Rarities and Stats

Before we dive into specific sets, let's cover the basics. Relics in Universal Tower Defense X come in five rarities: Rare, Epic, Legendary, Mythic, and Raid. Higher rarities unlock more substats and higher max levels, making them significantly more powerful.

Relic Rarity Comparison

Rarity	Max Substats	Max Level	Notes
Rare	1	6	Basic starter relics
Epic	3	9	Decent for early-mid game
Legendary	4	12	Strong mid-game option
Mythic	5	15	Top-tier standard rarity
Raid	5	15	Uses star system and tag bonuses

Raid relics are unique because they can roll with 1, 2, or 3 stars. A 3-star Raid relic offers +5% stats above a maxed Mythic relic, making them the ultimate chase items. They also feature tag bonuses that activate when equipped on a unit with a matching tag, adding another layer of strategy.

Main Stats at Max Level (Level 15)

Slot	Main Stat	Value
Top	Damage	+60%
Top	Crit Damage	+120%
Top	DoT Damage	+75%
Top	Hyper Armor Damage	+100%
Bottom	Range	+30%
Bottom	Cooldown	-22.5%
Bottom	Damage	+60%
Bottom	Crit Rate	+37.5%
Accessory	Elemental Damage	+30%
Accessory	Buff Potency	+45%

When comparing relics, always consider what main stat benefits your unit the most. A crit-based DPS will want Crit Damage on Top and Crit Rate on Bottom, while a support unit might prioritize Cooldown reduction and Buff Potency.

Top Relic Sets You Need to Compare

Now let's get to the heart of the matter: the universal tower defense x best relics to compare based on set bonuses and tag synergies. Each set offers unique benefits, and the right choice depends on your unit's role and team composition.

Sun God Set — Best for Range-Based Damage

The Sun God set is a standout for units that scale with range. Its Top + Bottom set bonus gives +5% Damage, +10% Light, Water, and Ice Damage. But the real star is the Accessory Set Bonus: every 6 attacks, the unit gains a damage buff equal to its range for 7 seconds. Since 1 Range equals 1% Damage, a unit with 100 Range gets a massive +100% Damage buff.

Bonus Type	Effect
Top + Bottom Set	+5% Damage, +10% Light/Water/Ice Damage
Accessory Set	Every 6 attacks: damage buff equal to range for 7 seconds

This set is ideal for long-range DPS units that can maintain consistent attack speed. The synergy between range and damage makes it one of the most powerful sets in the game.

Berserk Shinigami Set — True Damage Monster

If you're looking for raw power that ignores defenses, the Berserk Shinigami set is a top contender. Its Top + Bottom bonus provides +10% Dark, Fire, Rose, and Light Damage. The Accessory bonus is even better: every 5 hits, the next attack deals extra 20% True Damage and ignores all resistances.

Bonus Type	Effect
Top + Bottom Set	+10% Dark/Fire/Rose/Light Damage
Accessory Set	Every 5 hits: next attack deals +20% True Damage, ignores resistances

True Damage is incredibly valuable against high-defense enemies and bosses. This set is a must-compare for any unit that attacks frequently.

Ex Captain Set — Crit and Economy Hybrid

The Ex Captain set is perfect for crit-focused builds. Its Top + Bottom bonus gives +10% Crit Rate and +25% Crit Damage. The Accessory bonus refunds 5% of yen spent on upgrades, making it a great choice for long runs where you're constantly upgrading units.

Bonus Type	Effect
Top + Bottom Set	+10% Crit Rate, +25% Crit Damage
Accessory Set	Refunds 5% of yen spent on upgrades

While the economy bonus is nice, the crit stats are the main draw. Pair this set with units that have high base crit damage for devastating results.

Biju Set — Meter-Based Burst Damage

The Biju set is designed for units that rely on meter bars. Its Top + Bottom bonus gives +10% Damage and +20% Meter Gain. The Accessory bonus is where things get crazy: when a meter bar is used, increase damage by 70% for 10 seconds. This effect does not stack, but the burst potential is enormous.

Bonus Type	Effect
Top + Bottom Set	+10% Damage, +20% Meter Gain
Accessory Set	When meter bar is used: +70% Damage for 10 seconds (does not stack)

This set is ideal for units with powerful meter-based abilities. Timing your meter usage around the damage buff window is key to maximizing its potential.

Raid Relic Sets — The Endgame Chase

Raid relics are the pinnacle of the relic system. They offer the highest stat potential and unique tag bonuses that can completely transform a unit. When comparing Raid relics, you need to consider both the star rating and the tag synergy.

Reaper Relic Set

The Reaper set is a versatile option with solid all-around bonuses. Its Full Set Bonus provides +2.5% Damage, +10% Range, +5% Crit Rate, and +5% Crit Damage. The Accessory Set Bonus adds -7.5% Cooldown and +15% Range.

Tag	Bonus
Peroxide	+10% Damage, +5% Buff Potency, +8.5% Crit Damage
Reaper	+20% Hyper Armor Damage, +12.5% Armor Penetration, +15% Range
Rage	+25% Crit Damage, +10% Crit Rate, +10% Range
Hollow	+12.5% Damage, -7.5% Cooldown, +15% Range

The tag bonuses make this set incredibly flexible. Based on player experience, the Rage tag is particularly strong for crit-heavy units, while the Reaper tag excels against armored enemies.

Shadow Reaper Set

The Shadow Reaper set offers a different flavor, focusing on cooldown reduction and range. Its Full Set Bonus gives +7.5% Cooldown and +15% Range, while the Accessory bonus adds +2.5% Damage, +10% Range, +5% Crit Rate, and +5% Crit Damage.

Tag	Bonus
Peroxide	+10% Armor Penetration, +15% Hyper Armor Damage, -10% Cooldown
Reaper	+30% Elemental Damage, -12.5% Cooldown, -5% Damage
Rage	+15% Elemental Damage, -8.5% Cooldown, +10% Buff Potency
Hollow	+20% Crit Rate, +12.5% Crit Damage, +5% Hyper Armor Damage

Community reports suggest that the Reaper tag on this set is excellent for elemental damage dealers, while the Hollow tag is a hidden gem for crit builds.

How to Choose the Right Relic Set

With so many options, deciding which relics to compare and ultimately equip can be overwhelming. Here's a practical approach to narrowing down your choices:

Step 1: Identify Your Unit's Role

Primary DPS: Look for sets that boost Damage, Crit Rate, and Crit Damage. Ex Captain and Berserk Shinigami are strong contenders.
Meter-Based Burst: Biju set is your best bet for massive damage windows.
Support/Utility: Prioritize Cooldown reduction, Range, and Buff Potency. Laughing Captain or Junior Ninja sets work well.
Elemental Specialists: Sun God or sets with high elemental damage bonuses are ideal.

Step 2: Consider Tag Synergies

If you're using Raid relics, matching tags is crucial. A Peroxide-tagged relic on a Peroxide unit can unlock significant bonus stats. Always check your unit's tags before committing to a set.

Step 3: Evaluate Substats

Don't overlook substats. At max level, Mythic and Raid relics can have up to 5 substats. Look for complementary stats like Crit Damage on a crit-focused relic or Cooldown on a support relic.

Frequently Asked Questions

What are the universal tower defense x best relics to compare for new players?

For new players, focus on Epic and Legendary relics from the Sun God or Ex Captain sets. They offer straightforward bonuses that work well with most early-game units. As you progress, start farming for Mythic and Raid relics to replace them.

How do I get Raid relics in Universal Tower Defense X?

Raid relics are obtained from raid content. Based on community reports, they have a low drop rate and can roll with 1, 2, or 3 stars. 3-star Raid relics are extremely rare but offer the highest stat potential in the game.

Can I mix and match relic sets?

Yes, you can mix Top and Bottom relics from different sets, but you'll lose the set bonus. For maximum power, always equip a Top and Bottom relic from the same family to activate the set bonus. Accessories can be mixed, but many sets also offer an Accessory Set Bonus worth pursuing.

Are substats more important than set bonuses?

It depends on your build. A perfect set of substats can sometimes outperform a mediocre set with a strong bonus. However, for most players, focusing on set bonuses first and then optimizing substats is the most efficient path. Always compare both when deciding which relics to keep.
