Gunnspier Hooked Shortspear (Rare)

On a hit with this weapon, the wielder can forgo dealing damage and attempt to trip the target, in which case the target must succeed on a Strength saving throw or fall prone. The DC is 8 + the wielder's Strength modifier + the wielder's proficiency bonus.

"Stab, bang, hope." If consulted, these are the instructions any kobold will give on using a gunnspier. With a lengthy reload time and complete lack of accuracy, this matchlock-augmented polearm is usable at only one range: point blank. It also comes with a lovely ribbon and a neat basket to hold all your spare shot. Cute. You gain a +1 bonus to attack and damage rolls made with this magic weapon.

Point Blank Shot: When you hit a target with an attack using a loaded gunnspier, you can use a bonus action to pull the trigger, firing a plum-sized leaden ball at the target. The attack deals an additional 2d8 bludgeoning damage. As an action, you can reload the gunnspier.

Backfire: When you use Point Blank Shot and roll an 8 on both of the additional bludgeoning damage dice, the gunnspier backfires. Each creature within 10 feet of you (including you) must succeed on a DC 15 Dexterity saving throw or take 4d6 piercing damage as shrapnel erupts from the weapon.

Light: A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
