Favored Mystery

( Tome of Magic, p. 136)

[General]

The mystery you choose becomes easier to cast.

Prerequisite

Ability to cast mysteries,

Benefit

Choose a mystery you know. You cast that mystery as a supernatural ability instead of a spell-like ability, or as a spell-like ability instead of as a spell. If you choose a mystery that you cast as a supernatural ability, or if you later gain the ability to cast that mystery as a supernatural ability, you gain an extra use of that mystery per day. This feat does not otherwise increase the number of times per day that you can cast the chosen mystery.

Special

You can take this feat multiple times. When you take the feat again, you can choose to affect the same mystery: or a different one.
