Right going to be getting this chap for the primary reason that he looks a lot of fun to paint, but now trying to figure out how best to use him in a game.

he is entombed so can appear pretty much wherever he likes.
he can fly (can't march though)
he has regen and if he dies explodes and hurts things near him.
he gets re-rolls to hit/wound against any 1 enemy wizard selected after he is deployed.
causes Terror.

Now the obvious use is to pick a wizard and then go after him! but since he can't charge after turning up, this could prove tricky even with a 10" move and he has no chance of survival against a unit so that is a lot of points to try and kill a pesky wizard.

thinking he might be better at killing artillery crews? or small skirmish units - is this a good use or is he being wasted then?

bit of an enigma to say the least, if he deployed like any other assassin this would not be a problem but since he cannot even join a unit this is going to make using him tricky me thinks.

So what do people think? anyone even used him?
