Traits and Actions

Fire Absorption

Trait
Damage Immunity Custom
Whenever the slagling is subjected to fire damage, it takes no damage and instead regains a number of hit points equal to the fire damage dealt.

Unstable Core

Trait Custom
Unstable Core Death Burst Custom
Saving Throws Rule
When the slagling drops to 0 hit points, its core ruptures. Each creature within 10 feet of it makes a DC 13 Dexterity saving throw, taking 2d6 fire damage on a failure, or half as much on a success. The slagling is then destroyed.

Slag Trail

Trait Custom
Slag Trail Hazard Custom
At the end of each of its turns, the slagling leaves a 5-foot square of hot slag in a space it occupied. A creature that enters that square for the first time on a turn or starts its turn there takes 1 fire damage. The slag cools and vanishes after 1 minute.

Slam

Action
Melee Attack Custom
Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage plus 3 (1d6) fire damage.

Cinder Spray (Recharge 5-6)

Action Custom
Cinder Spray Custom
Saving Throws Rule
The slagling exhales burning cinders in a 15-foot cone. Each creature in the cone makes a DC 13 Dexterity saving throw, taking 10 (3d6) fire damage on a failure, or half as much on a success.

Running the encounter

Combat Behavior

Tactics

  • Lumbers toward the warmest creature, ignoring fire attacks and soaking them to heal.
  • Uses Cinder Spray when two or more foes cluster in a cone.
  • Dies deliberately in tight corridors to force the Unstable Core save.

Combat Style

Slow, implacable hazard brute that punishes clustering and melee kills.

Morale

Mindless and relentless; it never flees and fights until destroyed.
