Ore-Eater Kryptonite

[Paladance]

A Stitched Pup has Howl + Diseased Bite too but can also Consume Corpse.

A Lofty Libram is slower than both but has Amplify Magic (yes, that ability that nobody uses) + Curse of Doom and Shadow Shock.

Some Val'kyr swapping time with mitigated Haunt damage? :/

Sister of Temptation has Shock, Curse and stun and can be faster than that slower Eater.

For the faster Eater it has to be a flyer. Perhaps some sort of a nether ray/sporebat?
Or a Brilliant Bloodfeather with Peck, Hawk Eye and Drain Blood.
