So I bought the tome (been waiting for this tome since the second GH dropped), herdstone and 3 start collecting boxes, going into the army completely fresh, Currently built all 3 shamans, 1 Cygor, all 3 Bestigor units and 1 unit on ungors, should I keep to the regular ungors or have a unit of raiders as a sacrifice? and I plan on having at least 1 cygor and ghorgon, but what should i have the 3rd one? also have a Beastlord on the way. Local GW store games are typically 1500 points so currently my list is: Gravespawn Heroes: Beastlord - 90 - General - Mutating gnarlblade Shaman -100 - spell: savage dominion Shaman - 100 - spell: Tendrils of atrophy Shaman -100 - spell: Titanic fury Battleline: 10 Bestigors - 120 10 Bestigors -120 10 Bestigors -120 10 Ungors - 60 10 Ungors - 60 10 Ungors - 60 Monsters: Cygor - 180 Cygor -180 or Ghorgon - 200 Battalion: Desolating Beastherd - 150 Total: 1440/ 1500 points 2 extra CPs I have 2 Chaos Spawn for the Gravespawn ability and will have either a Cygor or a Ghorgon ready for summoning, along with any units that go pop. I'm looking to add a dragon ogre shaggoth (grave spawn artifact and the CA with the Titanic fury spell and summon lightning spell on top just makes me happy) at some point and a fair few Gors in the future, anything else I could/ should add?
