Version 1.0 of factions’ plans is finished. I’ll test some delves more though: Sea of Sorrow, Frostfire Keep, Emperinazar. And if some things will be changed by the devs (The Labyrinth, for example), I’ll update data. (Update 1: I finally found 1 occasional treasure room in Sea of Sorrow.)
What can I say about factions so far? We can consider first factions (All-Seeing Eye, Hall of Guardians, Crypt Keepers, Sea of Sorrow, Primal Rift, The Warrens) as probe ones. Some of them have level I rooms. Later the devs withheld these unpopular rooms, and the lowest room level is II for all factions after Primal Rift, which was nice. More treasure and occasional treasure rooms were added for some factions, and it was nice too. All factions have 9 rooms (except the very first, All-Seeing Eye), and I believe 9 will be constant for all following factions: we unlikely will see a faction with 10 rooms.
The last faction at the moment, Duergaroth, brought new behavior in the game (well, almost new - the first was NUTCRKR 1225 from Adana): dealing with stone blocks. Creating, destroying and exploding them - that was very different than just removing them with other gems by some random mechanism. Before stone blocks were Doomskulls, and we have 3 delve troops to deal with them (Chaos Hound, The Maraji Queen and The Infernal Machine).
What will be the next addition to the board? And how factions will deal with it? Will there be more interesting factions’ plans (like Sunken Fleet or Lyrasza’s Lair)? Will there be more weapon concerning factions (like Chalice of Eyes)? How factions will develop after the last one will be added to the Underworld?..
