Electric Propulsion

You channel lightning to shoot yourself along a surface at high speeds, you levitate 5 feet off the ground and can move double the distance of your move speed. Due to the high speeds at which you travel, you will not invoke opportunity attacks when passing enemies.

You may make a reaction to strike an enemy dealing xd4 damage, x being distance fallen divided by 5, for example, if you fall 10 feet and move forward 30 you may deal 8d4 + weapon + proficiency + stealth attack/attack bonuses. (falling will not take movement and will add to the attack power for every 5 ft fallen.)

If you take the reaction attack your movement is stopped instantly, for every 10 ft fallen you receive 1d4 damage, you may make a Dc 18 constitution saving throw, if you succeed you reduce damage by half. Any fall damage reduction feats/abilities take effect as well.
