1. With the new geographical effects necromancers have in the upcoming update if a player necromancer makes a camp and collects enough undead minions can they cause a region to turn into it's evil version?
2. Since the new intelligent undead are technically sentient if a player adventurer gets killed and then raised back to life as an intelligent undead will we be able to play as them again if we select play as a specific creature reentering adventure mode?
3. Will player necromancers be able to create intelligent undead and if so how much of a corpse is required for it? For example could we make an intelligent zombie severed head?
4. Who controls intelligent undead if their necromancer master is slain? Do they become free willed undead?
1. Players don't currently have proper ownership of towers to facilitate that, as the new data bits being added to necro towers seem to indicate that they are the source, so this will probably always be the result of a NPC rather than a player necromancer.
2. Similar to other resurrection questions, i wouldn't think a creature that can't act on its full free will (to bend to you the player's imposed will) would be playable by itself even if its selectable, in all likelyhood it'll be greyed out from selection.
I wouldn't know where to start to answer the remaining two questions, they're that specific only Toady could reply, as id only be able to hazard a guess that intelligent undead have enough components to dissappear amongst refugees to live a quiet life milking cows at the disdain of villagers like the recent undead gorlak in the devlog who became captured and integrated. And that just a rolling head is not probably the kind of thing a necromancer wants to lead their armies so they pick out one that's not too rotten and disfigured.
