If I were Man i would do a test and see if seeking arrow hits stealthed commanders.
If so-problem solved(unless they all have amulets missile protection-unlikely). Though depending on the hps of the raiding commanders, it may take more than 1 seeking arrow to dispatch.
And if it takes more than 1, may not be worth the cost to kill one. Mind hunt oth, at 2 s gems a cast, is quite a bargain!
