Stormcaller

Stormcallers exist all across the world, existing atop high mountains in intricate monasteries where books and knowledge can be found around every corner. They are knowledge seekers. They have a natural affinity for the powers of lightning and thunder, calling upon the storm to aid them.

Storm's Call

Beginning when you select this school at 2nd level, your affinity with the powers of the storm empower your spells related to it. Whenever you cast a spell that does either lightning or thunder damage, you can use your bonus action to call a lightning bolt to strike a target within 60 feet of you and do extra lightning damage. The target must make a dexterity saving throw against your spell DC and take half damage on a success and full damage on a failure. This damage scales as you level up, as shown below:

1. level 2: 1d6
2. level 5: 2d6
3. level 7: 2d8
4. level 9: 3d8
5. level 11: 2d10
6. level 13: 3d10
7. level 15: 2d12
8. level 18: 3d12

You can do this a number of times equal to your intelligence modifier, you regain all expended uses after a long rest.

Lightning Fast Casting

Starting at 6th level, your body and mind can flow as quickly as electricity, giving the ability to cast spells faster than normal. When you cast a spell, you can expend a spell slot of the same level of the casted spell, this spell can then be cast as a bonus action instead of an action.

Electrified Form

Beginning at 10th level, you can summon the powers of the storm, a lightning bolt rains from the sky, even on sunny days, and coalesces in your body, empowering your form. You use your bonus action to gain temporary hit points equal to your class level multiplied by your intelligence modifier, all damaging spells you cast do extra either lightning or thunder (your choice) damage equal to your intelligence modifier, and resistance to lightning and thunder damage, this lasts for one minute.

You can use this feature a number of times equal to half your constitution modifier (rounded up), and gain all expended uses after a long rest.

Amped Casting

Starting at 14th level, you can call upon the energy that the storm provides to amp your spells to guarantee your success. While in your Electrified Form, when you cast a damaging spell that does either lightning or thunder damage, should the spell miss or the target(s) make the required save, you can use your reaction to cause the target(s) to fail or the spell to hit.
