Scripts to defeat earth attacks or ashen angels

[incognito]

Playing Kailasa in a MP game with some friends and getting hammered by earth attacks. I've found bodyguards are not doing the trick in most cases, since 1 death results in the troops and commander routing, and the loss of everyone.

For reference, I am looking for any combo of spells across any mage types that helps defeat these two attacks. My S1, and S2/N1 mages so far have no luck. My E3 Yaksha can drop an earth elemental with two close range castings of blade wind - this is the only successful cast combo that saves them, albeit it does not work on the ashen angels.

I also lose W4 Yakshini easily to assassination spells, since water seems to lack offensive punch in these mano-au-mano situations.

Ideally, I'm looking for solutions other than using heavy gems or equipping guys with great gear (although a single item that is reliable would be good).

Thanks in advance for ideas.
