Bucky Blunderbuss

"BUCKY" is etched on the barrel. When shot covers 15ft cone area. Those in area make a
DC16 Dex save. On fail, 3D8 piercing damage,
1/2 for success. Every time when used, wielder rolls D20, on a roll of 4 or less takes 3D8 fire damage - no save. Gun then explodes in 5ft radius - same Dex save/damage as normal for those in radius. Requires one action to reload - custom ammo can be made at DM discretion.
