The Storm Dragon Domain

You are a follower of the teachings of the Storm Dragon. This religion has strict rules about only using thunder and lightning magic in combat (You will have disadvantage to your spell attacks or your enemies will have advantages on their saves if you use any other type of spell damage) as well as only using conductive materials to wear and use. This allows the storm dragon's power to flow through you readily, having numerous noticeable effects on your body. This religion does not actively seek violence but teaches all followers to accept that violence is a part of the necessary change required to grow. Followers of this religion are required to help developing technology and and growing cities. They love to be surrounded by electrical devices and metals. However they have an aversion to more natural settings and ways of life. Some think that the storm dragon is actually just Talos in disguise trying to reach new followers.

Storm Dragon Apprentice

At 1st level, you gain proficiency with heavy armor as well as a resistance to lightning and thunder damage.

You also generate mild glow around your body as you perform actions and a soft humming noise, this gives you permanent disadvantage on stealth checks or hiding in darkness, even when magically made invisible. This same ability also upsets animals when you're near them them giving you disadvantage on animal handling. However this same ability can be manipulated into an intimidating display allowing you to add your wisdom to your intimidation score.

This glow can be amplified to light up a 30ft sphere around you at will. This will light up to be like day light and then for a further 15ft beyond the sphere it is dim light. This feature however can not remove magical darkness or thick smoke/fog.

Storm Dragon's Sting

Also at 1st level you add your WIS modifier the damage roll of any cantrip or spell you cast as long as it does lightning or thunder damage.

Channel Divinity: Wrath of the Storm Dragon

Starting at 2nd level, you can use your Channel Divinity to wield the power of the Storm Dragon.

When you roll lightning or thunder damage, you can use your Channel Divinity to deal maximum damage, instead of rolling.

Storm Dragon's Bounty

At 6th level, you can use any conductive object as a spell focus. Also once per your proficiency bonus, you can cast a spell without spending a spell slot. This only works with lightning or thunder based spells that are already available to you at the levels you currently cast them. This ability resets after a long rest.

At level 16 you only need a short rest to reset this feature

The highest level spells use up more slots. 2 slots for 7th level, 3 for 8th and 4 slots for a 9th level spell. If used to cast a cantrip or spell that is 1/4th your level rounded down then you may cast it as a bonus action.

Storm Dragon's Lair

At 8th level you gain the ability to, once per long rest, as a bonus action create a 300ft sphere, with you as the center, where static electricity is running wild. Small arcs can be seen everywhere for brief moments, coming and going randomly in every direction. Everyone's hair stands on edge and skin feels the movement of electrical current. This magical sphere manifests instantly and will infuse all lightning and thunder based damages and increase them by 1 of whatever die they use. This damage increase happens for any and all lightning/thunder based damage, regardless of source or target. The storm sphere will move as the caster does, always putting them in the center. This ability does not require concentration and lasts for 1 hour unless the caster chooses to end it sooner. It has the potential to unintentionally ignite any highly flammable substances near by.

At level 15 this ability has unlimited uses and can be turned on and off at will.

Embody The Dragon

At 17th level, you have a flying speed of 60. This is achieved by forming brilliant blue dragon wings from your just behind your back. The wings are translucent, ethereal and size appropriate. When not in use the wings are invisible. Your eyes get a dim white glow and allow you to have dark vision for 300ft. You also become immune to lightning and thunder damage as your skin develops the faint appearance of scales that shimmer in direct light. You find you are now slightly better at everything and wiser.
