Order of spell casting for multiple mages
 

If you go into battle with, say, three mages, is there any way to control which mages cast first, second, and third? Like say you wanted to cast one of the effect the whole battlefield nastiness spells, but first you wanted to cast a spell to make your own troops immune. Is there any way to ensure that mage #1 casts the immunity spell and then mage #2 casts the nastiness spell, all in the first round?

Also, when using the communion spells, does the master have to cast his eplls before the slaves, or does it make no difference?

<font size="2" face="sans-serif, arial, verdana">Mages will cast their spells in the order they appear on the strategic map. If Grodvitner is listed before Alf on the map, Grodvitner always casts first in combat before Alf. Obviously, you can only discern this order if both mages begin in the same province, so you can see them listed in order. It's anyone's guess who will go first otherwise.

As long as the masters have become masters, and the slaves become slaves before any other spells are cast, the communion boost will apply. If spells are cast before the communion is up, then they will not be affected by the people who have yet to cast their communion master/slaves.
