Kobbold Flaymefrower (Uncommon)

What could possibly go wrong carrying a portable furnace on your back? Great for keeping weeds in check, the flaymefrower can be dynamically adjusted to spray in a wide cone or a focused line. Just keep an eye on the pressure, as it looks like the rats have been chewing at the intestine hose again. Worn like a backpack or satchel, this patchwork vessel of scrap metal can hold a maximum of 12 charges. Over the course of an hour, you can feed one of the following fuel options into the backpack, causing it to regain expended charges depending on the fuel's quality:

• 1 sp of seasoned wood: 1d4 charges.
• 5 gp of high-quality coal or oil: 1d4 + 3 charges.
• Elemental core of fire, or breath sac of a red, gold, or brass dragon: all expended charges.

Dragon's Breath: While holding the flaymefrower's maw, you can use an action to speak one of the flaymefrower's two command words, expending 1 charge and causing it to spout a gout of flame in a 10-foot cone or a 5-foot-wide, 20-foot-long line (your choice). As part of the same action, you can squeeze the maw, injecting more fuel and spending up to 3 additional charges. The size of the cone increases by 5 feet or the length of the line increases by 20 feet, for each additional charge expended. Each creature in the area must make a DC 13 Dexterity saving throw, taking 2d10 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.

Backfire: When you use Dragon's Breath and roll a total of 19 or higher on the fire damage dice, the flaymefrower backfires. Each creature within 10 feet of you (including you) must succeed on a DC 13 Dexterity saving throw or take 4d6 fire damage as gouts of flame burst from the make-shift hose.
