Electrify Weapon

You pass your hand over a weapon you are holding and imbue it with lightning as sparks of electricity emanate from it as if trying to escape their vessel. As you hit with this weapon, you deal an extra 1d8 Lightning damage, and the target must make a Constitution saving throw. On a failed save, the target's Speed is reduced to 0, and it cannot take Reactions until the end of your next turn.
