Devouring Dark Form
Your apparition's dark power blends with your physical body, allowing you to take on terrifying characteristics of creatures that lurk in dark places. Your arms and legs transform into twisting tentacles. You gain a tentacle unarmed attack with 10-foot reach that deals 1d8 bludgeoning damage and has the grapple trait. The first time you Sustain this spell each round, you can attempt a single Grapple check with your tentacle against a creature within its reach.

Traits
This indicates abilities from the animist class.
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
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.
