Well, thanks for everyone's advice. I did, in fact, lose the match. He did a number of things that were kind of iffy and we had to "clarify" a number of rules but it was still a fun game. I was going to do a battle report but I forgot to bring my camera so I'll just do something of a summary.
I fielded the 1000 pt list I had up on the other thread which basically consisted of 16 hormogaunts, 16 termagants, 8 genestealers, tyrant w/lash whip/bonesword and VC, Dakkafex, Sniperfex, 3 warriors w/twin-linked devourers, 3 ripper swarms.
He had 3 squads of wyches (2 squads of 10 and 1 squad of nine so the archite could join,) mounted in raiders w/ dark lances, an archite with one of those squads, and 10 warriors w/ dark lance and portal. The Archite and Succubi had combat drugs, tormentor helms, punishers, and the archite had a shadowfield.
DE turn 1:
He dropped the portal with his warriors.
Tyranid turn 1:
I shot at his warriors and dropped a couple with the venom cannon on the tyrant.
DE turn 2:
Warriors fire dark lance and wound dakkafex.
A wych squad that got +attacks from drugs came in from reserves and hit my front line of hormagaunts killing most of them and consolidating into my genestealers.
Tyranid turn 2:
Hive tyrant shot down the raider while sniperfex killed a handful of warriors in cover. They hold.
Dark Eldar Turn 3:
The other two wych squads enter play. They had rolled 12" assault for their drugs. Raiders fire on carnifex and hive tyrant to no effect.
(Note: I just wanted to mention here that at this point I had to clarify that he did not in fact have strength 6 power weapons on all his succubi and that his wyches did not have a weapon skill 6 making me hit back on 5's. Also, his rolls for combat drugs were behind terrain when I wasn't paying attention ie he told me later when the squads came onto the board what their combat drug rolls were.)
The squad with the archite assaults the hive tyrant (courtesy of 12" assault) and rolls a 10 and passes ld check so isn't affected by The Horror.
(I was really hoping he'd fail so I could shoot him with 16 termagants and the HT... ::sigh:
Tyrants dies. I didn't get to see all those dice rolls but when I ended up looking he had four 5's and/or 6's on the table. I thought that was his roll to hit but he said he already did that and these were his to wound rolls.
He also used his combat drugs like mad rolling for like 4 or 5 abilities. He said he didn't roll any double or triple ones so his guy didn't take any wounds from his combat drugs. I challenged him on this because I thought the drugs worked different. He assured me that GW put out an errata on this online. I asked if I could access this online but he said they took it off the internet and only his friend who wasn't there had a printed copy.
With the tyrant dead he consolidates into termagants in cover. The other wyches helped in the assault on my hormagaunts, rippers, genestealers, and warriors.
(I didn't know he could engage new squads without killing off the squad he was still fighting. His wyches not in base contact with genestealers moved 6 inches through terrain to "consolidate" into my warriors.)
More things die. I lose a number of bugs mostly to the power weapons and drop a few of his wyches in return. The rippers did great at this point.
Tyranid turn 3:
I shoot one of the two remaining raiders with the sniperfex. It drops. Dakkafex was just out of range to shoot the other one.
He finishes off the hormagaunts, rippers, and stealers in hth and focuses on the warriors. The termagants lose assault, and fail leadership because the tyrant died and they were thus out of synapse. (I was out of warrior synapse by 2 inches because of one of the models he killed.) They are run down and he consolidates 3" out of difficult terrain.
DE turn 4:
He shoots more dark lances at the sniperfex with no effect. His wychee with archite charge the dakkafex. I watch his rolls. My dakkafex survives. I strike back with two attacks and a mace tail. His archite is hit once, wounded once, and fails his shadowfield save! Yay! highlight of my game. Finally vengeance arrives. We assumed the archite lunged to attack and was summarily swallowed by the hungry fex.
The warriors are finally finished off in hth. (When he consolidated into the a while back he said I didn't get the benefits of being in cover with my warriors and thus didn't get to strike first because he consolidated into them. Is that true?)
Tyranid turn 5:
Sniperfex destroys the last raider with barbed strangler. (He didn't know blast templates got an extra hit on open topped vehicles.)
Dakkafex dies to lots of 5's and 6's from succubus with punisher. They consolidate into sniperfex.
DE turn 6:
Sniperfex invincible! One kill in return. Wyches pass morale.
Tyranid turn 6:
Sniperfex dies to lots of 5's and 6's. (Again I thought it was the first roll but he assured me that that was his roll to wound and not hit. All his attacks hit, I must have missed that roll.)
Final tally, I have no bugs left. He has two wych squads slightly over 50%, one wych squad below 50%, the warriors below 50% and no raiders left. I think this game could have gone a LOT better. Still, I had a lot of fun and will play him again soon. Thoughts?
