The Lord Of The Tempest

Gweniol is the God Of Winds And Waves. They are mostly favoured in the coastal regions by sailors, pirates and fisherfolk alike. Like all the gods, Gweniol appears however the viewer perceives them; some might see a lady, wrapped in swathes of blue fabric, billowing in the wind, some might see a strong man with a trident and some might even see a serpentine dragon with storms in its eyes.

This is a patron I made for a homebrew game, but you are welcome to use it!

Child Of Sea And Storm

Starting at 1st level, the Lord Of The Tempest bestows upon you the ability to swim as fast as you can walk and breathe underwater.

Tentacle Of The Deep

At 1st level, you can magically summon a spectral tentacle that strikes at your foes. As a bonus action, you create a 10-foot-long tentacle at a point you can see within 60 feet of you. The tentacle lasts for 1 minute or until you use this feature to create another tentacle.

When you create the tentacle, you can make a melee spell attack against one creature within 10 feet of it. On a hit, the target takes 1d8 cold damage, and its speed is reduced by 10 feet until the start of your next turn. When you reach 10th level in this class, the damage increases to 2d8.

As a bonus action on your turn, you can move the tentacle up to 30 feet and repeat the attack .

You can summon the tentacle a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

 

Storm Ward

At 6th level, you learn to magically ward yourself against attack and to turn an enemy’s failed strike into good luck for yourself. You become surrounded by storm clouds. When a creature makes an attack roll against you, you can use your reaction to impose disadvantage on that roll. If the attack misses you, your next attack roll against the creature has advantage if you make it before the end of your next turn. This attack does an extra [roll]1d4[/roll] of lightning damage.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Flight Of The Storm

At 10th level, once per short rest, you can spend a bonus action to gain a flying speed of 60ft. for 5 minutes. You can then, once per round on subsequent rounds, spend a bonus action to cast call lightning at your highest level without expending a spell slot, or you can spend a reaction to impose disadvantage on an enemy's attack against an ally within 30ft. by raining really hard on them.

Fathomless Plunge

When you reach 14th level, you can magically open temporary conduits to watery destinations. As an action, you can teleport yourself and up to five other willing creatures that you can see within 30 feet of you. Amid a whirl of tentacles, you all vanish and then reappear up to 1 mile away in a body of water you've seen (pond size or larger) or within 30 feet of it, each of you appearing in an unoccupied space within 30 feet of the others.

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