Each time your Proficiency Bonus increases, increase the number of Ritual spells selected through this feature, per the above table. Selected spells are always prepared for you and you can cast them with any spell slots you possess.

Quick Ritual. You can use this feature to cast a prepared Ritual spell using its normal casting time instead of the longer Ritual time. This casting doesn’t expend a spell slot. Once you use this feature, you must finish a Long Rest before you can use it again.

Ritual Learning. 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 prepared rituals. The spell's level can be no higher than half your level (rounded up) and it must have the ritual tag. The process takes 1 hour per level of the spell, and costs 50 gp per level. The cost represents the material components you expend as you experiment with the spell to master it, as well as the fine inks you need to record it.
