An eidolon learns to cast a powerful spell as a spell-like ability. Select one spell from the following list: arcane sight, create food and water, cure serious wounds, daylight, fireball, fly, gaseous form, lightning bolt, major image, stinking cloud, tongues, or water breathing. This spell can be cast once per day as a spell-like ability. The caster level for this evolution is equal to the eidolon's Hit Dice – 2. The save DC for this spell is 10 + 1/2 the eidolon's HD + the eidolon's Charisma modifier. The eidolon must have a Charisma score of at least 13 and must possess the major magic evolution to take this evolution.
The summoner must be at least 11th level before selecting this evolution. This evolution can be selected more than once. Each time an eidolon selects this evolution, it applies to a new spell from the above list.
