Oh it's a useful spell, and I like using it. Just figured at 22MR (I know, coulda/shoulda been higher), that not enough of something like that should stick.
Worst part is, Chayots aren't that high HP, if I hadn't had the Ophanim clustered with them, your mages could have found something else to mess with.
Not that I think it would have made so much difference with your 55 commanders throwing all hell at me.
Which BTW, good move getting rid of all the human sized troops with the RoS/Earthquake combos - if you play them, remember they get no access to Arrow Fend.
