Arc Flash

After absorbing too much electricity it now flows through your veins. You can force the energy to bend to your will, as a bonus action you can activate a temporary transformation that lasts for 1 minute. While in this form your veins will glow a bright white and occasionally sparks of electricity will emanate off of you. During this time your speed is doubled, you can treat any 1 on a damage die as a 2 (lightning damage only), and you gain advantage on dexterity saving throws. You can use this ability a number of times per day equal to proficiency modifier.
