Asanbosam

CREATURE 6

Asanbosams are monstrous, hairy humanoids with cold iron fangs and muscular limbs that end in powerful, hooked claws. They hang in treetops from their hooked feet, waiting patiently for a creature to pass by below. Asanbosams grab their prey from above, latching onto their unfortunate victims' necks to drain their blood. They react to perceived intrusions with belligerence, stalking visitors from high branches. Locals tell horror stories of these "bloodsucking tree-folk," and experienced explorers keep a close watch on the treetops in asanbosam territory. Visitors to the Expanse often compare asanbosams to vampires, but these horrors aren't undead and bear no relation.

An asanbosam's diet calls for a large amount of iron (typically in the form of blood) to maintain the integrity of its oversized cold iron teeth. When not hunting or mating, an asanbosam spends its waking hours chewing on certain types of rocks to sharpen its teeth.

Some folk tales claim that asanbosams are as old as time and the original source of cold iron, and that veins of the metal found in the ground are truly the graveyards of ancient asanbosams. Brave (or foolish) poachers often infiltrate asanbosam territory to hunt these monsters in the hope of collecting sacks of their valuable teeth.

Attack from Above

Requirements The asanbosam is positioned above a creature

Effect The asanbosam makes a claw Strike with its reach increased to 15 feet. On a hit, the Strike deals an additional 1d6 slashing damage and the asanbosam immediately Grabs the target and pulls it to a space adjacent to the asanbosam.

This counts as two attacks for the asanbosam's multiple attack penalty.

Drink Blood

Requirements A Grabbed, Paralyzed, Restrained, Unconscious, or willing creature is within reach of the asanbosam's jaws

Effect The asanbosam sinks its teeth into the creature to drink its blood. If the victim is grabbed, this is automatic; otherwise, the asanbosam must succeed at an Athletics check against the victim's Fortitude DC. The victim becomes Drained 1 and the asanbosam regains 10 healing HP, gaining any excess Hit Points beyond its maximum as temporary Hit Points. These temporary Hit Points remain for 1 minute.

Drinking Blood from a creature that's already drained increases the victim's drained value by 1 to a maximum of drained 3, but doesn't restore any HP to the asanbosam.

A victim's drained condition decreases by 1 each week. A blood transfusion, which requires a successful DC 20 Medicine check and a blood donor or sufficient blood, reduces the drained value by 1 after 10 minutes.

Grab

Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained

Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.

The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
