## Ectopic Form, Emerald Gyre Astral constructs you create with this form take on a distinctive apelike appearance, with the exception of a third arm like limb that grows out of the middle of the back. **Benefit:** When you create an astral construct using this form, you shape a third arm in the middle of the creature's back that is used to assist in grabbing opponents, granting the construct the improved grab menu B ability. An emerald gyre construct is the same base size as an unmodified astral construct fashioned with the _astral construct_ power. An emerald gyre appears as a green humanoid (size depends on the level of construct) that possesses a third arm growing from the middle of its back.
