Tarry Vine. At the start of a combat, a bloodoak has eight tarry vines attached to it.
Whenever the bloodoak takes 20 or more damage in a single turn, one the tarry vines is severed.
At the start of its turn, the bloodoak grows three tarry vines for each of vines that was severed since its last turn, unless it has taken 5 or more fire damage per severed vine. The bloodoak regains 5 hit points for each vine regrown in this way.
Multiattack. The Bloodoak makes as many Vine attacks as it has tarry vines and one Bite attack.
Vine. Melee Weapon Attack: +11 to hit, reach 30 ft., one target. Hit: 11 (1d6 + 7) bludgeoning damage and the target is grappled (escape DC 16).
At the start of the bloodoak's turn, any Large or smaller creature grappled this way must make a Strength saving throw (DC 16) or be pulled 10 ft towards the bloodoak. A target grappled by one or more vines has disadvantage on this saving throw.
Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 33 (4d12 + 7) piercing damage. Any target that is a Large or smaller is swallowed. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the bloodoak, and it takes 28 (8d6) bludgeoning damage at the start of their turn.
If the bloodoak takes 30 damage or more on a single turn from a creature inside it, the bloodoak must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the bloodoak. If the bloodoak dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.
Description
"The bloodoak is no ordinary tree. It grows far from the well-trodden path. You don't chop down a bloodoak, you hunt it, with all the skill and cunning that you can muster. It can take years to tread a path to the glade of a bloodoak, and great courage to bring one down. Its wood--stripped and properly carpentered--is the finest in all the world for strength and buoyancy, but at a cost..." -Chopley Polestick
Bloodoaks are huge, flesh-eating trees, feared by all who know of their presence in the world. Bloodoaks are typically not tall, but can grow extremely wide. At the very top of the trunk is an enormous mouth, ringed with enormous, sharp teeth.
Bloodoak timber is highly prized due to its toughness and its ability to withstand extreme temperatures.
Tarry Vine. By itself, the bloodoak is incapable of ensnaring prey. The prey is actually caught by the tarry vine, a symbiotic growth on the bloodoak consisting of long, mobile tendrils. The tendrils of the tarry vine wrap around the prey, reeling it in like a fishing line, dangling it above the bloodoak's mouth, and dropping it in. If a tendril is severed, three new ones sprout in its place, though this can be prevented by cauterizing the tendril stump with a flame. Once the bloodoak swallows its prey, the creature is crushed inside the trunk. The bloodoak devours the creature's flesh, and the tarry vine drinks its blood. Even forest creatures are afraid of tarry vines and instinctively avoid areas where one is know to grow, resulting in large, empty clearings in the near vicinity of bloodoaks.
Bloodoak Hunting. The wood of bloodoaks cam command a high price because, quite apart from its usefulness, it is also extremely rare, as bloodoaks are highly difficult and dangerous to chop down. Those hunting bloodoaks, known as a "felling party", first have to look for a ring of glades--this indicated that a tarry vine hunted around that area. Once the glades are located, the first sign to search for is the "deathstillness" (the eerie silence caused by a lack of creatures in the area). As the felling party approaches the bloodoak, they then have to look for the "underscent" (the rotting stench of death hanging around the tree). Once near the bloodoak, some of the felling party distracts the tarry vine while the rest chop down the tree.
