  • False Appearance. While the hammer holly remains motionless, it is indistinguishable from a normal holly tree.


  • Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 21 (5d6 + 4) bludgeoning damage and target is stunned for 1 round. If the target succeeds on DC 12 Constitution saving throw, it is not stunned.


These holly trees appear as others of their kind: waxy leaves of deep green and clusters of bright red berries. However, these trees respond to the approach of creatures by swinging their branches, clubbing at anything that moves within range of their senses. Victims of a hammer holly lie where they fall, becoming compost to feed the tree.

Experiment Gone Wild. Some scholars believe hammer hollies were magically engineered in Carnessa when the magocracy still thrived. They theorize the trees were early attempts to weaponize plants, acting as a passive security measure for the gardens and grounds of wealthy wizards. Their presence in the Western Wastes is used as proof of the dangers present south of the Wall. Those that hold this position warn that dangerous plants have already migrated north and that more will certainly follow. While they only grow during a mad spring, it is thought that those short periods are enough to allow such plants to continue to spread and that it is only a matter of time before they reach areas where they can thrive longer and become a major menace, such as the Ironcrags, Allain, and even the Arbonesse.

Hammer Holly Wine. Like most hollies, the berries of the hammer holly are toxic. They are not poisonous to dust goblins however, and those humanoids enjoy a fermented beverage brewed from the berries that might generously be called wine. Hammer holly wine is a great delicacy for dust goblins and a rarity considering the difficulty in harvesting the necessary ingredient. Creatures who seek peaceful relations with dust goblins will find their chances greatly increased should they have hammer holly berries to offer in trade or as a bribe. Any creature other than a dust goblin that drinks hammer holly wine is poisoned for 1 hour. A successful DC 12 Constitution saving throw negates the poisoned effect. Each serving beyond the first causes a creature 3 (1d6) points of poison damage and increases the duration of the poisoned condition by an additional hour; a successful save halves the damage and negates the poisoned effect, but the DC for the saving throw increases by 1 for each additional serving drunk.

Incidental Treasure. Items belonging to victims of a hammer holly often linger long after their owners have decomposed. This works to the hammer holly’s advantage as new victims are often lured into range of the tree’s attacks by shiny objects glinting among the tree’s roots.
