Memory of Osoyo

COMPLEX HAZARD 5
Stealth +12 (expert)
Description The party's memories of Osoyo coalesce into a titanic mirage in the storm clouds above.

Disable DC 22 Occultism (trained) or DC 24 Arcana (trained) to divert the memory's rage; three total successful checks are required to disable the hazard


Glacial Gust
Trigger The characters' shared vision during Event 15 subsides

Effect The memory of Osoyo unleashes a tremendous sigh of freezing wind, coating the deck of the Mermaid's Tears in ice in a 60-foot cone. (The hazard can choose any point for the cone to originate.) The area becomes difficult terrain. Creatures in the area must succeed at a DC 26 Fortitude save or take 1d6 persistent cold as the freezing wind cuts to the bone. The hazard then rolls initiative.
Routine (1 action) The memory of Osoyo gives a keening scream that shatters the layer of ice coating the deck of the Mermaid's Tears. Any creature on difficult terrain created by the memory's Glacial Gust takes 2d8+7 cold (DC 26 basic Reflex) from the icy shrapnel.
