Looks interesting.
I'm going to be trying to build a non mech GK list, but the Dreads are very tempting with that setup!

What strikes me about this list (and a few others for that matter) is that at 2 thousand points the list only runs four tanks in the Land Raider and three Rhinos, aside from the Dreads, and while it certainly qualifies as a mech list for GK I can't help but think that GK aren't meant to just put everything in transports like other Marine armies. We just can't produce as many targets for the enemy's anti-tank and the points spent on it could be better spent on more bodies (and, ultimately, more Psycannons).

Just an observation I've been making about the recent deluge of Grey Knight lists. I wonder if the best lists use Coteaz for a combination of cheap scoring Henchment and Grey Knights as the heavier shock troops.

Why so many daemon hammers? I would change the purifiers to incinerators for your anti horde and min them at 5 or 6. You could also lower one of the Strikes down to half size and make another in a Rhino for these points giving you an additional squad in a Rhino. Might is a must! You may not need the daemon hammers as much with might as well. Quickening is good and all but just give him a halberd and he is at initiative 6 anyways. I like the list. Your list is definitely making me want to get out my crusaders again.

Spaguatyrine.

First off, I want to thank you guys for posting. Truly, I appreciate it.

Secondly, I should probably clarify is that I didn't mean this to be an oh em gee mech list that focuses on vehicles, I just wanted everything in a transport, for now at least. My title was a bit misleading. Sorry about that.

I agree that perhaps putting everything in a transport isn't necessary. I'm considering putting everyone on foot, maybe a Land Raider, or even taking a bunch of Razorbacks with combat-squadded psycannons outside of it. So many options, it makes me so happy!

It definitely seems the most competitive lists use Henchmen as dedicated transport-takers and some of the Grey Knight units to move out and actually take/contest objectives or table quarters. It won't be long until we see what the "best of the best" list is, and I'm sure many of us won't be happy with it, heh.

The reason I picked up so many Daemonhammers is to try to avoid getting stuck in close-combat with walkers and high toughness models. Plus, it helps for killing tanks in close-combat. Sure, I do have grenades and a lot of shooting, but I feel like they are worth it. Right now, at least. I agree on Quickening. 90% chance I'll be dropping it for Might at this point, perhaps dropping a master-crafted weapon or two for an additional power.

I can't wait to get some test games in, I'll let everyone know how they go.

I would mabe throw in a techmarine and put warp stabilizers on the vehicles but u might hav 2 sacrifice a few things

Does anyone know how to get a dreadknought with tw autocannons on both arms?

Sorry for taking so long to get back you you. Here is a great conversion guide:

It's a win in my book just because you're not spamming Coteaz-Henchman-Rhinos that seem to be in 95% of the lists I look at.
It looks like a solid starting point, of course everything changes after the first test game... but you gotta start somewhere.

hi im jarrod can i get some feed back on this 1500 list. HQ: Ordo hereticus inguisitor with condemner boltgun and psyocculum -65pts. TROOPS: 2 five man strike squads with a psycannon in each (objective holders) -110pts each squad. ELITES: 5 paladins psycannon, brotherhood banner, 3 haliberds and 1 master crafted daemon hammer -325pts. FAST ATTACK: 2 squads of 10 interceptors 9 haliberds and a daemon hammer in each -315pts each squad. HEAVY SUPPORT: nemesis dreadknight personal teleporter, greatsword and heavy incinerator -260pts.

Hey Jarrod,
While I love Interceptors and would love to run them similarly to you are in this list, I would really recommend either dropping them or downsizing them in order to pick up some more troops. You don't have much in the scoring department here, and if your enemy takes out your ten scoring models, you have no way to grab objectives. Remember, Grey Knights are not Fearless all around either, so you can end up running off the board, too. I wish I could give an alternative list to help out, but I'm really busy lately so I'll have to try to get back to you later.

Jarrod: just like Michael said,need more troops. Combat squad an interceptor squad there, and make another two strike squads out of the other interceptor squad; problem solved! btw your pally squad is brilliant, wound allocation shenanigans on two wound termies ftw!
