Dark Young, Adult

Adult Dark Young CR 11

This tree-like beast lurches forward on broad hooves. It has no face or eyes, but its oval body is ringed with gaping, whistling mouths. Long grasping tentacles wave madly from its dorsal side, slapping together like a dying fish flopping on a pile of carcasses.

Partly Hollow (Ex)

An adult dark young is treated as a creature one size category smaller than itself for determining the effects of high winds.


An adult dark young casts spells as a 10th-level sorcerer, and can choose spells from the druid list in addition to those from the sorcerer/wizard spell list. All of these spells are arcane spells (and do not require divine focus components) when cast.

Toxic Flesh (Ex)

A dark young’s flesh is toxic if eaten.

Adult Dark Young Flesh—ingested; save Fort DC 21; frequency 1/round for 6 rounds; effect 1d2 Constitution damage and 1 Wisdom drain; cure 2 consecutive saves.

A creature that eats dark young flesh is ten times as likely to fertilize a partner or become pregnant during intercourse for 24 hours after being affected by eating dark young flesh. All children born or sired from such couplings are Mythos satyrs, outer mutants, or other strange horrors. The save DC is Constitution-based.
