Dragonscale Equipment. The dragon warrior's armor and longsword are part of its body, formed from its own scales.
 Damage to dragonscale equipment does not affect the dragon warrior's own hit points. A dragon warrior can repair its own dragonscale items by spending a Hit Die at the end of a Short Rest; the warrior does not regain hit points from the spent Hit Die, but its dragonscale items are fully repaired and maintained. If the dragon warrior's dragonscale armor or dragonscale longsword are lost or destroyed (see Dust to Dust), the dragon warrior can grow a replacement after finishing a Long Rest by spending one Hit Die for a new sword, two Hit Dice for new armor, or three Hit Dice for both.

Dragonscale Weapon Master. The red dragon warrior deals 3 (1d6) extra damage when it hits with a dragonscale weapon (included in the attack).

Dust to Dust. If the dragon warrior dies, its body and dragonscale equipment immediately crumbles to dust. If any part of its body, including an item of dragonscale equipment, is separated from the dragon warrior for more than 1 minute it will also crumble into dust.

Multiattack. The dragon warrior makes two melee attacks.

Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 12 (1d8 + 1d6 + 4) slashing damage plus 5 (2d4) fire damage, or 13 (1d10 + 1d6 + 4) slashing damage plus 5 (2d4) fire damage if used with two hands.

Counterstrike. If an opponent the dragon warrior can see makes a melee attack against it while the dragon warrior is wielding a melee weapon, the dragon warrior ripostes that attack by using a bonus action or action from its next turn to make a melee attack with that weapon. In addition to the attack's normal effects, if the dragon warrior's melee attack roll is higher than its opponent's melee attack roll or a critical hit, the opponent's attack misses and does no damage.
 If the dragon warrior counterstrikes with an action that makes more than one attack, such as Multiattack, the action's first melee attack occurs on its reaction when it ripostes, and the warrior's remaining melee attacks occur on its next turn.
