Attack of the Swarm: Hive of Minds pg. 44
Through discipline or ill-advised testing, you’ve learned how to manifest mindscape effects in the real world. The resulting elements are temporary and sometimes insubstantial, fueled by your own reservoir of mental energy. Once per day, you can cast one of the following spells as a spell-like ability, pulling its effects from a mindscape and into the real world: creation (4th level) or holographic image (4th level). At 15th level, you can increase the spell level of these effects to 5th and you add holographic terrain to the list of available spells. At 17th level, you can use this ability twice per day, and at 18th level, you can use this ability three times per day. The saving throw DC of these spells is equal to 10 + the spell’s level + your key ability score modifier.
