Troops are the biggest problem with Caelum... being very resistant to cold and lightning, you are very well covered against magic.

You have the most mobile troops in the game - I use them to lure enemies into my mages, via clever use of Guard Commander script. This takes care of HI very handily.

You really do control the mobility on both the strategic and combat maps, so use it to your advantage. It never goes out of style. Take a look at some battlefield enchantments and evocations, use archers with wind guide against masses, outfit some Eagle Kings as high quality thugs and hit them in their rear PD with Cloud Trapeze once you have 4 or 5 done up in this way. In two turns, you can own ten of their provinces and suddenly they're not expanding any longer, possibly with their main armies cut off from the homeland, reinforcement, and beleaguered by their other opponents.

Don't try to stand up to their big armies, counter strength with weakness. In fact, your PD is absolutely atrocious and not worth more than enough to give a chance of defeating some rituals or random barbarians.
