Canister Shot (5e Equipment)

Cost: 10 gp

Typically designed for cannons, though versions could conceivably exist for any ranged siege weapon, canister shot is used to convert a typical anti-materiel siege weapon into an anti-personnel weapon by replacing a single solid projectile with a canister of many smaller projectiles.

A ranged siege weapon that is loaded with a canister shot sprays a 10-foot-cube area within normal range when it attacks. Each creature in the area must succeed on a DC 15 Dexterity saving throw or take the weapon's normal damage.
