I like weapons that deal mutliple dice damage. let’s make that happen in DnD.

Magic Weapon

3rd-level transmutation

Casting Time:1 bonus action
Range:Touch
Components:V, S
Duration:Concentration, up to 1 hour

You touch a magic weapon. Until the spell ends, roll the weapons damage dice twice when you attack and deal damage.

At Higher Levels: When you use a spell slot of 7th level or higher, tripple the weapons damage dice when you attack and deal damage.
