Here are the units involved:
Lone Wolf w/Thunderhammer and Stormshield
5 Thunderwolf Cavalry w/1 Thunderhammer
Knight of the Flame w/MC Demonhammer
Xenos Inquisitor w/Rad Grenades
The Space Wolves charged my Purifiers. The Lone Wolf and a Halberd get locked up together and everyone else on the Thunderwolves. To start off the combat I can’t cast any psychic powers because I need to save it for the Force Weapons. The Rad grenades lower his Toughness to 4 (this was a big argument because he did not think that one IC’s grenades can work on his whole squad but in the rules it clearly states that it affects the unit). On to the combat; both of my Halberds whiff to start the combat at I6. Then the scrum begins. He does all of his attacks and I can’t make a save and he kills all 6 of my Purifiers. I strike back and do 4 wounds. Because he has 4 un-upgraded Thunderwolves he places the wounds on them and removes 2 models so I can’t force weapon them. This does not sound right and I start looking through the rules for wound allocation. After spending a reasonable amount of time I let it go. (This is my MO for tournament play. If I can’t find the rule in short amount of time I move on). Then my Demonhammer swings I do two more wounds and he takes another model off. In the next round he kills my Inq and my Knight of the Flame and those 2 Thunderwolves then go and kill all of my vehicles giving him the win after tabling me. That loss cost me the win and a swing of about $40 in store credit.
I know that the way he allocated the wounds in this manner was incorrect because then force weapons would be useless because you can never kill units of multi-wounded creatures. It was not until that night that I found the correct rule about units with multi-wounds against weapons that cause instant death. The rule is that if you have a weapons that inflicts instant death you have to apply each wound to each unwounded model and that model is removed.
So if the rules would have been played correctly then I would have killed those 5 Thunder Wolves and then had a good shot at killing the Lone Wolf. Oh well, each game you learn something new and will play the rule correctly in the future.
Oh well, I need to brush up on my rules. This is the same store where I played a Tau player and after shooting shield drones he told me that they were wargear and that they did not count for leadership checks, and I know that they did. I did not know where to find that rule and it was right in the Tau codex under drones.
