Apotheosis

You channel your power to approximate divinity. Your body becomes infused with a divine light. You radiate sunlight in a 60 foot radius which dispels all magical darkness. You gain resistance to radiant or necrotic damage (your choice). Your Strength, Constitution, or Dexterity score increases by 2 by up to a maximum of 30 for the duration of the spell (your choice). You may then choose one of the following:

• Whenever you cast a spell, you may use a spell slot that is one level lower than the spell's base level. If the spell is of 1st level, you may cast it for free. Casting a spell at its normal level counts as upcasting it.
• Your spell save DC and Spell attack bonus increase by 2.
• If you cast a leveled spell, you may cast a cantrip as a bonus action.
