New to DE want a scalable themed list need help from an Archon?????

Never played Dark Eldar always been a space wolves player.

Now I have been drawn into the darkside, and really want to do a webway dark eldar list.

With a strong cthulhu theme to it using bits from the cronos engine for tentacles and an archon with a lohkir fellheart model.

I also would like to have no named characters, and I have an irrational draw to the scourges, grotesques, vipers, voidravens, and razerwings.

So with all of those ideas and fancies I have no idea where to go and how to be effective???

Any help would be greatlly appreciated.

I used to be a twolf lord player a full fledged four lords of the apocalypse style beatface list.

Now Iknow that won't work with DE anything super face and relativelly beatface would be awesome.

I like your username considering your theme

There's a good basic 'DE and you' info dump I did on Dakka, also includes other useful links.

Your list of models you love is mostly okay, but I just want to point out a few things;

Archon - assault HQ
Scourges - anti mech FA slot
Grots - anti...well, anything they get their hands on but anti-infantry really - Elite slot
Vipers (I'm huessing you mean Venom) - anti infantry transport
Voidravens - anti mech Heavy slot
Razorwing - anti-infantry Heavy slot

Okay, the conflicts in theme I see are this - first, grots can't use Venoms, so they'll need WWPs or Raiders (footslogging really isn't a sensible option)
Army lists filled with Razorwings *and* Venoms will have a lot of problems killing mech.

Personally I don't like Voidravens, but it looks like they're probably your optimal heavy slot. You'll also still want to add in more anti-mech shooting, so some Scourges will work okay for that.

The rest of your army can work pretty well with Archon/Haem in a Raider with Grots and assorted Troops in Venoms (generally with more anti-mech tools as the Venoms will cover your anti-infantry that the Archon and/or Grots don't.

Hope that helps.
