The Wood Guardian is originally planted at the base of a large dead tree, surrounded by roaming Wood Saplings. To protect itself, the guardian forces spiked roots from within the ground to impale the attacker when within range, while the Wood Saplings move in on the player as a distraction.
After sustaining enough damage, the guardian looses itself from the base of the tree and attacks the protagonist by slashing, stomping, and unleashing homing spiked roots from underground.
