Palworld: How to Beat Xenolord (Ultra) With a Univolt Cryst Raid Army

Xenolord (Ultra) is a Dark and Dragon raid boss that lands at Level 80 with roughly two million HP and a 10-minute clock, which makes it a pure damage race. Its typing leaves it doubly exposed to Ice, and a full base slot of Level 80 Univolt Cryst turns that weakness into a freeze lock the boss rarely escapes.

Quick answer: Deploy a Level 80 Univolt Cryst army at the Summoning Altar, bait Beam Slash from the ground, freeze the boss before it can cast Omega Laser, then mount Frostallion and fly a high counter-clockwise circle while emptying the Legendary Plasma Rifle into Xenolord’s head.

Xenolord (Ultra) raid rules and weakness

The Ultra version is summoned by placing the Xenolord (Ultra) Slab in a Summoning Altar, and the fight is labelled Invader from Space (Ultra) in the arena. Dying does not end the raid. You only lose if the timer expires or the Pal Box is destroyed, so the real enemy is the clock.

Property	Detail
Element	Dark / Dragon
Weak to	Ice and Dragon
Level	80
HP	Around 2 million
Timer	10 minutes
Loss conditions	Timer expires or Pal Box destroyed

Raid boss aggro now follows whoever deals the most damage. Because a player build stacked with damage buffs out-damages the base Pals, Xenolord tends to chase you rather than the army, which is exactly what you want. Keep your distance from the raid Pals and they take almost nothing.

Univolt Cryst army build: active and passive skills

Univolt Cryst is an Ice-element Pal that sits at #130 in total stats, so it is not carried by raw numbers. What makes it work is the attack set. Its ice moves land constantly, and repeated hits keep the freeze status refreshing on the boss.

Slot	What to run
Active skills	Ice Gate Strike, Double Blizzard Spike, Diamond Rain
Passive skills	Lunker, Siren of the Void, Imperious, Serenity
Level	80

Fill the base slots with this same build rather than mixing in filler Pals. Overlapping ice attacks from a full army are what pin Xenolord in place, and a half-built roster leaves gaps where the boss recovers and starts casting.

Party Pals for ice and weak point damage

The five party slots exist to multiply your own gun damage, not to add another attacker. Frostallion doubles as your mount and converts your shots to Ice, while the rest stack ice and weak point bonuses on top.

Pal	Role in the party
Frostallion	Flying mount, resists Dragon attacks, converts player damage to Ice
Selyne	Player attack boost
Moldron Cryst B	Ice damage boost
Vanwyrm Cryst	Weak point damage boost
Cryolinx Terra	Weak point damage boost

Note: setting Frostallion to a defensive stance keeps it from charging into the boss and eating attacks, which matters when you need it alive as a mount during the add waves.

Player gear and weapons for the Ultra raid

Three weapons cover the whole fight. The Legendary Drone Launcher provides passive damage while you reposition, the Legendary Plasma Rifle handles precise head damage, and the Tactical Grenade Launcher is the burst option that shortens the clear.

Item	Why it is equipped
Legendary Drone Launcher	Deploys drones that keep chipping the boss
Legendary Plasma Rifle	Sustained head damage on the weak point
Tactical Grenade Launcher	High burst damage for a fast clear
Phantom Ring	Extends dodge invisibility, making Cosmic Meteor far easier to avoid
Warsect Terra’s Belt, Silveg’s Emblem, Dogen Emblem	Accessory damage and survivability

How to run the Xenolord (Ultra) fight

Deploy the full Univolt Cryst army into the arena, then activate the Summoning Altar with the Xenolord (Ultra) Slab. Let the army spread out before the boss lands so the first volley of ice attacks connects immediately.

Start the fight on foot rather than in the air. Standing on the ground baits Beam Slash as Xenolord’s opening move, which is far easier to read than the ranged casts it uses against an airborne target.

Get the freeze on before Omega Laser goes off. With the army already attacking, your own ice-converted shots push the boss into frozen status quickly, and a frozen Xenolord cannot start the cast.

Deploy the drones, then aim for the head with the Legendary Plasma Rifle. The head is the weak point, and it is where the Vanwyrm Cryst and Cryolinx Terra bonuses actually pay off.

When Xenolord rises and spawns Xenovaders and Xenogards, mount Frostallion and fly a wide counter-clockwise circle high above the boss. The constant turn keeps the adds’ projectiles behind you and pulls their attacks away from the raid army.

Clean up the remaining adds, then return to the boss and keep firing into the head until the bar empties. The Tactical Grenade Launcher is worth saving for this stretch if the timer is getting tight.

Tip: your position dictates what the boss throws out. Staying grounded pulls melee-range attacks like Beam Slash, while hovering above invites Omega Laser, Dark Wisp, and Cosmic Meteor. Switching between the two on purpose is how you steer the attack pattern.

How to confirm the clear and what drops

A successful run ends with the BOSS ELIMINATED banner on screen, followed by the reward window. Clearing the Ultra fight hands back another Xenolord (Ultra) Slab, so you can immediately queue the next attempt as long as you have a fresh Summoning Altar, along with Ancient Civilization Core, a Training Crystal, and a Xenolord Shard.

The Summoning Altar is consumed every time you summon, so keep Stone and Paldium Fragment stored beside it if you plan to farm the raid back to back.

Why the run fails

The army is below Level 80, so freeze uptime drops and Xenolord gets full casts off.
You open the fight airborne, which skips the Beam Slash bait and starts the boss on its ranged pattern.
You hover low or close to the base Pals, pulling add fire onto the army instead of away from it.
You body-shot the boss instead of hitting the head, wasting the weak point damage bonuses.
The 10-minute timer expires or the Pal Box is destroyed.

Once the army, party, and gear are locked in, the fight settles into a repeatable rhythm. Bait on the ground, freeze early, head damage when the boss is pinned, and circle high whenever the adds show up. From there the Ultra raid becomes a farm rather than a wall.
