Artifact — Mossback's Verdant Heartwood
Recovered from Old Mossback. Resref scv9_mos_art.

Combat signature

Every third round his Verdant Ward heals him a flat percentage of his own max HP - no prior boss here out-heals itself on a timer. On round six, a real epic Ruin.

D&D build

Monstrous levels (natural Hit Dice) + PRC DragonShaman 9; boss flags BOSS, CLEAR, LOOPS, TYPE 26, USED 0, and R13_UNIQUE. The Epic Ruin capstone is delivered by the dedicated round hook after the visual telegraph, exactly like every real Epic Spell in this bestiary since round 1.

Caller and encounter

One blueprint only. The Bestiary Caller uses the normal BC_Spawn contract, while the reserved Sparky case maintains a 12% always-on, count-one encounter definition, capped at one live spawn per area.
