While usually an important implement at harvest-time scythes have been converted to weapons of war throughout history. A devious artificer has pushed this to the next level, investing a scythe with malignant life and turning them into terrifying skirmishers. The haft of a rusted scyther is pock-marked with rot, it’s rune-etched blade corroded. The animated weapon drifts silently through the air, striking when least expected, and leaving hacked and bleeding bodies in its wake.

Black Thumb. Instead of harvesting crops, a rusted scyther goes out of its way to destroy them. Imprinted with a hatred for all things green the animated weapon sets out to destroy the enemy’s food supply. The starving masses are much easier to fight and subjugate. To this end, the floating scythes will use their blight ability on crops and forest regions. There is a 50% chance that a scyther has already used some or all of its innate spells for the day on this purpose.

Toxic Rust. The former half of the weapon’s name stems from the red contamination seeping from its blade. First stolen from the blades of fallen devils the rust is then cultivated on torture tools before being transferred to the scyther’s head. Even a scratch from the weapon causes a victim’s body to weep blood and for gangrene to rapidly set in. Many have survived the onslaught of a rusted scyther only to pass in agony to its contagion .
