Noxious Fumes

Requirements The belker is occupying the same space as a Medium or smaller creature

Effect The belker attempts to flow into the creature's lungs; the creature must attempt a DC 21 Fortitude save. On a failure, the creature partially inhales the belker and is Immobilized by the pain of the smoke rasping in its throat and lungs. The creature can attempt to exhale the belker by spending an action coughing and succeeding at a DC 21 Fortitude save.

Most of the belker remains outside the creature, so the belker can still act normally. If the belker moves out of the creature's space or uses again, the creature automatically exhales it.

Smoke Slash

Requirements The belker is partially inhaled by a creature

Effect The belker automatically deals its claw damage to the inhaling creature by forming a claw to slash and scrape the creature from within.
