Thunderbolt

While most rogues favor stealth and subterfuge, others favor shock and awe. These rogues, charged with elemental lightning, are one such archetype, and surge from one target to the next in a blinding display that leaves survivors dazzled and casualties burned to death.

Lightning Strike

When you take this archetype at 3rd level. You can read, speak, and write Auran and Celestial. You can also use an action to surround yourself with lightning and hurl yourself 15 ft in a straight line with a brilliant flash of light thunderous roar. This movement does not provoke opportunity attacks. All creatures within 5 feet of the line you moved must succeed on a Constitution saving throw (DC-8+ your proficiency bonus + your Constitution modifier) or be blinded and deafened until the end of their next turn. During or after this movement, you can make a weapon attack. If you use your Sneak Attack, the extra damage is lightning instead of the weapon's type. You can use this ability three times, and regain all uses of it after you finish a short rest. At 5th level and again at 9th, 13th, and 17th levels, the maximum distance you can move increases by 5 feet.

Storm Javelin

You gain proficiency in javelins, which have the finesse property when you wield them. You can use an action to create a javelin made from solidified electricity in your empty hand, which disappears after you make an attack with it.

Reverse Charge

Beginning at 9th level whenever you use Uncanny Dodge, you can move 15 feet away from your attacker in a burst of sparks after you take any remaining damage. This movement does not provoke attacks of opportunity

Thunder Child/Flashbulb

Starting at 13th level you gain resistance to lightning, thunder, and falling damage. You can also predict the weather in the next 8 hours with perfect accuracy.

Also at 13th level you can use a bonus action to release accumulated charge in a brilliant burst that scours the eyes of every creature within 15 feet. Those creatures must make a Constitution saving throw (DC-8 your proficiency bonus + your Constitution modifier) On a failed save, a creature is blinded until the start of its next turn. You cannot use this feature if you used Lightning Strike during your turn, and if you use this feature, you cannot use Lightning Strike until your next turn.

From A Clear Sky

Starting at 17th level you can travel vast distances as a thunderbolt. You can teleport to any point you can see by transforming into a bolt of lightning that streaks into the air. only to come crashing down at the point of your choice with a mighty flash and roar of thunder that all creatures within 5 miles can see and hear. All creatures and objects within 5 feet of the point you land take 1d6 lightning and 1d6 thunder damage. To use this feature, both you and the point you choose must be outdoors.
