Volting Ehco

Lightning springs from your finger, as you point to an object or creature you see within range. The target must make a Dexterity Saving Throw.
On a fail the target takes 4d8 lightning damage, can't take reactions until the start of its next turn and has to make Dexterity Saving Throws at the start of their next turn or be paralyzed for that turn only.
On a success the target takes half damage and nothing else happens.
The Target has disadvantage on the Saving Throw if the target is wearing armor made of metal or is in contact with any form of liquid.

The spell's damage increases by 1d8 when cast at higher levels along with Targets chosen.
