Description: You have learned a few of the words that were spoken to create the world.
Prerequisites: INT 15, CHA 15, Base Will Save Bonus +5
You can use the Words of Creation to enhance bardic music, to help cast good spells and create good magic items, and to enhance the process of creation (See Words of Creation). Talk to the DM before you take this feat.
Special
This is an Exalted Feat. Only intelligent characters of good alignment and the highest moral standards can acquire exalted feats, and only as a gift from powerful agents of good—deities, celestials, or similar creatures. These feats are thus supernatural in nature (rather than being extraordinary abilities, as most feats are). A character must have the DM’s permission to take an exalted feat. In many cases, a ritual must be performed; often this simply amounts to a character swearing a sacred vow, for example, in the presence of a celestial being. A character who willingly and willfully commits an evil act loses all benefits from all his exalted feats. She regains these benefits if she atones for her violations.
Normal
A nonevil creature that tries to utter the Words of Creation without learning them properly is affected as by a feeblemind spell, while an evil character is struck dead. Fortunately, it is impossible to make someone speak the Words of Creation against his will, because their pronunciation is so exacting.
