Hi guys! Recently my gaming group decided to restart our Mordheim gaming, and as it was to be expected, right at the very beginning some rules questions occured. Maybe You guys can help us out?

1, The Eagle Eyes skill says that i have +6" to "all missile weapons" range. But there is actually some confusion about what is and what is not a missile weapon. The thing is, that in the trading section Price Chart all range weapons are in one common box titlet "Missile Weapons". But on the other hand, in the part of the Rulebook that describes various equipment, there are two separate chapters for range weapons: "Missile Weapons" (page 44 of the Rulebook), and "Blackpowder Weapons" (page 47 of the Rulebook). The question is than, do the blackpowder weapons count as "missile weapons" and have +6" bonus from the Eagle Eyes skill, or do they not?
2, The second question is about healing herbs. The description is not very cler about it. So:
-> Can I use them only 1 time and they vanish?
or -> Can I use them 1 time per battle, but in multiple battles?
or -> Can I use them as many times as I want but in one battle only?
or -> Can I use them as many times as I want, through multiple battles?
The item description would suggest the fourth possibility, but than the herbs seem to us a bit too powerfull.
Oh, and one more thing. Can undead (like the vampire) use healing herbs? It seems against the fluff, but rules don't specify it. How do you play it?
3, Third question is about armor. I suspect the gromril armor is a heavy armor type and ithilmar armor is a light armor? It doesn't state so anwhere, i just assume it because on the Price Chart gromril is next to heavy and ithilmar is next to light armor, but this is only a clue. So I would like to make sure if my skaven can wear Ithilmar armor or not?
4, (edit) Here goes another one: If a Mutant form Possessed warband has a tentacle mutation, can he still use 2 weapons for an extra attack, or a weapon and a shield/buckler, or a two-handed weapon? Fluffwise he probably shouldn't, but on the other hand, the mutation description does not specify it, as it does in case of the great claw mutation. So how do You play it?
Cheers!
