[Monster Hunting - Mecha Koboldzilla] Flaymefroyer (Patreon)

Wondrous item, very rare (requires attunement)

Kobold ingenuity is excellent, but the execution can be somewhat lacking. Luckily, the original prototype of this flame-filled backpack has undergone some extensive upgrades; it now boasts a nigh-on indestructible braided brass hose and can burn much hotter.

Worn like a backpack, this item 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:

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

Dragon’s Breath. As an action while holding the flaymefrower’s maw, you can 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 20-foot line that is 5 feet wide (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 or line increases by 5 feet or 20 feet, respectively, for each additional charge expended.

Each creature in the area must make a DC 16 Dexterity saving throw. A creature takes 4d6 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.

Coldfire Flame. As a bonus action, you can twist the dragon’s maw 180 degrees, causing the flame to burn blue and deal cold damage instead of fire damage. This change lasts until you use a bonus action to turn it back.
