How to use mage in a battle

Almost any nation has rather fragile mages , especially for pythium this is true .


If you play e.g. Vanheim/LoT do the mirror images help against earth quakes , wrathful skies lightnings etc. or not ?

These spells make most national mages in quantities >5 rather useless .

Not totally useless, just useless in offsensive. Defending their own castle under the dome, they can be quite efficient. You only need to plan on opponent casting mass destruction spells and script your mages to cast all vital protection spells in the first round. Alternative/additional plan is to send some force to distract the enemy in the magic or break siege phase. If they're numerous enough, the enemies will likely spend their gems limiting their ability to cast mass destruction spells in the fort battle.

In other cases you may use more than 5 mages too, but you should be prepared to lose them, so it's rather a complementary force to your army.

Vanheim , Pan , Jotunheim + LoT are at least partially exeptions but all other nations should have extreme troubles there with their national mages .

This shifts then in lategame the balance more to SCs + Strong summonable mages ?

I think that shifts the balance more toward balanced armies: few SCs, few strong summonable mages, few regular mages, some strong summons and regular troops and some fodder summons/troops.
