That and the undead are cool.

And not too bad as thugs.

Allows you to use all that cold, poison and death magic based battlefield spells freely.

Re: "Painless" Doc Jhonson, or how to kill your commander
 

just don't try wish. that leaves huge marks. yeah, a clean resurrection has long been a dilemma for me, too.

Try lycanthopos amulet : the commander will go berserk and be killed by the first indy province you send him to, and thanks to regen he will be much less likely to get an affliction.

And best of all, the twiceborn will make sure that the "curse" of the amulet is removed (all items are lost with the death of the commander, and even if you were unlucky to transform into a werewolf, the previously casted twiceborn should remedy to that)

Of course this will add some natures gem to the transformation ...

Are you sure you drowned him inside your dominion?

Re: "Painless" Doc Jhonson, or how to kill your commander
 

You can always send the commander to a province with a site that causes disease.... the problem is only that the wight will have only a single hit point and you will probably accumulate some afflictions before the commander dies....

Re: "Painless" Doc Jhonson, or how to kill your commander
 

see, that's not what the OP wants. Wights born of disease come back as crippled halfwits incapable of casting the simplest spell, or even lead more than ten undead.

The OP wants a clean kill. So do I, actually. I was quite disappointed when Wish did not grant me that. The OP wants his commander to die without injuries.

Theory to the rescue!
 

This is just theory mind you, I have never gone for a wish strategy and I hardly use undead so I might be overlooking something, but...

If casting wish is on the table, why don't you just use a wish to cure the wight of all afflictions?

Alternatively, summon a unit with heal (if you can) to get rid of the wights wounds.

I think all of the cleanest kills are already suggested.

Re: "Painless" Doc Jhonson, or how to kill your commander
 

Because 1) Wish doesn't do that.
2) Healing (except for GoH and the Chalice) doesn't work on undead.
