Artifact — Ossuraxis's Prism Shard
Recovered from Ossuraxis. Resref shl4_oss_art.

Combat signature

Every third round he fires a randomized prism ray - one of three effects - at a RANDOM nearby foe rather than the nearest one, the first randomized-effect, randomized-target mechanic here. On round six, a real epic Dragon Knight.

D&D build

Monstrous levels (natural Hit Dice) + PRC Diamond Dragon 11; boss flags BOSS, CLEAR, LOOPS, TYPE 26, USED 0, and R13_UNIQUE. The Epic Dragon Knight 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.
