Alchemist's Bubblegun

Weapon (pistol), uncommon

This pistol doesn't fire bullets like a traditional pistol, and as a result it lacks the loading and ammunition properties. Instead, it fires a series of pressurized, acidic bubbles. It can only be fired once per turn. A target takes 2d6 acid damage on a hit, instead of the normal damage for a pistol, and you don't add your ability modifier to the damage roll. When you hit a target in this way, you can choose a second target within 5 feet of the first. If the second target would have also been hit by your attack roll, it takes acid damage equal to half the amount dealt to the first one.

In addition, you can use a bonus action to pour a flask of alchemist's fire, a flask of holy water, a drinkable potion, or a poison (basic poison or injury type only) into the bubblegun, altering the weapon as described below.

• Alchemist's Fire. For the next minute, any target that takes acid damage from the weapon also takes an extra 1d4 fire damage.

• Holy Water. For the next minute, the weapon deals radiant damage instead of acid.

• Potion or Poison. The next attack you make with the weapon applies the effects of the potion or poison to the hit target (without dealing its normal acid damage or affecting neighboring creatures); a willing target can choose to automatically be hit by a potion fired in this way. Hit or miss, the potion or poison is then expended.

Journal entry, Hereten Moon 12, waning;
In my long, long adulthood—made so by alchemy, of course—I've found myself longing for simpler and more joyful pursuits. A stick and hoop, a game of catch...a bubbling toy? And what better way to make a toy than to make it practical in today's dangerous world?
—Supplemental log: I have been told by my great, great, great grandchildren (parents themselves now) that I am wildly off base with my assumptions, and I am no longer allowed to provide toys to their children without first earning their approval. Creative criticism is always valuable.
