The Relentless Storm

The crack of thunder and boom of lightning herald the Relentless Storm, a being of immense power and strength that invokes the tempest wherever they tread. With them as your patron, you can channel this raw, powerful energy to demolish your foes, as well as the structures they hide behind. With the strength of the storm, you leave nothing but rubble and debris behind.

Lightning Reflexes

At 6th Level, you can move with quick bursts of agility when in danger. When you would be subjected to an effect that targets an area, you can use your reaction to move up to half your speed. If at the end of the movement you are outside of the targeted area, you are unaffected by the triggering effect.

Once you use this feature, you can't do so again until you finish a short or long rest.

Expanded Spell List

The Relentless Storm lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Relentless Storm Expanded Spells

Spell Level	Spells
1st	fog cloud, thunderwave
2nd	gust of wind, warding wind
3rd	lightning bolt, wind wall
4th	ice storm, storm sphere
5th	cone of cold, control winds

Sky Splitter

Starting at 1st level, you can call down a bolt of lightning to both empower you and strike back your foes. As a bonus action on your turn, you can choose a point within 60ft of you, which begins to spark with energy. At the start of your next turn a blast of lightning strikes down, causing a 10ft radius sphere to erupt centered on that point. Hostile creatures inside the sphere must make a Strength Saving Throw against your Warlock Spell Save DC, being pushed 10ft directly away from the center of the sphere on a failed save. Additionally, creatures inside the sphere when the lightning strikes cannot take reactions until the start of your next turn.

If you are inside the sphere when the lightning strikes, your patron's strength shields you. You gain temporary hit points equal to your 1d12 + Charisma modifier + half your Warlock level. These temporary hit points last for 1 minute.

The radius of the sphere increases as you gain levels in this class; becoming a 15ft radius at 5th level, and a 20ft radius at 9th.

Once you use this feature, you can't do so again until you finish a short or long rest.

Storm's Blessings

Also at 1st level, your patron grants you some minor boons. You learn the gust cantrip, and can speak, read, and write Auran. You're also naturally adapted to strong wind and heavy precipitation as described in the DMG.

Rolling Thunder

At 10th level, the power of the storm guides you through your steps, allowing you to stand firm against the world. You can't suffer disadvantage on Strength or Dexterity Saving throws while you're not unconscious or incapacitated. Additionally, you can gain resistance to lightning and thunder damage.

Thundercrash

At 14th level, you fully embrace the storm. As an Action on your turn, you can launch into the air, vanishing from sight. At the start of your next turn, you can crash down on an empty space within 500ft of your original location. Creatures within 20ft of the space you land must make a Dexterity Saving Throw, taking 2d12 lightning and 3d12 thunder damage and are knocked prone on a failed save, or half as much damage and not knocked prone on a success. Creatures with in 1 mile of the space you land can hear the impact.

Non-magical items not being worn or carried and structures take double the damage if in the area.

Once you use this feature, you can't do so again until you finish a long rest.
