From Portals of Phereon Wiki

A skill that summons a Tentacle for the duration of the current battle. A Tentacle summoned during battle is a Token and will not be added to your party.

Creation's signature skill, only a few other characters have access to this, and most of them will only be available if you choose Creation as MC.

Creation also gets an Overworld ability with the same name, but it is NOT the same skill, and is exclusive to her. This version applies the same rules (summon strength is based on caster's size and Magic), but it additionally costs 10 stamina and adds the Tentacle to your party.
