What Siren of the Void Does

Siren of the Void is a dual elemental boost: Dark skill damage +30% and Ice skill damage +30%. That's two emperor-tier boosts ( Lord of the Underworld + Ice Emperor ) in a single slot — on a Pal that attacks with Dark or Ice it's among the most efficient damage passives in the game, and Dark/Ice hybrids get full value from both halves. It stacks with the single-element boosts for truly dedicated builds.

What Siren of the Void Does Not Do

Nothing for other elements — on a Fire or Neutral attacker the slot is dead weight.

How to Get It

Siren of the Void never rolls on wild Pals and isn't on the surgery menu — it's the signature of Bellanoir Libero , the summoned raid boss (the base Bellanoir doesn't carry it). Earn your own from the raid, then breed the passive onward — it inherits like any other, so one Bellanoir Libero can seed your whole Dark/Ice line via the Breeding Calculator.
