Warriors of the Five Elements.

In a MP game playing EA Tien Chi I centered most of my strategy around those guys.

Early game just recruit as many as you can, they take indies very easily.

Mid game, research battlefield damaging spells which your Wot5E are immune to such as foul vapours, wrathful skies etc and serpents blessing, storm warriors to make them 100% resistant. Few enemy armies can fight the Wot5E's while being posioned/lightning bolted etc...

When you add in all the other magic Tien Chi can throw around it can be a very fierce mid/late game nation but it needs a good start/luck early on.

Sadly, the host disappeared in that particular game so I never got to see how my strategy would have turned out, but I was in a good postion at the time.
