Lightning surges through you, while lashing out violently near you and then it slowly converges in front of you. You can start to cast this spell as an action summoning the lightning, then you must spend one more action at your next turn to complete the spell. It can be broken like concetration spells, if it is broken before you succesfully cast it you still loose the spell slot. When you complete the spell, choose up to 6 creatures you can see within range, lightning rages from the convergence and chases them down striking them. The creatures must make a Dexterity saving throw with disadvatage taking 6d10 lightning damage on a fail and half as much damage on a succes.
