Arcane Strike

The next time you hit a creature with a melee weapon attack before this spell ends, the weapon gleams with arcane energy as you strike. The weapon is considered magical if it isn't already, and the attack deals extra damage equal to your spellcasting modifier as Force damage.

The spell’s damage increases by 1d8 when you reach 5th level (1d8 + your spellcasting modifier), 11th level (2d8 + your spellcasting modifier), and 17th level (3d8 + your spellcasting modifier).
