Snake's Mane

HAZARD 7
Stealth +17 (trained) to discern the snake's mane from the surrounding vegetation
Description A tangle of feathery green vines appears innocuous but fires a spray of acidic barbs at anything that disturbs it.

Disable DC 27 Nature (expert) to strip the barbs from the vines, rendering them harmless, or DC 30 Stealth (trained) to move through the snake's mane without disturbing it

AC 22; Fort +12
HP 60 (BT 30); Immunities critical hits, precision; Weaknesses fire 10, slashing 10

Barb Spray

A creature enters an area containing snake's mane or the snake's mane takes damage


Effect The vine sprays a hail of acidic barbs in a 10-foot emanation. Any creature in the area takes 4d10+18 acid damage (DC 25 basic Reflex save). On a critical failure, the creature is also Blinded for 1 minute.

Note: A saving throw for this ability was not provided by Paizo. The DC presented here is a hard DC for the hazard's level based on the GM Core hazard building rules.

Reset 1 hour, as the vine grows a new set of barbs
