False Appearance.

While motionless indistinguishable from ordinary oak tree.

Grasping Branches.

Can have up to six Grasping Branches at a time. Each Grasping Branch can be attacked (AC 16; 25 hp; vulnerability to lightning; immunity to poison and psychic). 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 Str check vs. it.
