[Maltrease]

My test didn't lead to any definite conclusion. It would be great if you could see the upgrade magic paths by looking at the unit.

I had 4 theurgs each cast slave followed by master and then scripted for 4 smites. It didn't work... although they were casting divine blessing and fanatism. There were valid smite targets within range.

I then tried 8 theurgs with the same script. In this case only 1 theurg cast smite... the others didn't do anyting. It was like they just skipped their turns.

I haven't tried scripting them for other spells yet. Maybe that would offer a clue?
