Astral constructs you create with this form take on a distinctive apelike appearance, with the exception of a third armlike limb that grows our 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 (EPH 186).
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.
