The Dragonbolt

 You study the teachings and magic of a group of desert-dwelling warriors that worshiped an Ancient Blue Dragon. You harness these powers to empower you and your weapons and debuff your enemies marking them for thunderous lightning strikes.

 

Lightning Imbuement

At 3rd level, once per short or long rest, you may touch one melee weapon without the heavy property to imbue it with a bolt of lightning. While you are wielding the weapon it gains the following benefits:

-The weapon becomes a +1 magic weapon and deals lightning damage in addition to its current damage type.
-The weapon gains reach and finesse if it does not already have them.

Electrical Enhancement

At 3rd level 2+ your proficiency bonus times per day you can use a bonus action to become empowered with arcs of lightning for 10 minutes and gain the following benefits:

-Your movement speed increases by 10 feet.
-When you hit a target with a lightning-imbued weapon while under this effect that target is electrified until the start of your next turn. Electrified targets are slowed by 10 feet.
-You may use your bonus action to raise your imbued weapon into the air to call down bolts of lightning that deal 1d8 lightning damage to all electrified enemies.

Arcs Unleashed

At 7th level, you gain the ability to extend your weapon's range further with lightning arcs. Once per turn when you take the attack action on your turn with a weapon you imbued with lightning you can change one of your attacks into either a 20-foot cone or a 30-foot line originating from your space. This attack counts as a single melee weapon attack against all targets in the area.

Amperage Scaling

At 10th level your training with the blue dragon's electrical power causes your lighting to pack more of a punch, giving you the following benefits:

-All of your lightning-imbued weapons are now +2 magic weapons while you are wielding them if they are not already +2 or higher magic weapons.
-Your movement speed while under the effect of Electrical Enhancement is increased by an additional 10 feet
-Electrified enemies are slowed by an additional 10 feet, take an additional 1d8 damage from the bonus action bolt of lightning and lose any resistance to lightning damage

Thunderous Entrance/Exit

At 15th level, proficiency bonus times per day, you may use an action to teleport up to 60 feet to an unoccupied space. Chose one point at the start or end of the teleport. In a 10-foot radius around that point, all creatures of your choice must succeed a DC 18 dexterity saving throw or take 3d8 lightning damage and become electrified until the start of your next turn. On a successful save, they only take half damage but are still electrified.

Lightning Surge

At 18th level once per turn for a minute after you use your Action Surge you may paralyze one electrified target until the end of your next turn.
