Tempest Sorcery

Your innate magic was granted to you by an Elder Tempest.

One With the Storm

1st-Level Tempest Sorcery feature

You gain resistance against lightning and thunder damage. You also gain access to the gust cantrip, it does not count against the number of cantrips you know. 

Tempestuous Spells

1st-level Tempest Sorcery feature

You learn additional spells when you reach certain levels in this class, as shown on the Tempest Spells table. Each of these spells counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know.

Storm Soul

6th-Level Tempest Sorcery feature

At 6th level, you gain the ability to be as malleable as the winds. You can enter a creature’s space and stop there. You can move through a space as narrow as 1 inch wide without squeezing, though your speed is halved. You can also harness the winds to fall twice as slow as normal if you wish, you may take 1d6 fall damage for every 20ft you fall instead of every 10ft.

Starting at 10th level, you no longer take fall damage as your gossamer physicality softens the impact. However, you still fall prone and a fall that would have reduced you to 0 hitpoints will knock you unconscious, you can be awoken from this state as if you were asleep.

Fury of the Tempest

6th-Level Tempest Sorcery feature

When you cast a 1st lvl or higher spell that does lightning or thunder damage, you can use a bonus action to spend sorcery points equal to the half the spell’s level, rounded down, to roll maximum damage for half of the damage dice in the spell, rounded up (Ex. Rolling 5d6, 3 of those dice are guaranteed sixes). After activating this ability, you may teleport up to 5ft in a crackle of electricity or a boom of thunder. You also gain a flying speed equal to half your walking speed until the end of your turn; if you already have a flying speed, it is increased by half. You may use this ability a number of times equal to your Charisma modifier. You regain all uses of this ability after a short rest.

Starting at 10th level, the range of your teleportation increases to 10ft and your flying speed equals your walking speed (if you already, have one then it's doubled).

Stormy Rebuke

14th-Level Tempest Sorcery feature

Starting at 14th level, when you are hit by an attack, you can use your reaction to deal lightning or thunder damage to the attacker if they are within 30ft of you. The damage equals your sorcerer level.

Stormy Shock: After using this ability, you may spend a sorcery point to force the attacker to make a Constitution saving throw against your sorcerer spell save DC. You may spend an additional 2 sorcery points to give them disadvantage on the save. On a failed save, the attacker is stunned until the end of their next turn.

You may use Stormy Shock a number of times equal to your Charisma modifier. You regain all uses of this ability after a long rest. 

Reading the Tempest

14th-Level Tempest Sorcery feature

You have gained a deeper connection to the wild nature of tempests. You gain knowledge of the following weather events within 10 miles of yourself.
- You can tell where lightning will strike during a storm a minute before it does.
- You can predict how strongly and in which directions the winds will blow within the next 24 hours (which can help you predict tornadoes).
- You can sense any oncoming hurricanes a week before they arrive, and you know their severity.
- You can tell what levels of precipitation an area will get 2 weeks in advance. 

Stormborn

18th-Level Tempest Sorcery feature

You have become finely attuned to the aspects of storms. You gain a flying speed of 30ft (if you already have a flying speed, it is increased by this amount), you are immune to lightning and thunder damage, you have advantage on any saving throw caused by winds, and you are not affected by obscured vision caused by being in a storm. 

In the Eye of the Tempest

18th-Level Tempest Sorcery feature

Starting at 18th level, as an action once per long rest, you can create a storm around you with a radius of 50ft for 1 minute. The storm moves with you. Starting next turn, you may increase or decrease the radius by 10ft at the start of your turn, up to a maximum of 90ft and down to a minimum of 10ft. A larger storm covers more area, but a smaller storm is more concentrated. Heavy precipitation in the form of either rain or snow falls there, causing the area to be lightly obscured. The rain extinguishes open non-magical flames and imposes disadvantage on Wisdom (Perception) checks that rely on hearing. In addition, strong winds swirl in the area covered by the storm. A creature must spend an extra 5ft of movement for every 5ft they try to move towards you. Creatures have disadvantage on ranged attack rolls against you. The winds extinguish open non-magical flames and disperse fog.

When a hostile creature enters the radius of the storm for the first time in a round or starts their turn there, they must make a Dexterity saving throw against your sorcerer spell save DC. If the storm is 20ft or smaller they take 4d6 lightning and 3d8 thunder damage on a failed save, or half as much damage on a successful one. If the storm is 30ft or larger the damage is decreased to 3d6 lightning and 2d8 thunder damage. If the storm is 70ft or larger the damage is decreased to 2d6 lightning and 1d8 thunder damage. If a creature is within 5ft of you, they fail the save automatically.
