This type of spell uses arcane symbols either created by [Energy] or drawn in advance and empowered with [energy]. The relevant ability score for Ritual Arts is Intelligence, and perform requirements are met with the Ritual Arts skill.
Some Ritual Art spells require sealing slots to be used on the creature's body. A creature's body, regardless of its size, holds 6 seal slots. A seal slot applied by a spell is freed when the seal's duration expires, it is dismissed or broken. Other Ritual Art spells require a seal to be crafted in advance. The amount of time crafting such a seal requires usually depends on the complexity of the seal: 1 round (D-Class or lower), 5 rounds (C-Class), 1 minute (B-Class), 5 minutes (A-Class), 10 minutes (S-Class and Super S-Class), and 30 minutes (Epic). Some seals may take more or less time to craft than the number listed above.
A character without the Sealweaver feat or who is not at least 12th level with 12 or more ranks in the Ritual Arts skill suffers a -8 penalty to Learn checks to learn Ritual Art spells and takes twice the normal amount of time.
Advanced Seals: An advanced seal spell is a subtype of Ritual Art spells and requires the Advanced Seals Proficiency feat to be learned, but not the Sealweaver feat.
