Uruk K'daai

Fireborn: This creature is immune to the effects of cold weather (not extreme cold as explained in the Dungeon Masters Guide), immune to the poison condition, immune to fire damage, and may interact with Ashsteel Equipment. Furthermore, this creature has advantage against effects that would cause paralysis or stun. Their physical form can also not be changed by magic. Upon reaching 0 hit points, this creature explodes dealing 2d10 fire damage to all creatures within 10ft.

Ashsteel Weapons: This creature is proficient with all weapons and any weapons or ammunition owned tend to be Ashsteel. Sample Weapons are included in the actions.

One with Fire: This creature can cause metal weapons to deal an additional 1d6 fire damage. Ashsteal weapons deal a 1d8 additional fire damage instead. (Usually either an axe, a sword and whip, or a crossbow)

Multi-Lingual: All soldiers of Uruk are expected to know a number of languages, the standard Duergar commoner would know dwarvish and maybe 1 more.

Fire Form: (Bonus Action) The Uruk K'daai can move through a space as narrow as 1 inch wide without squeezing. A creature that touches the elemental or hits it with a melee attack while within 5 ft. of it takes 5 (1d10) fire damage. In addition, the elemental can enter a hostile creature's space and stop there. The first time it enters a creature's space on a turn, that creature takes 5 (1d10) fire damage and catches fire; until someone takes an action to douse the fire, the creature takes 5 (1d10) fire damage at the start of each of its turns.

Multi-Attack: The Uruk K'daai may make 2 weapon attacks.

Heat Metal: The Uruk K'daai can heat 1 metal object it can touch, making it glow white-hot briefly. Any creature in physical contact with the object takes 2d6 fire damage. If the metal is on a creature, the creature and Uruk Infernal Guard make a contesting dexterity saving throw and check respectively.
