Expanding with Kailasa is a breeze. With just 5 sacreds you can take almost any province. If you take a nice bless, of course. I like the S9W8A6 one. The problem is finding someone to bless your yavanas as your only recruitable priest is 360 gold. So, you should start recruiting indy priests ASAP.

Rainbow seems completely unnecessary, as Kailasa has great magic diversity. You have all paths except blood available at least at level 3 (with the exception of nature which is available at level 2). So, take an imprisoned pretender and a good bless is my advice.

When fighting indy archers, you just take some archers decoys with you (which cost you 5 gold a piece). The small air shield and twist fate should prevent taking much loses. When fighting human opponents, consider taking bandars as archer decoys, in case your opponents scripts his archers with fire largest.

Kailasa recruitable sacreds are top notch for initial expansion and against any nation without good archers and death magic (skelly-spamming). But if you run into Caelum, Ctis or god forbid Sauromatia, you're going to have a very hard time.

I would also start with alteration, but not because of ironskin, but because of body ethereal. Since you will be leading your yavanas with a yogi (to lead them) and an indy priest (to bless them), you might as well use the yogi to cast some body ethereals. With 5 yavanas in the group set to hold and attack and with 3 castings he gets before they run forward, yogi will cover each of them and himself with body ethereal in each battle.

After that go to thau6 for celestial music. It gives you 2 attacks per round and together with water bless pushes yavanas defense over 20.

Of course, with their awe, good stats and earth magic for buffs, yakshas are great thugs. But, why wait for turn 6 or turn 3 to start expanding and not have a good bless, when you can do it from turn 2 while having a good bless. And that good bless comes in handy for all your summonable sacreds as well as any thug or SC who you give a shroud.
