Attack782 Guide: Urost The Soulcage
In short
Urost The Soulcage is a Legendary Void HP champion from the Undead Hordes — a poison-driven tank/support whose damage and shields both scale off HP. He shines in Clan Boss, Doom Tower and Faction Wars where poisons on enemies switch on his control. Build priority: HP and Speed first, then Accuracy.
Strengths
- HP scaling on damage, shields and survivability — one stat does everything.
- Eruption of Sulphur is mass control: reduces turn meters of poisoned enemies, applies a 30% SPD down on targets with 2+ poisons and a 1-turn Stun on targets with 3+ poisons.
- Villainy gives the whole team Increase ATK 25% plus a 2-turn ally Shield, and that same buff feeds his passive.
- Passive: 5% Poison on attackers, Provoke on attackers when an ally with Increase ATK is hit, grows his own MAX HP and cuts enemies' MAX HP through his poisons.
- Aura: +80 RES in all battles — useful everywhere.
Weaknesses
- 95 base Speed — without Speed gear he barely moves.
- His control is conditional: no poisons on the target means no turn meter cut, no SPD down, no Stun.
- Arena 2.5/5: no cleanse, no immunity, no burst damage.
- Passive MAX HP reduction does not work on bosses and his own HP gain caps at +50%.
Where to use
Clan Boss first (4/5) — poisons, HP scaling and self-shields make him a sturdy damage dealer there. Then Doom Tower (4/5) and Faction Wars (4/5), where his control and aura patch up a thin roster. Hydra (3.5/5) works well against targets already carrying poisons. Chimera, regular dungeons and Hard mode sit at 3/5 — he is just a solid support. Arena (2.5/5) is his weakest spot: against fast PvP teams he has nothing to answer with.
Stats and gear
HP% first — aim for 80–100k HP, more for Clan Boss. Speed 200+ (220+ in CB) so Villainy and Eruption of Sulphur keep cycling. Accuracy 200–250 so his poisons actually land and unlock the control. Resistance comes from the aura; crit stats are irrelevant. Sets: Speed, Accuracy, Immortal or Life — don't sacrifice Speed and Accuracy for raw HP.
Masteries and blessings
Offense plus Defense trees. Key picks from the list: In For The Kill, Survival Speed, Pouncing Strike, Unflinching. Relics: Molten Deathbell, Golden Elixir, Arachnelixir.
Tomes
Book Villainy first: only 2 books give -2 cooldown (5 → 3), so the team Increase ATK and shield stay up nearly all the time. Then Eruption of Sulphur — extra debuff chance and -1 cooldown at level 7. Leave the A1 books for last; they only add damage and shield size.
Verdict
A durable Void tank with HP-based damage and poison control — he delivers in Clan Boss, Doom Tower and Faction Wars. Site verdict: build him.
