Ritualist

Ritualists specialize in the occult science and alien mathematics taught by creatures of the Mythos.

Ritualistic Spellcasting (Ex)

A ritualist can cast a spell ritualistically to increase its power, but the spell is slower and less reliable. The ritualist gains a +2 bonus to his caster level and the spell’s save DC increases by 1. The spell’s duration is doubled. Casting a spell this way increases the casting time to 10 minutes.

If the spell usually takes longer than 1 standard action but no more than 30 minutes to cast, it instead takes 1 hour to cast ritualistically. If it normally takes 30 minutes or longer to cast, it takes twice as long to cast ritualistically. To complete the ritual, the ritualist must succeed at a Profession (Yog-Sothothery philosopher) check against DC 10 + twice spell’s level or a Spellcraft check against DC 15 + twice spell’s level. Failure ruins the spell, wasting the spell slot with no effect. The ritualistic spell requires a written copy of the spell (such as your spellbook) as an additional focus component.

This ability replaces arcane school.

Swift Inscriptions (Ex)

A ritualist reduces the casting time of any ritual (but not ritualistic spellcasting) by half. He can cast any glyph, rune, or symbol spell in 1 round. Casting a spell faster with this ability is taxing and gives the ritualist the fatigued condition.

Scroll Mastery (Ex)

At 8th level, a ritualist uses his own caster level and save DC for any scroll he casts if it is higher than the scroll’s. To do so, he doubles the scroll’s casting time (minimum 1 round) and must succeed at a Profession (Yog-Sothothery philosopher) check against DC 10 + twice spell level or a Spellcraft check against DC 15 + twice spell level. If he fails, a mishap occurs automatically.
