  • Siege Monster. The katari deals double damage to objects and structures.


  • Multiattack. The katari makes one attack with its bite and two Grabbing Claw attacks.
  • Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 24 (4d8 + 6) piercing damage and the target is swallowed if it is a Medium or smaller creature. A swallowed creature is blinded and restrained, has total cover against attacks and other effects outside the katari, and takes 10 (3d6) acid damage at the start of each of the katari’s turns. The katari’s gullet can hold up to two creatures at a time. If the katari takes 20 damage or more on a single turn from a creature inside it, the katari must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, each of which falls prone in a space within 10 feet of the katari. If the katari dies, any swallowed creature is no longer restrained by it and can escape from the corpse using 10 feet of movement, exiting prone.
  • Grabbing Claw. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage plus 11 (2d10) necrotic damage. If the target is a creature, the katari can pull the target up to 10 feet toward itself, and the target is grappled (escape DC 10). The katari has two claws. While a claw grapples a target, the claw can attack only that target.
  • Animate Lesser Katari (1/Day). The katari magically animates one or two trees it can see within 60 feet of it. These trees have the same statistics as a lesser katari. A lesser katari acts as an ally of the greater katari. The lesser katari remains animate for 1 day or until it dies; until the greater katari dies or is more than 120 feet from the lesser katari; or until the greater katari takes a bonus action to turn it back into an inanimate tree. The tree then takes root if possible.


  • Deadly Reach. In response to a creature entering a space within 15 feet of it, the katari makes one Grabbing Claw attack against that creature.
  • Unnerving Mask. When a creature the katari can see starts its turn within 30 feet of it, the katari can create display the pained faces of those it has consumed or plans to consume. If the creature can see the katari, it must succeed on a DC 17 Wisdom saving throw or be frightened until the end of its turn.


What you took for a tree suddenly opens its eyes to reveal a menacing, demonic face! Katari are the suicidal souls released from their prisons to wreak havoc on the world above. Lesser katari are created by greater katari, who are summoned with specific incantations from the Woe Wood to attack foes. They are particularly good at reducing buildings to rubble, and greater katari specialize in snatching foes hiding within them. A typical attack involves a greater katari animating lesser katari and then gradually increasing its attacks until it can level a building, eating everything within. It enjoys torturing its foes and will not hesitate to display faces on its surface of the damned souls it has consumed, or even those it hasn’t yet but plans to.
