Special Traits

  • Ageless. Grootslang cannot suffer from frailty of old age, die from old age, or be aged magically.
  • Magic Resistance. Grootslang has advantage on saving throws made against spells and other magical effects.
  • Serpentine Charge. If Grootslang moves at least 20 feet straight toward a creature and then hits it with a bite or gore attack on the same turn, that target must succeed on a DC 18 Strength saving throw or be knocked prone. If the target is prone, Grootslang can make one constrict attack against it as a bonus action.


  • Bite. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 16 (2d8+7) piercing damage.
  • Gore. Melee Weapon Attack: +10 to hit, reach 10 ft., one prone target. Hit: 18 (2d10+7) piercing damage.
  • Constrict. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 18 (2d10+7) bludgeoning damage, and the target is grappled (escape DC 18). Until this grapple ends, the creature is restrained. The snake can constrict up to 2 targets at the same time.
  • Swallow. Grootslang makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, that creature takes the bite’s damage and is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside Grootslang, and it takes 9 (2d8) bludgeoning damage at the start of each of Grootslang’s turns. If Grootslang takes 30 damage or more on a single turn from a creature inside it, Grootslang must succeed on a DC 18 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of Grootslang. If Grootslang dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 5 feet of movement per round it was swallowed, exiting prone.


The Grootslang is a legendary monster from South Africa, a serpent as massive as it is devious! This monster is said to lair in a diamond-filled cave in Richtersveld called the ‘Bottomless Pit’ or the ‘Wonder Hole’, a tunnel to the sea 40 miles away.

This enormous snake is 30 feet long and has a head nearly a foot across. Covetous and greedy, the Grootslang desires fine stones, and often trades the lives of its hapless victims in exchange for valuable precious gems.

Legend has it that the Grootslang is a type of primordial serpent from the beginnings of the world. The gods decreed that the creation of an elephant-sized serpent was a mistake, and so they split the Grootslangs into snakes and elephants— except for the one which escaped.
