Special Abilities
As a creature of living ice, a freezing flow is difficult to discern from its surroundings in icy and snowy land environments and when in icy water. A successful DC 15 Perception check is required to notice a freezing flow in these environments. Any creature that fails to notice a freezing flow and walks into it automatically takes damage as if struck by the ooze's slam attack. A freezing flow's slam attack is a slashing tendril of crystalline ice. It deals slashing damage instead of bludgeoning damage and has a critical range of 19-20. Each time a freezing flow deals cold damage with its slam attack or constrict ability, the target must succeed at a DC 17 Fortitude save or be staggered with numbing cold for 1 round. The save DC is Constitution-based.
