Snake Fangs
Your jaw unhinges as your teeth extend into wicked fangs. For the spell's duration, you gain a fangs unarmed attack. They're a finesse, grapple, unarmed attack that deals 1d8 piercing damage and an extra 2d10 poison damage. If you have a creature at least one size smaller than you Grabbed with your fangs, you can use the Swallow Whole ability that deals 4d6 bludgeoning damage and has a Rupture value of 17. A swallowed creature is transported to an extraplanar space that resembles the inside of a snake's stomach, so when it gets free, it appears in a space adjacent to you. If you're killed or the spell ends, the swallowed creature is immediately freed.

Traits
An action with this trait requires a degree of mental concentration and discipline.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
Effects that slightly alter a creature's form have the morph trait. Any Strikes specifically granted by a morph effect are magical. You can be affected by multiple morph spells at once, but if you morph the same body part more than once, the second morph effect attempts to counteract the first (in the same manner as two polymorph effects, described in that trait). Your morph effects might also end if you are polymorphed and the polymorph effect invalidates or overrides your morph effect. The GM determines which morph effects can be used together and which can't.
