Xeona on impossible - no casualties/5 units

[loreangelicus]

Xeona on impossible, no casualties and used 5 units instead of the 1 unit/rage drain/chargers tactic.

This battle lasted longer than the Karador and Ultrax dragons battles because Xeona kept on casting Demon Portal and got lucky with archdemon and demonesses, the two Demon types that can cause the most problems in a no-casualty battle.
