Oven Golem

While the golem is not inert, it constantly radiates the earthy heat of the hearth. It and creatures within 15 feet of it suffer no ill effects from cold climates, as described in chapter 5 of the Dungeon Master's Guide.

Whenever the golem is subjected to fire damage, it can choose to expend one of its stored ingredient dice to take no damage and instead regain a number of hit points equal to the fire damage dealt.

Ranged Weapon Attack: your Wisdom modifier + PB to hit, range 30/90 ft., one target you can see. Hit: number rolled on expended ingredient dice + PB fire damage.

The golem cooks any number of stored ingredient dice of the same size to transform them into golem-fired goodies, which can be retrieved by any friendly creature within 5 feet of it as an action. A golem-fired goodie is an edible object roughly the size of a bun. It lasts for 24 hours before becoming inedible. When consumed by a creature as an action, a goodie restores a number of hit points equal to your PB + a number rolled on the ingredient die used to create it.

When the golem takes damage as the result of an attack, it can expend one of its stored ingredient dice to create a 20-foot radius sphere of dark smoke centered on itself. The sphere spreads around corners, and its area is heavily obscured. It lasts for 1 minute or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it. If the golem would be reduced to 0 hit points by the damage it takes, it can still choose to use this reaction before falling to 0 hit points.
