Tendrils of Lightning

for the duration, you can use your bonus action to cause tendrils of lightning to spring from your fingers, into creatures you can see within range. that creature must make a constitution saving throw against your spell save DC, taking 2d8 lightning damage on a failed save, or half as much on a successful one. additionally, on a failed save, you can choose one of the following effects to happen:

• the target must make a strength saving throw, being pushed back 20 feet on a failed save, or 10 feet on a successful one.
• the target must make another constitution saving throw, taking another 1d10 lightning damage on a failed save.
• until the start of your next turn, the lightning continues to spew from your finger tips. for this round,their is a line from you to the creature you targeted that is 5 feet wide. when a creature ends their turn in it or enters it for the first time, they must make a constitution saving throw, taking lightning damage equal to your spellcasting ability modifier on a failed save, or half as much on a successful one.
• you make a check using your spellcasting ability, contested against the target's Dexterity (acrobatics). if you win, the creature is flung up to 20 feet in any direction of your choice.
• the target must make a constitution saving throw with an advantage. on a failure, the creature is stunned for a round.
