Arcane Cannon

You infuse a weapon with the trigger property with magic. The arcane cannon can be used as a spellcasting focus.

The cannon has the following infusion options:

• Flame Cannon. You can use a bonus action to activate the weapon’s flame cannon for 1 minute. When activated and as a bonus action on subsequent turns, you can make the cannon exhale fire in a 15-foot line. Each creature in that area must make a Dexterity saving throw, taking 2d6 fire damage on a failed save or half as much damage on a successful one. The fire ignites any flammable objects in the area that aren’t being worn or carried. Once you activate the flame cannon, you can’t do so again until you finish a long rest or you expend a spell slot to activate it again. If you use a spell slot to activate the flame cannon, the fire damage instead becomes 1d6 + 1d6 per level of the spell slot expended.

• Force Cannon. You can use a bonus action to activate the weapon’s force cannon for 1 minute. When activated and as a bonus action on subsequent turns, you can make a ranged attack with the cannon targeting one creature or object within 120 feet of you. On a hit, the target takes 1d8 force damage, and if the target is a creature, it is pushed up to 5 feet away from you. Once you activate a force cannon, you can’t do so again until you finish a long rest or you expend a spell slot to activate it again. If you use a spell slot to activate the force cannon, the damage instead becomes 1d8 per level of the spell slot expended.

• Specialised Function. If this weapon has the loading property, its normal and long range is doubled. And if the weapon has the reload property, the weapon can be fired two additional times before it needs to be reloaded (e.g. reload [1] becomes reload [3]).
