Anti-Magic Pulse Bomb

 This bomb can be retro fitted to have a delayed fuse that can last for up to a minute or explode on impact. Upon exploding, this bomb releases a pulse of disruptive energy in a 10-foot radius. All creatures in the area must succeed on a Constitution saving throw (8+your proficiency bonus+your Dexterity modifier) or be unable to cast spells until the end of their next turn. Additionally, any active spells or magical effects within the radius are suppressed for 1 minute, as if affected by the Antimagic Field spell.
