Welcome to Gaia! ::

Nids: Watch out for Warp Blasts. They will always need at worst a 4+ to wound everything that isn't a god in your army, plus they ignore most of your saves. Rending attacks are also bad, so watch out for genestealers. They will shred a squad if they reach it. Finally, remember that When within 12" of a Synapse, all Tyranids are Unbreakable, so don't have a Nightbringer move up in the first turns to charge a nid squad, or you'll end up having to fight the big bugs also.

Chaos(Undevided): This army type tends to do well with leadership and will usually be tooled for either ranged or Close Combat. As long as you avoid any possessed or Demon Princes they have(In close combat, shoot them down quickly!), you should do fine.

Slaneesh(The Pink Ones): These guys can be a problem. Their demons have rending, a huge problem for Necrons. Also, Their Powerfists strike Simo With most of your basic Warriors(All enemies in base contact with a Slaneesh models are at -1 Initiative.). They also have some well skilled shooting units. However, Slaneesh armies tend to lack anti-armor ranged weapons, so if you have a monolith or High Toughness HQ, it should be safe.

Will continue post asap.

Tzeentch(Oh look, another Psychic...): OK, these guys are pretty different from the other Chaos armies in a few ways. First off, a 15 Man Chaos Marine Squad with aspiring champion has 29 Wounds and a Psychic in it. This army also has a specal rule that makes them always count as moving through difficult Terrain, they never get the charge Bonus, but they always count as have being stationary. Luckily, these guys won't use much Heavy Weapons or transports. Howevevr, they have some pretty nasty items and Psychic powers. One Item allows characters to use Blast Templates with their Bolter Rounds, this can me deadly if you pack your troops too close together. They also have thralls, which means they can cast an additional spell for at most three turns. This can be a problem as some of their spells are the equivilant of a heavy bolter, while another is The equivilent of a mobile Krak missile. They also automaticallly pass all psychic tests, so don't plan on getting a lucky Perils of the Warp on them. But remember as I said, they are SLOW. Use this to your advantage, and don't forget that all Troop-Choice Chaos Marines they take(Except champions) have 2 wounds each. Finally, a big piece of advice. If you see any Character in the army who looks like they may be carrying a Bedlam staff, keep your nightbringer away from him. Especially if he has furious charge. This model would be able to not only strike before your nightbringer, but if he even caused one wound to get through, you wouldn't be able to attack either this round or the next round of Combat. This is deady because it means that he could kill the Nightbringer, though if you have a good unit charge with him to get enough attacks in even without the Nightbringer, you could probably take him down.

Tau(Ah! A knife! gonk ) Ok, these guys can be deadly in their shooting. Their Broadside Teams have weapondry that could easily take down a monolith, and their basic warriors can shoot S5 shots at 30". This means you should use whatever you can to keep your army intact. However, if you have any Close Combat Units, get them as close ASAP. Anything can tear apart the Tau in close combat. And if they have kroot? Blast 'em so your Combat troops will go unappossed. Just remember though, tau can still attack in close combat, and if they are near an ethreal, odds are they ain't going to run.

yea...but missions like cleanse they're usually too slow to take enough table quads...

I'm not a Necron player, but my primary opponent is, and I'll pass some tips on to you.

Against my Tau, the worst thing I can hope to see on the table are more than 5 Destroyers, with hordes of Warriors coming in a close second. My Tau have some pretty nice firepower, but they can't hit all that well, and if you take a ton of warriors and a large number of Destroyers, I'll have a very tough time killing enough in one turn in order to deny WBBs. Most of my weapons don't deny armor saves, so denying WBB is my biggest goal. I'll dance for joy if I see 3 Wraiths, 5 immortals, or any Paraiahs or heavy destroyers on the table, because those are just going to disintigrate under focused fire. Don't forget, there's no need to take Heavy D's at all, because just about every weapon in your army can glance any vehicle on a penetration roll of a 6, and you can't penetrate skimmers that have moved over 6" anyway.

I don't fear your Monolith, as my Railguns have about a 50/50 chance of turning it into so much slag. Your Nightbringer may be a crazy assault monster, but it only moves 6", and it's only ranged attack is a bolter range lascannon shot. Above All Others means I can blow him away by turn two if I so choose, or I can just ignore him, as he ends up being about as useful as an assault carnifex (i.e.; the chances of him reaching my lines are near to nil)

Also, the Nightbringer is 360 points. 360 points. That's as much as a 20 strong squad of Warriors that's more survivable, more useful, and adds to your Phase Out count. I don't think he's worth it at all, but if you do take him, don't do it in games of less than 2000 points. The Nightbringer might do pretty well against assaulty armies, since they'll attempt to assault him anyway, but against Tau he's just a very expensive fire magnet.

Summary: Against Tau (or in general, really) Take lots of Destroyers, take lots of Warriors, never take Pariahs or Heavy D's, and ditch the Nightbringer in smaller games.

Well, I'm back with another question. My friend and I are having a little debate regarding the Monolith and the glancing hit chart.

My view is that a Monolith shouldn't suffer any result from a crew shaken/stunned roll on a glancing hit since the Monolith has NO crew. My friend thinks that it should still suffer from the results since it doesn't say anywhere that it doesn't.

So, what do you all think? I guess I could accept being wrong, but it still wouldn't make much sense to me...

While you may choose to house rule that it can ignore shaken and stunned results, official rules say that it can be. Remember, 40k runs on rules, not on logic. To paraphrase a guy at my local gaming store "Unless the rules specifically say that you can do(or ignore) something, assume you can't(or have to) do it."

How many people think the Necrons are going to play a large role in the next summer campaign? Will you collect an army just for the occasion (if you don't already have one)?
