Seething Chongtong [CARD] (Patreon)

Weapon (quarterstaff), rare (optional attunement)

A staff that doubles as a firearm, delivering death from afar. This quarterstaff has the Ammunition and Loading properties, and can be loaded with a single crossbow bolt at a time. You gain a +1 bonus to attack and damage rolls made with this magic weapon.

Hand Cannon. If this weapon is loaded, you can make a ranged weapon attack (60/150 ft.) firing a blazing bolt, dealing 1d4 piercing damage and 1d4 fire damage. Proficiency with crossbows or firearms allows you to add your proficiency bonus to the attack roll. After using this feature, until the end of your next turn, melee attacks made with this weapon deal an additional 1d4 fire damage as the barrel remains hot.

Han. Power from suffering. While attuned to this weapon, when you take damage from a creature you can see, you can spend a hit die (no action required) to mark that creature with a deep grudge. For the next minute or until you are knocked unconscious you gain the following benefits:

You have advantage on the first attack you make each turn against the marked creature.

If you use the Hand Cannon feature against the marked creature, you ignore half cover and three quarters cover.

You have advantage on saving throws against being charmed or frightened by the marked creature.

You can use this feature a number of times equal to your Wisdom modifier (minimum of one). You regain all expended uses of it when you finish a long rest.

Though simple in design, the Chontong served as a functional weapon in times of crises and warfare. The ease with which it could be handled allowed it to be used by anybody and everybody, from an able-bodied soldier to an inexperienced villager so long as they could aim the barrel.
