How to Get Xenolord: Slab Locations and Raid Fight
Updated 2026-07-23
Xenolord is the mechanical dragon from beyond — a raid boss that fights like a warship, cycling lasers, satellites and orbital strikes. It's the last of the four summonable raids, and like its siblings the fight starts with a Slab built from fragments. Every source with real odds, the full weapons manifest, and the Ultra version that shrugs off nearly everything you throw at it.
How to Get the Xenolord Slab
Craft the 
Xenolord Slab from 4× 
Xenolord Slab Fragment and take it to a Summoning Altar:
| Source | Chance |
|---|---|
| Hard Volcano & hard Snow Pal Expeditions | Guaranteed |
| Sakurajima / Dark Island / Sky Island / World Tree expeditions | ~33% |
| Tier-2 cavern chests & late-game faction camp chests | ~33% |
The Fight — Abilities Explained
The summoned Xenolord arrives at Level 65 with warship scaling: roughly 280× normal HP, 5× damage, and it absorbs about two-thirds of incoming hits. The arsenal reads like a mech catalogue — Cosmic Meteor warps meteors onto your head, Satellite Bit deploys autonomous laser drones, Astral Ray and Omega Laser sweep the arena with converging beams, and Beam Slash punishes anything in melee range.
As a Dark/Dragon type it takes real extra damage from Ice and Dragon attackers — one of the few raids where the type chart genuinely helps. Keep the squad spread against the meteor drops, and check Xenolord's full page for stats and breeding.
The Ultra Version
The 
Xenolord (Ultra) Slab — 4× 
Ultra Slab Fragments — summons a Level 80 monster with around 420× HP, 13× damage, and armor that lets through only about 9% of your damage. Alongside Ultra Hartalis it sits at the very top of the difficulty curve; compare them all on the raid boss overview.
