Ritual Casting

You can decipher and perform arcane rituals as long as their level does not exceed your skill rank. You must also have Int of at least (7+level), although untrained or low-Int characters can still assist others in ritual magic as appropriate. This skill may not need to be actively checked unless attempting to master or use an unfamiliar ritual, or cast in a contested or stressful situation.
