Plant When it isn't in danger, the corpseroot spends 1 minute rooting to the earth, becoming planted in place. While the corpseroot is planted and immobile, creatures must actively Seek and succeed at a DC 36 Perception check (DC 40 in forests) to detect the corpseroot's true nature.

Axe Vulnerability The corpseroot takes 10 additional damage from axes.

Blight (aura, necromancy, poison, primal) 30 feet. A plant entering or starting its turn in the corpseroot's aura begins to wither and must succeed at a DC 27 Fortitude save or become sickened 2 (sickened 4 on a critical failure). A plant that succeeds is temporarily immune for 1 minute. A plant that stays in the aura for 7 consecutive days must succeed at a DC 27 Fortitude save or die. If the plant was a creature or tree, it rises as a corpseroot. The newly risen corpseroot can't create more corpseroots but has all other corpseroot abilities. Plants that are neither magical nor creatures automatically fail saves against blight.

Grab (page 212)

Take Root [>] (necromancy, primal) Frequency once per round; Requirements The corpseroot has a creature grabbed or restrained; Effect The corpseroot buries its roots into the creature, dealing 1d6+11 piercing damage and draining the target's life force (DC 30 basic Fortitude save). On a failure, the creature is drained 1 (or increases the value by 1 if already drained), and the corpseroot regains 10 HP. If this would make a creature drained 5, the creature dies.
