Perilous Flash Flood

Stealth +22 (expert)

Disable three DC 35 Athletics, Crafting, or Survival checks to move or construct barricades strong enough to create a shelter from the flood. While this creates a safe place to stand, creatures outside of the barricaded area may still be in danger depending on the nature and the source of the flood.

Burst Free [Reaction]

Routine (1 action) The flood advances forward 60 feet, crashing into all creatures within its area. Each creature must attempt a DC 30 Fortitude save as the floodwaters pummel them and pull them downstream. The amount and type of damage dealt are based on the nature of the flood, and certain types of floods impose additional effects.

Inside the flood, moving at all takes a DC 20 Athletics check to Swim. A creature that fails to Swim in a given round risks drowning.

• Critical Success No damage.
• Success Half damage.
• Failure Full damage, and the current drags the creature 10 feet.
• Critical Failure Double damage, and the current drags the creature 20 feet.

Flood Types

• Acidic Runoff 1d12 bludgeoning plus 1d12+8 acid. A creature that critically fails its save also takes 2d6 persistent acid damage.
• Battering Waves 2d12+10 bludgeoning.
• Repulsive Refuse 2d12+8 bludgeoning. Anyone caught in it attempts a DC 29 Fortitude save: sickened 1 on a failure, sickened 2 on a critical failure. Touching the water also exposes a creature to filth fever (DC 20 Fortitude).
• Sharp Debris 1d12 bludgeoning plus 1d12+12 piercing.
• Sticky Goo 2d12+6 bludgeoning. Each creature in the flood attempts a DC 29 Reflex save at the start of its turn: on a failure, a -10-foot circumstance penalty to all its Speeds for 1 round; on a critical failure, immobilized for 1 round instead.
