The Arboreal Archive is a Level 12 creature, with Armor Class 33 and 230 hit points. The Arboreal Archive is a massive, sentient tree acting as a living repository of ancient history and natural lore.
Tremorsense (Imprecise) 60 feet. Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface. Constant Spells. A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires. Abeyance Rift. If an arboreal archive dies unexpectedly before passing on their knowledge in a succession ritual, the amassed lore within their roots and boughs explodes out in a shock wave that deals 8d10 mental damage to creatures within 30 feet (DC 32 basic Will save) before dissipating; those who fail also fall Prone. Axe Vulnerability. An arboreal archive takes 10 additional damage from axes. Memory Maelstrom (3 actions) (concentrate, incapacitation, mental, nonlethal, primal). The arboreal archive tries to overwhelm foes with a surge of information it has absorbed over its long life. This surge deals 5d6 mental damage to each enemy within 40 feet, who must attempt a DC 32 Will save. Critical Success The creature maintains its composure, takes no damage, and is temporarily immune to Memory Maelstrom for 1 minute. Success The creature is Stunned 1 and takes half damage. Failure The creature takes full damage and is Stunned 3. Critical Failure The creature takes double damage, is Confused for 2d4 rounds, and is stunned 3. Improved Knockdown (free action). Trigger The monster's last action was a successful Strike that lists Improved Knockdown in its damage entry. Effect The monster attempts to Trip the creature as a free action. This attempt neither applies nor counts toward the monster's multiple attack penalty.
