Wizard – “Hope of Zephyr” [Campaign 6, Mission 5]

Yes, Godric is quite powerful. Of course, replaying the game with him starting from the first campaign might not be appealing, but at least in the sixth game, you can "recruit" him, as he appears there. And in general, if you're playing version 1.0 (I don't know if it works in later versions), there's a cheat available during the battle with the Warlord: the "banish" spell. If Godric is lucky enough to acquire the "summon" and "banish" spells in an earlier mission, there won't be any problems with the number of troops; you can attack even with just one peasant ;)
