i havnt done any real experiments, but i assume they are repond.
as the normal EML's are repond (thats Evil Mage Lords)
on my disco tamer i find that even though i dont have med or focus, that dropping the disco mastery on the unbound EVs helps a LOT with getting them down faster.
so disco, dragon on, dispair whenever i can get the mana for it.
as for my pure bard i have been running the provo mastery with him.
gives all my summons more UMMMF
so disco, provo, drop some EVs and put on mastery or both.
some direct spells.
i also have been using my Vollems down there and they have been eating stuff up good.
course im being a winp and letting either a warrior or dragon take the hits and i put my vollems in after.
hope that helps.
