Flowing Engulf

Your eidolon Strides up to double their Speed and can move through the spaces of any creatures in their path. Any creature of the eidolon's size or smaller whose space your eidolon moves through is engulfed unless it succeeds at a Reflex save against your spell DC. Your eidolon can attempt to engulf the same creature only once in a single use of Flowing Engulf, and they can contain as many creatures as can fit in their space.

An engulfed creature is pulled into your eidolon's body. It is Grabbed, Slowed 1, and moves along with your eidolon as long as it is engulfed. It can get free by Escaping against your spell DC, moving to a space of its choice adjacent to your eidolon.
