Warlock’s Trumpetbloom

This plant stands taller than an ogre, and it shuffles forward on a thick mass of tangled roots. A wicked-looking stinger, glistening with venom, flicks out of its “mouth” on the end of a whip-like tongue.

Special Traits

  • Alien Mind. A creature who attempts to communicate with the trumpetbloom must succeed on a DC 15 Wisdom saving throw or become frightened for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
  • Magic Resistance. The trumpetbloom has advantage on saving throws against spells and other magical effects.


  • Multiattack. The trumpetbloom makes three attacks: one with its stinger and two with its tendrils.
  • Stinger. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 16 (2d12 + 3) piercing damage, and the target must succeed on a DC 15 Constitution saving throw or become poisoned for 1 minute. The target is paralyzed while poisoned in this way. It can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
  • Tendril. Melee Weapon Attack: +6 to hit, reach 15 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage and the target is grappled (escape DC 14) if it is a Medium or smaller creature. The trumpetbloom has two tendrils, each of which can grapple only one target.


Born for War. Warlock’s trumpetblooms were created by a mage and his cabal through a series of bizarre experiments that involved cross-breeding native jungle orchids and giant carnivorous plants with alien seed pods. The mage supervised the experiments personally, frequently consulting a living brain he kept in a glass cylinder. When the first trumpetblooms were propagated from seedlings, the mages were astounded at how quickly the plants grew and subsequently reproduced. An unstoppable army was within their grasp-or so they believed. The mages’ optimism proved misguided when the trumpetblooms broke free of the glasshouses and attacked their masters.

Aggressive Carnivores. Warlock’s trumpetblooms are aggressive and intelligent plant creatures that seek to spread their seed pods throughout the jungle and beyond. Trumpetblooms are carnivores, feeding on the small deer, giant insects, and snakes that live in the jungle. They happily devour humanoid flesh when available, using their roots to soak up the nutrients from a decomposing corpse.
