Arcane Heart

The spirit of a long deceased wizard latches onto your body fueling you with spellcasting ability. You learn three cantrips, as well as, a number of wizard spells that you can cast. These spells are written in a wizard book you can summon and dismish to a extradimensional space as an action.

• When you choose this feat, you learn three wizard cantrips of your choice. You also acquire a wizard book holding two 1st-level wizard spells of your choice. One of the 1st-level spells you choose, must have the ritual tag and must be cast as a ritual when cast. The second spell you choose can't be at a level higher than half your current level rounded down, and at 4th level and every two levels past 4th you can swap this spell for another wizard spell no higher than half your level rounded down. You are more attuned to this spell allowing you to forgo casting this spell as a ritual if it has the ritual tag, but only once, casting it with its standard casting time instead and regaining this casting feature after you finish a long rest. Your Intelligence determines your spellcasting ability for these spells.
• 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 wizard book. The spell must be on the wizard spell list, the spell's level can be no higher than half your level (rounded up), and it must be a cantrip or have the ritual tag. The process of copying the spell into your wizard book takes 2 hours per level of the spell (1 hour for cantrips), and costs 50 gp per level (30 gp for cantrips). 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.
