Archibald_TK from Warseer has the following information to add:
- The character with the two axes is the leader, his axes give him +2S and poisoned attacks. If I remember correctly they all have S6 T5 as base stats, plus a load of W and A. See how ugly his face is?
- The wizard has a cloud of flies that attack units like a shooting attack and count as magical. Also he carries an item that give him +1 to something and -1 to the same thing to all enemy wizards within 12" so I suppose it's to casting checks or whatever wizards do in WFB. He's the one with the stone thrower attack. I'm also pretty sure he's the only one without a 6+ ward save.
- Morbidex Twiceborn is the one I was talking with the regen aura for Nurglings.
