Expelliarmus

Using an Arcane Focus, the caster conjures a bolt of crimson red lightning, striking a single target within 60ft, dealing 4d6 lightning damage. The victims weapon is also expelled from their grip, landing 20ft away. The target of the spell is also stunned. On a successful STR saving throw, the target only suffers damage without the effects of being stunned or weapon loss.
This spell requires “expelliarmus” to be said, and for the user to focus on the victim.
