Invoke the Lord of the Five Leaves

Minimum Spell Level: 7th.

Your type changes to outsider with the devil, evil, lawful, and native subtypes. You can, as a full-round action, cast a form of the dragon spell with a spell level one less than the spell slot you dedicate to this invocation (including alternatives to that spell, such as form of the alien dragon). Your type remains outsider with the evil, devil, lawful, and native subtypes while that spell is in effect.
