Rotspear is an item in Tyranny.
When crushed between the teeth rotspear seeds increase a soldier's might at the cost of inspiring frenzied rage. These seeds are gathered from jungles in the east of Kyros' Empire and carried by the Overlord's armies throughout the Empire. Though incredibly useful in battle, continued use of these seeds results in impotence. This worrying side effect is the source of the plant's name.
