So I received a Mega Loyal Batik Eggaloon that had Death Throes 2, but whenever it used Death Throes, the enemies would take no damage. When the Eggaloon was defeated in Bestia, Death Throes was resisted by all of the nearby enemy pets. When my pet was defeated in the Ophidian Palace, Death Throes was resisted by all of the nearby Ophidians. I'm not sure if Death Throes 2 just has really low damage, but it doesn't really seem to do anything.
