Anti-Magic Sling

This item works as a normal sling with the following added effect:

When you see a spellcaster cast a spell that targets a creature within 5ft of you, including yourself, you can use your reaction to attempt to catch the spell and launch it back at the caster. Make a Dexterity Check against the caster's spell DC, on a success you launch the spell back at them, on a failed save nothing happens.
