Homebrew Firenewt Species Details
Originally from the Elemental Plane of Fire, firenewts can be found on the Material Plane near hot springs and volcanoes. These amphibians need hot water to live, becoming sluggish after spending a week away from a source of moist heat. Firenewts therefore delve for sources of heat in the earth, and a firenewt lair features a network of channels and sluices to circulate hot liquid through the area.

Spit Fire
When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of fire in either a 15-foot Cone or a 30-foot Line that is 5 feet wide (choose the shape each time). Each creature in that area must make a Dexterity saving throw (DC 8 plus your Constitution modifier and Proficiency Bonus). On a failed save, a creature takes 1d10 fire damage. On a successful save, a creature takes half as much damage. This damage increases by 1d10 when you reach character levels 5 (2d10), 11 (3d10), and 17 (4d10).
You can use Spit Fire a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
