Universal Tower Defense X Raid Solo Guide

UPD 3.25 solo raid template for boss DPS, armor break, farm, support, relics, and safer clears.

Current Applicability

Last checked May 26, 2026

Use this as a boss template

Older Ragna-specific mechanics may rotate in and out, so this page now focuses on the solo raid structure that remains useful across boss events: damage window, armor break, economy, support, and relic setup.

Boss DPS: one unit must carry the damage check.
Break / debuff: bring any unit that increases damage taken, breaks armor, or controls the boss.
Farm: upgrade before the boss timer becomes impossible.
Relics: match carry relics to boss damage, not wave clear.

Verification note: current solo raid guidance is generalized from UTDX unit-role tier lists and the current relic/trait pages on UTDValues. Specific event boss names should be rechecked when a raid rotates.

Solo Raid Team Template

Core Slots

SSS

Boss Killer

Main DPS

Your strongest single-target or boss-pressure unit. This slot gets the best trait and relics.

Traits: Ruler, Duelist, Sacred

Break / Debuff

Damage amplifier

Use armor break, defense shred, stun, slow, or any boss-specific counter required by the raid.

Goal: make boss damage windows count

Farm

Upgrade tempo

Without economy, solo raids often fail because the carry reaches full power too late.

Trait: Fortunate

Support

Range / cooldown / control

Support keeps the boss in range longer and improves uptime during burst windows.

Use: boss turns, final phase

Raid Role Rankings

UPD 3.25

Tier	Role / Unit Type	Best Use	Raid Note
SSS	Premium boss DPS	Main carry	Dragon Warlord / Sharpshooter King style carries are safest when built well.
SS	Armor break / debuff	Damage window	Often more valuable than adding a second mediocre DPS.
SS	Farm unit	Upgrade tempo	Required for most solo attempts unless the raid is very short.
S	Control support	Stall / uptime	Buys more hits during dangerous boss movement.
A	Wave clear DPS	Add control	Useful only if the raid includes adds that threaten your base.

Solo Rotation

Simple Plan

Win the upgrade race

Opening: place cheap DPS and farm immediately.
Setup: max carry before investing heavily in side units.
Break window: time debuffs and burst together instead of using skills randomly.
Final phase: use control/support only when it extends carry uptime.

Frequently Asked Questions

Is this still only a Ragna guide?

No. It has been updated into a general solo raid template because event bosses rotate and old Ragna-specific details can become stale.

What should get my best relics?

Your boss killer. Raid clears usually fail on the boss damage check, not on normal wave clear.

Do I need armor break?

If the boss has mitigation, yes. A debuff slot can outperform another DPS if it makes your carry hit harder.
