Masteria Expansions, Names and the proof for each

Well, yes, but fire and lightning surely can't put out fire, and poisoning a fireball is rather useless. That leaves you with Ice and Holy. Do Bishops need any more incentive to be in this battle than they already do?

Besides, things like Firebombs and Bains are Ice-weak, so why not?

If they make the Grandmasters Holy-weak, (because they're from Versal, some speculate) then Bishops can nuke them to death. Some boss for AMs. (Maybe Palis, but there are far more Bishops.)
