You are able to cast a 2nd-level enhancing spell as a ritual.
Prerequisite: Caster Level 12th.
Twice per day, you can cast a single 2nd-level enhancing spell (that neither deals or heals damage nor increases or decreases size) as a ritual spell. The casting time of the ritual spell increases to 10 minutes, the duration of the spell increases by 1 step (1 round > 1 round/level > 1 minute/level > 10 minutes/level) to a maximum of 10 minutes per caster level, and removes the MP cost from casting the spell. This does not work with other metamagic feats or class features, however.
