Destiny Shock

You fire small bolts of electricity from your fingertips. As they impact, at first it feels like a small shock that hurts, however after about a second, the small bolts grow into nearly 50,000 volts of straight electricity running throughout the targets body.  The target takes 2d10 lightning damage and must make a constitution saving throw. 

If the target fails the saving throw they are stunned until the end of their next turn. If they fail by 5 or more, not only are they stunned but the shock forces them to drop their weapons currently in hand (if any at all). Additionally if they fail the save at all, they have trouble functioning normally without shaking for the next 24 hours. 

Upon a success the target is not stunned.
