SPECIAL TRAITS

  • False Appearance. While the oaken sentinel remains motionless, it is indistinguishable from an ordinary oak tree.
  • Grasping Branches. The oaken sentinel can have up to six Grasping Branches at a time. Each Grasping Branch can be attacked (AC 16; 25 hp; vulnerability to lightning damage; immunity to poison and psychic damage). Destroying a Grasping Branch deals no damage to the oaken sentinel, which can extend a replacement branch on its next turn. A Grasping Branch can also be broken if a creature takes an action and succeeds on a DC 16 Strength check against it.

ACTIONS

  • Multiattack. The oaken sentinel makes three Grasping Branch or Rock attacks. It can replace one attack with a use of Fling.
  • Grasping Branch. Melee Weapon Attack: +10 to hit, reach 50 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage, and the target is grappled (escape DC 16). Until the grapple ends, the target is restrained and takes 4 (1d8) bludgeoning damage at the start of each of its turns, and the sentinel can’t use the same Grasping Branch on another target.
  • Rock. Ranged Weapon Attack: +10 to hit, range 60/240 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage.
  • Fling. One Medium or smaller creature grappled by the oaken sentinel is thrown up to 60 feet in a random direction and forced prone. If a thrown target strikes a solid surface, the target takes 3 (1d6) bludgeoning damage for every 10 feet it was thrown. If the target is thrown at another creature, that creature must succeed on a DC 16 Dexterity saving throw or take the same damage and be forced prone.

ABOUT

An oaken sentinel is an enormous oak tree granted wisdom by druids. Not truly awakened, these trees serve druid circle by, protecting a specific location on behalf of the circle, though sometimes they wander. The oaken sentinel waits for trespassers to step below its wide-reaching boughs before striking.

Standing Stones. Adventurers may recognize one common sign of oaken sentinels—piles of rocks that its druidic masters provide. The oaken sentinel hurls these rocks (or sometimes rotting corpses) at ranged assailants and at fleeing trespassers.

Negotiating Passage. Oaken sentinels do not attack if presented with a token from their druidic masters. Similarly, trespassers who can convince the oaken sentinel that their interests align may pass without further incident.

Practically Immobile. While the oaken sentinel can move, it must extricate its thick roots from the ground to do so, a process that limits the tree’s mobility.
