A tendriculos can rear up to a height of 15 feet. It weighs about 3,500 pounds.
Animals and other plant creatures are unnerved by the presence of a tendriculos; they avoid it and any place it has been within the last 24 hours.
Prowling deep forests or waiting in vegetated areas (looking like nothing more than a small hillock), a tendriculos attacks savagely, showing no fear. It attempts to swallow as much flesh as it can, as quickly as it can.
To use this ability, a tendriculos must hit a creature at least one size smaller than itself with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the opponent in the following round. A tendriculos can also use its improved grab ability on a tendril attack. If it wins the grapple check, it establishes a hold, picks up the opponent, and transfers it to the mouth as a free action, automatically dealing bite damage.
A tendriculos can try to swallow a grabbed opponent by making a successful grapple check. Once inside the plant’s mass, the opponent must succeed on a DC 20 Fortitude save or be paralyzed for 3d6 rounds by the tendriculos’s digestive juices, taking 2d6 points of acid damage per round. A new save is required each round inside the plant. The save DC is Constitution-based. A swallowed creature that avoids paralysis can climb out of the mass with a successful grapple check. This returns it to the plant’s maw, where another successful grapple check is needed to get free. A swallowed creature can also cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the tendriculos’s interior (AC 14). Once the creature exits, the plant’s regenerative capacity closes the hole; another swallowed opponent must cut its own way out. A Huge tendriculos’s interior can hold 2 Large, 8 Medium, 32 Small, 128 Tiny, or 512 Diminutive or smaller opponents.
Bludgeoning weapons and acid deal normal damage to a tendriculos. A tendriculos that loses part of its body mass can regrow it in 1d6 minutes. Holding the severed portion against the mass enables it to reattach instantly.
