Water Magic

Lightning Absorption Orb

3-level Evocation

When a creature in a 30 foot range of you, is damaged by lightning, an orb of water 1 foot in diameter appears near them instead. The sphere has 20 health, and an AC of 12.   When an ability that would deal lightning damage to a target within 10 feet of the sphere, as long as the ability isn't touch, the ability is absorbed by the sphere instead. If the ability is targeted, all the damage the ability would do is absorbed by the sphere. If the ability affects an area, half of the damage the ability would do is absorbed.   The sphere can absorb up to 30 points of lightning damage, if the sphere drops to 0 health, or absorbs more than 30 points of lightning damage, it explodes in a 15-foot-radius dealing half the damage it had absorbed. If the damage by an ability would exceed how much it could absorb, then it only absorbs the amount of damage that it had left to absorb.   On your turn you can move the sphere up to 15 feet as a bonus action, and as an action you can dismiss the sphere. If you used the spell as a reaction, the spell doesn't take concentration as long as you dismiss the sphere as your action at the start of your turn.
At higher levels: When casting this spell at a higher level than 3rd, increase the damage it can absorb by 10. For every third level cast, you can create an additional orb with the normal characteristics of the spell instead.
