Coal Salamander

Coal Form. The coal salamander is normally found in its fossilized coal form. It takes the appearance of a small lump of blackened fossil that glimmers with a coal like sheen. In this form it is invulnerable and cannot be destroyed except with a Wish spell. The coal salamander can be awakened from this form once a week after it is placed in a live fire and fed at least five spell levels. Awakening the coal salamander takes an action. 

Illumination. The coal salamandner sheds bright light in a 30-foot radius and dim light in an additional 30 feet.

Water Susceptibility. For every 5 feet the coal salamander moves in water, or for every gallon of water splashed on it, it takes 1 cold damage.

No Attack. Due to the coal salamander's tiny form, it has no melee attack or means of physically attacking a foe.

Scorching Ray. Ranged Spell Attack: +9 to hit, reach 120 ft., up to four  targets. Hit: 7 (2d6) fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns.

Greater Control Flame. As an action the coal salamander can control or expand any source of flame, smothering a raging inferno or turning a torch into a raging wall of fire. Either end an immediate fire effect within 30 ft or use a fire to cast Wall of Fire at Spell Level 6.
