Trigger Ezio summons the swarms

Effect The swarms coalesce in nauseating fashion. Each creature in the room must succeed at a DC 24 Fortitude save or become Sickened 1 (Sickened 2 on a critical failure). The hazard then rolls initiative.

Routine (1 action) The bats and rats bite all creatures in the room, doing 2d8+3 piercing damage (DC 24 basic Reflex save). On a failure, the creature also takes 3 persistent bleed damage.
