Hangman Tree
This tree is named for its noose-like vines. Hangman trees are deciduous, resembling thick oaks with few branches and sparse foliage. Knot-like sensory organs are usually located high on the trunk. In the area where the tree's main branches split off, there is an opening which leads to the creature's acid-filled "stomach." The lower trunk has a slash-like opening for the expulsion of indigestible items. Saplings can move at 6 feet an hour, while older trees can move only 2 feet an hour. Their shallow root systems and small number of leaves require them to supplement their diet by direct ingestion of protein, so each tree traps prey. During freezing weather, a taproot is put down and the tree is dormant. A hangman tree can release a hallucinatory perfume at will, and it does so when prey is 30-80 feet away. Those who inhale the perfume believe the hangman tree to be a normal tree, or even a treant, depending on the mood of the tree. Mature and older hangman trees can speak halting Common. The tree attacks by dropping noose-like vines around prey. Although each tree has 1d4+5 appendages, it can control only three of them at any one time. It takes 1d8+12 points of damage to sever a vine; this is in addition to the damage needed to kill the tree. Vines are AC 5, while the main tree is AC 3. When in contact with a victim, the tree inflicts 1-3 points of damage per round as the vine tightens and lifts its prey (1,000-pound limit) to the opening in the upper trunk. This requires four rounds. One attempt at a bend bars/lift gates roll can be made to break free; victims who fail the roll cannot escape. On the fifth round after being picked up, the victim is dropped into the hangman tree's stomach. The victim suffers 3d4 points of acid damage per round until dead, and is then digested. Escape from the stomach is impossible. Many sharp growths surround the top of the opening, they point inward and down. About three man-sized victims can fit in the tree's stomach at one time.
A hangman tree draws power from its environment. It has 5% resistance to magic per decade of age, up to a maximum of 95%. However, the tree is vulnerable to elemental attacks. Lightning that passes its magic resistance inflicts double damage; extreme cold shocks the tree into dormancy until it thaws. Darkness also causes it to slow its activities, so it functions at half efficiency (three attacks per two rounds). Hangman trees have no interest in treasure and, because they move constantly, it is unlikely that treasure would be found near one, although they do expel undigestible items periodically.
