Salamander

A creature that touches the salamander or hits it with a melee attack while within 5 feet of it takes 7 (2d6) fire damage.

When the salamander hits with a metal melee weapon, it deals an extra 3 (1d6) fire damage (included in the attack).

The salamander makes two attacks: one with its spear and one with its tail.

Melee Weapon Attack: +7 to hit, reach 10 ft.. Hit: 11 (2d6 + 4) bludgeoning plus 7 (2d6) fire damage.
The target is grappled (escape DC 14). Until this grapple ends, the target is restrained, the salamander can automatically hit the target with its tail, and the salamander can't make tail attacks against other targets.

Melee or Ranged Weapon Attack: +7 to hit, reach 5 ft. or range 20/60 ft.. Hit: 11 (2d6 + 4) piercing plus 3 (1d6) fire damage or 13 (2d8 + 4) piercing plus 3 (1d6) fire if used with two hands to make a melee attack.
