Health and drink

[Gilrandir]

I'm told (never tried it) that the easiest way for a king to be taken out is those little Greek-fire pot throwers.

You gotta have a knack of using 'em. Their range is short and accuracy is wayward and they cannot be employed in a wet weather. Plus only some eastern factions (the byz, the horde and the muslems (perhaps even not all of them)) train Naptha. But you may have luck and kill someone big as well as some of your own soldiers (the throwers themselves included).
