Indeed, we seem to be stuck in a rut... I only found a couple of posts about tactics for playing as Dungeon. It's obvious that we need to raid outposts, crypts, and bunkers, but I'm interested in what tasks should be prioritized in the first or second week (while building up your castle, for example)...
My standard build order for Shaktii:
1 - Upgrade Trolls
2 - Build/upgrade Harpies
3 - Upgrade Harpies/1000 gold/Eyes
4 - Eyes/Medusas/sometimes GM1
5 - Build a suitable outpost
6 - Portal
7 - Citadel/Cats (if the situation allows)/MUSHROOMS!! (most often)
I don't see the point in developing Dungeon like other castles; we already have a strong main stack – the main task is to strengthen it.
