Improved Spontaneous Casting
You can cast spells that remove or inflict status ailments spontaneously; doing so expends one channel energy attempt.
Prerequisite: channel energy class feature, spontaneous casting class feature.
Benefit: Your spontaneous casting is expanded to include remove fear, remove blindness/deafness, remove paralysis, remove curse, remove disease and neutralize poison spells if can channel positive energy. Doing so expends one channel energy attempt per spell as well as the appropriate spell level slot. If you are able to channel negative energy, your spontaneous casting is expanded to include: cause fear, blindness/deafness, hold person, contagion, and poison. Doing so expends one use of channel negative energy and the corresponding spell slot.
Normal: You can only spontaneously cast "cure" or "inflict" spells.
I'd figure it would scale with levels as the normal version does; you have to be 7th level to cast neutralize poison. This feat could also be easily avoided with carrying around scrolls of the individual spells, but I wanted to add some flavor and enchance some core abilities.
