Just make it a Tiamat upgrade and balance the passive it around bonus health.

+ + 680 g = Atma's Impaler (3300 g)


 * 45 AD, 45 armor, Cleave passive, Crescent active


 * Unique Passive: Gain 2% of bonus health as Attack Damage.

This way the it em is not gold-efficient by itself, but requires health from other items to become efficient. Som ething similar to the current.
