Combat signature

Every third round she splits off a short-lived, low-HP mist duplicate of herself that also attacks - the first temporary combat decoy summon in this bestiary. On round six, a real epic Ruin.

D&D build

Monstrous levels (natural Hit Dice) + PRC Dragonheart Mage 11; 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.
