The Right of Rituals

You have learned a number of spells that you can cast as rituals. 

• When you choose this feat, you acquire a ritual book holding spells for your class list.
•  You must choose your spells from your class's spell list that, you know, and the spells you choose must have the ritual tag. 
• If you come across a spell in written form, such as a magical spell scroll or a wizard's spellbook, you might be able to add it to your book. The spell must be on the spell list for your class, the spell's level can be no higher than half your level (rounded up), and it must have the ritual tag. The process of copying the spell into your ritual book takes 2 hours per level of the spell, and costs 50 gp per level. The cost represents material components you expend as you experiment with the spell to master it, as well as the fine inks you need to record it.
