Welcome to Librarium Online!
This is my first attempt at a 1550 point mech list. I have about 800 points, so far, and i just wondered what you guys thought. I have included some of my thought on my choices as well.
Order of the Sacred blade:
Cannonness commander Josepha w/ Blessed weapon, jump pack, brazier of holy fire and frags
My leader of the army. She will go aroubnd with the seraphim. She has the brazier for a possible 3 template attacks when combined with the seraphim.
30-Inquisitor (yet to be named) w/ Bolter stake crossbow.
80- 2 death cult assassins
168-5 celestians w/ multimelta and Immolator (multimelta and smoke)
The inquisitorial help. The celestains are my tank hunting squad and have done quite well in smaller points games.
209- 10 sisters w/ Vet (book), heavy flamer, meltagun and Standard rhino*
202- 10 sisters w/ vet (book), stormbloter, meltagun and Standard rhino*
148- 7 stormtroopers w/ 2 plasmaguns and Standard rhino*
The bulk of my army. The stormtroopers will acompany my inq and lend high S firepower to the army. If it is necessary, they will be my sacrifical unit.
225- 8 seraphim w/ vet (evis) and 2 flamer pistols
My hammer unit. The vet is tooled up for comabt and is also capable of taking down tanks and big things if vital.
125-6 retributors w/ vet and 3 heavy bolters
70 immolator w/ heavy bolters
These choices will lend fire support to my army, with the immy and rets detailed to kill infantry.
Points- 1498, faith-7, Models - 50 and 6 vehicles.
* a Standard rhino has smoke and extra armour.
I'm not sure why you have the Inquisitor. A couple of DCA's hardly justifies it. If I take an Inq I tend to either have a 'naked' Inq with just the Liber Heresius, there in an advisory capacity, or a fully-tooled out one (usually cc, Retribs do the shooting thing better).
The multimelta Celestians are not too efficient. The AT ability of MM's is actually quite poor. They're short-ranged, inferior in firepower to a lascannon (no one, and I mean no one, moves a tank within 12" of a MM) and expensive. The MM Immo isn't too good either. Short range and thin armor mean that it's a poor tank hunter compared to an Exorcist. I'd give the Celestians two meltaguns and keep the Immo just a regular flamer one. That will give you a fairly inexpensive AT squad with a useful cheap AP tank.
The second battle squad could do with a heavy flamer rather than that stormbolter. Sisters in Rhino's do the rush and bail with DG tactic. In such circumstances stormbolter's are useless. I find that they are only ever of use when you stick five of them in a Dominion squad for use as mobile mid-range firepower.
The rest of the army is fine generally. With the Immo w/ HBolters I find that giving it blessed ammo is useful against certain opponents, principally Guard, Tau and Tyranids who have plenty of troops without 3+ saves and who often use cover. The canoness could maybe do with the Cloak of St. Aspira to protect her. A Book of St. Lucius on her would also be useful for keeping her and the Seraphim in the fight.
dpo you think i should get rid of that squad? Im not having more than 1 exorcist, as i only have the one mmodel and it is pretty unique, so what else can i use for long range anti tank? Also, i would love to add more assassins in, but i dont think i would be able to.
A MM isn't really long-range AT. In practice a meltagun has the same range, 6" move + 6" melta range against 12" melta range. Over half range melta weapons lose their enhanced firepower, making MM a short-ranged lascannon with slightly inferior firepower (S8 AP1 is equivalent to about S8.5). The mobile flexibility of meltaguns and their much lower cost makes them superior in practice. The celestian squad I detailed will give you mobile AT firepower at least equal to the old squad at a rather lower cost. An Exorcist, four meltaguns and an Evisc wielding Sera VSS should be enough AT firepower for your army.
Use some of the freed up points to give that Inq the Liber Heresius. A bolter-stake crossbow is nice but hardly necessary, it's a negligible amount of firepower. With the LH though the Inq justifies their existence and becomes a useful addition. Another good bit of kit for the Inq if you happen to be facing an army with any psykers in it (Eldar or Tyranids are best) are the Excruciators. For hardly any cost it can give you a nice bonus of victory points. Sit such an Inq at the back out of LOS, their job is not to fight and they should simply avoid giving away VPs.
More assassins isn't necessary, nor is it wise. Assassins are expensive, fragile and few in number. Take too many of them and these qualities will affect your whole army.
