Bloodgorger Scythe

Usage held in 2 hands
Bulk 2
Category simple
Group polearm
Damage 1d10 slashing

This +1 striking scythe is made from the cruel, blackened branches of the carnivorous scythe tree, which hungrily drink up spilled blood.


Activate—Root in Blood (manipulate)
Requirements Your last action was a successful Strike with this weapon and your target isn't currently taking any persistent bleed damage
Effect You break off a piece of the bloodgorger scythe inside your enemy to feed on their blood and sprout into a new tree. The target takes 1 bleed damage at the end of their turn. Each failure to stop the bleeding increases this bleed damage by 1 as a small scythe tree grows from the wound, to a maximum of 3 persistent bleed damage.

Activate—Sapling Slash (concentrate)
Requirements A target has a piece of the bloodgorger scythe broken off inside them and has failed to recover from the persistent bleed damage for 3 consecutive turns
Effect The sprouted scythe tree grows large enough to be commanded. It makes a melee Strike against the target or a creature adjacent to the target, with a +18 to hit and dealing 1d10 slashing damage.

Craft Requirements The initial raw materials must include branches and roots from a scythe tree.
