Just a few nooby questions

I just add my own contribution :

Have yer mage learn Winter Gasp as soon as possible (including it's upgrade). In many occassions, this skills + couple of warriors in front had held the battle quite nicely.

Winter Gasp will freeze the enemy on the spot, allowing warriors to attack him. If ya have two mages with this skill behind ya, and two warriors in front, have the leader issue a Hold Position and choke the point where the enemy comes through. Once that is done, just get the mages to use Winter Gasp and chop the enemy's HP down.

Only problem here could be of archers and enemy mages, so always keep an eye on the characters' HP.
