It's finally in hand, the Gloomspire Gitz book! I am so far out of step with AoS it's almost like starting with a new game.
I am reading through the warscrolls and there are so many buffs, spells, interactions, etc I can't possibly understand it all. It will take a lot of careful study.
And finally I dug out the Orcs & Goblins i have and pulled out the models that are in the tome.
So I have:
Leaders:
Fungoid Cave Shaman
Webspinner Shaman
Battleline:
50 (42) stabbas
35 shootas
20 Spider Riders (if webspinner is General)
Behemoth
2 Mangler
Arachnarock Spider w/warparty
No role
3 Loonsmasha Fanatics (5 is minimum)
1 Rockgut Troggoth (3 is minimum)
But that still comes to 2020 points! Dropping down to 40 stabbas puts me at 1920. Room for another unit easily.
Plus of course will need a loonshrine, as it's zero points!
I think I just need to to put this stuff on the field and roll some dice, see what happens.
