Your Dexterity score increases by 1 and your Constitution score increases by 2.

Firenewts reach maturity around age 5 and usually don't live longer than 30 years.

Due to their worship of the ancient primordial Imix, the Prince of Evil Fire, Firenewts are usually neutral evil. Firenewts of other alignments usually leave their community out of fear of persecution.

Firenewts resemble slender humanoids. The stand between 5 and 6 feet tall and weigh about 150 pounds. Your size is Medium.

Your base walking speed is 30 feet.

Firenewts’ signature trades are alchemy and smithing. You gain proficiency with Alchemist’s supplies and Smith’s tools. You also gain the ability to craft a flask of Pyro-paste by providing 1 gp worth of sulfur, mineral salts, and oil and spending an hour of downtime. This paste is used to fuel your Spit Fire trait. Pyro-paste can also be used in the same way that one would use a flask of oil.

You can breath air and water.

You have resistance to fire damage. You also take no damage from lava or other hot liquids.

Firenewts require exposure to hot moisture to survive. If a tenday passses without exposure to an external source of moist heat, such as boiling mud or hot springs, you gain a level of exhaustion. For each additional day you go without, you gain another level of exhaustion. This exhaustion can only be removed by exposure to an external source of moist heat. Once you reach exhaustion level 5, in addition to the normal effects of exhaustion, you enter a hibernation like state. While in this state, you stop gaining additional exhaustion, but you are rendered unconscious until you are submerged in a hot liquid for at least 10 minutes, after which you awaken and your exhaustion is reset to zero. 

You gain proficiency with longswords, pikes, and scimitars.

As an action, you can spit a mote of fire at one creature within 10 feet of you. The creature must make a Dexterity saving throw with a DC equal to 8 + your proficiency bonus + your Constitution modifier. The creature takes 2d6 fire damage on a failed save, or half as much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. You can not use this ability again until you finish a short or long rest, or use your action to ingest a flask of Pyro-paste.

You can speak, read, and write Common, Draconic, and Ignan. Ignan is one of the four dialects of Primordial, allowing you to communicate with speakers of that language and the other dialects.
