Ultan of the Shell — guide

In short

Ultan Of The Shell is a Legendary Spirit Attack champion from the Dark Elves, with a 30% Ally ATK aura that works in every battle, a double-hitting A1 and an AoE Sleep. He is at his best in Faction Wars and Chimera, but a big part of his kit only switches on next to Oella. Build him for damage: ATK, crit and enough ACC to land his debuffs.

Strengths

• Aura: +30% Ally ATK in all battles — free value for any team, no booking needed.
• Clean Slate removes every debuff from himself, heals 20% of max HP per debuff removed, turns the leftover heal into a Shield, then hits one enemy ignoring Shields with +20% damage per debuff removed — a great way out of control.
• Ire hits twice, with a 30% chance to place 60% Decrease DEF for 2 turns; against a target under Increase DEF it strips the buff at 80% and cannot be resisted.
• Slumber Spores is an AoE Sleep on a 100% chance and refunds 15% turn meter each time that Sleep expires.
• Metabolism turns Regeneration healing into cooldown reduction on his own skills.

Weaknesses

• Without Oella he loses the 50% RES-ignore on A1/A3 and half the passive chance.
• Low base ATK (1,553) — the multipliers need real gear to hurt.
• Sleep is fragile control: any damage wakes the target, so it's a setup tool, not a lock.
• Base 101 SPD and 991 DEF — he can be killed before he takes a turn.
• Average legendary: outclassed by top damage dealers in most content.

Where to use

Best areas: Faction Wars (3.5) and Chimera (3.5). Then Clan Boss, Arena and Dungeons (3.0 each), where he works as a damage dealer with a useful A1 debuff. Weakest: Doom Tower (2.5), Hydra (2.5) and Hard mode (2.0) — Sleep does nothing to bosses and without Oella half his kit is trimmed.

Stats and gear

Priority: ATK% → C.RATE (aim for 100%) → C.DMG (200%+) → SPD (170–200 to move before the trash) → ACC (200–250 so Decrease DEF and Sleep actually land). HP and DEF only from leftovers; his 15,525 base HP is enough to survive behind the Shield. Sets: Savage as the main pick for penetration, Perception for speed plus accuracy, Fatal as the budget start. Relics: Malefic Talon, Irethi Coronet, The Cat's Gaze.

Masteries and blessings

Go down the PvE damage route for Dungeons, Clan Boss, Doom Tower and Faction Wars, and keep a separate Arena setup for PvP. Key picks: Pierce Defenses and Boss Slayer for thick targets and bosses. Blessing: Soul reap for extra damage on the target.

Tomes

Book A1 first: two levels push the Decrease DEF chance from 30% to 50%, and that is his main debuff. Then A3 (cooldown −1 at level 4) and A2 (cooldown −1 at level 5). If you don't have Oella, hold the books.

Verdict

Vault (fusion): only pull him out for an Oella pair, Faction Wars or the aura. As a standalone damage dealer he is solidly average.
