Instability II

Instability II is an exclusive ability to the Clan Moulder faction introduced in Total War: Warhammer II The Twisted and the Twilight DLC.

It causes constant damage to the unit until it reaches 50% of its hit points.

Units may receive this ability when augmented in the Flesh Laboratory and it is the second of four negative passive instability abilities resulting from unstable augmentation.
