Wizards gain the Arcane Tradition feature at 2nd level, and the Inheritant, School of Composition, and School of Divinity are new options for that feature.

Inheritant

Unlike wizard schools, mages that claim the arcane tradition of Inheritants do not choose their path, but instead are chosen by it. Whether by heritage, boon, or an accident of inscrutable fate, such wizards are suffused with magic in every part of their beings and do not learn to cast spells so much as they learn to control the way spells pour out of themselves. Being so close to the source of their arcana, these spellcasters are well-known for the unusual way they contort the magic inside them to unique effect.

Magic Inherent By 2nd level, you have fully awakened to the true power of the magic inside you. You no longer need to provide material components for your wizard spells, unless they have a cost, such as the specially marked sticks, bones, or similar tokens worth at least 25 gold pieces for the augury spell. Additionally, you no longer need a spellbook, instead drawing on magic from within. You can instead commit the current contents of your spellbook and any other spells you learn by gaining wizard levels to memory. When you find a wizard spell of 1st level or higher, you can commit it to memory by taking time to decipher and rehearse it. For each level of the spell, the process takes 2 hours and costs 50 gp. The cost represents research materials you purchase to guide your experimentation. Once you have spent this time and money, you can prepare the spell just like your others.
