Arcane Touch

Your hands are covered in crackling energy. Make a melee spell attack against a creature within your reach. You gain advantage if the target creature is wearing something made of metal or is composed mostly of metal. On a hit, you deal 2d10 lightning damage and the target must make a Constitution saving throw or fall Prone.

At Higher Levels. When you cast this spell by spending Mana points equal to a 2nd-level spell or higher, the damage increases by 1d10 for each level above 1st. When cast as a 5th-level spell or higher, the lightning damage becomes plasma.
