Ryoko's Guide to the Yokai Realms
2-level Abjuration
You attempt to capture and redirect lightning. Make an Arcana check using your spellcasting ability, with a DC equal to half the lightning damage taken. On a failure, you gain resistance to lightning damage until the end of the turn, including against the triggering damage. On a success, you gain immunity to lightning damage until the end of the turn, including against the triggering damage. In addition, if the source of the damage was a spell, the spell’s area stops at you if it is a line, and you can reflect the spell back at the source as though it originated from you, using your spell save DC or spell attack modifier, turning the caster into the target.
When you cast this spell using a spell slot of 3rd level or higher, the casting time of the spell changes to "1 reaction, which you take when a creature within a certain range of you takes lightning damage". This range is 10 feet at 3rd level, and increases by 10 feet for each slot level above 3rd. When you redirect lightning away from a target other than yourself, that creature gains resistance or immunity to lightning damage (on a failure or success, respectively) instead of you.
