Charge Metal

With a word, you infuse electricity into a metal object you can see within range, such as a metal weapon or a suit of heavy or medium metal armor. Any creature in physical contact with the object takes 1d6 lightning damage when you cast the spell. At the start of your turn, a creature touching the object takes the damage again. If a creature is holding or wearing the object and takes the damage from it, the creature must succeed on a constitution saving throw or drop the object if it can. If it doesn't drop the object, it has disadvantage on dexterity saving throws until the start of your next turn.

At higher levels. When you cast this spell using spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st
