1. What about necromancers will allow them to raise things? Will they make some sort of magic object which simply raises any dead in the area? Will they use some sort of nebulous power thats inherent to them? Will they be somehow able to raise themselves if they die, such as a Lich.
We already know all this from the devlog. They discover a secret, either directly from a death god, or indirectly through a slab engraved by a previous necromancer. If lichdom were going on, I imagine he'd have mentioned it.
2.Will the necromancers make only one kind of dead or will there be multiple types with different duties, something like a ant nest. Will there be ghouls which scavenge the dead, living meat wagons to carry them, hulking flesh golems for combat, living pipe organs broadcasting the arrival of undead armies, etc, or just a wave of zombified woodland creatures?
There's just the one type, a creature raised. I'd imagine they can be zombies or skeletons depending on how the corpse is. There are certainly none of the silly warcraft-type fleshcrafting stuff you're talking about. I'm rather glad that this is the case actually. Such things make the whole procession rather farcical.
4. Now that we have the general raise dead curse effect, will it be possible that this effect is placed on artifacts or items? Ie, that Shiny blue sword found down in the Curious structures near the bottom of the world might have the unfortunate effect of raising your enemies to try to kill you over and over.
From Toady's answers in the last thread:
Eventually, but not yet. I imagine anything that comes of artifacts etc. will use the interaction system.
Also, as an unrelated thing, I really want an option to "Raise former adventurer", like the reclaim fortress option but to bring a dead adventurer back as some sort of wraith. Because everyone knows that, with truly awesome heroes, death only makes them angry.
Personally I would rather, if we get such an option, to make violent egress from the underworld. But I'm not sure if this will ever be possible, and it doesn't seem compatible with DF's current idea of what happens when you die. Perhaps when gods get some more love, it'll become clear. It would make sense if gods make new bodies for their followers to wear in the afterlife (as YHWH is said to do in Revelations), and it would then be possible for a suitably awesome adventurer to leave said afterlife somehow. But it shouldn't be easy. You'd have to be massively armipotent and perhaps have some sort of magic as well (secret of rebirth?). Certainly a fun possibility, though not any time in the near future I'm sure.
You know what I am truly excited about? The fact that this release is probably going to be more the rule than the exception. I'm betting that every one of the next few "new content" release cycles is going to have a fun element in it that Toady is going to enjoy coding (and that we're going to enjoy him coding) to help get him through what is obviously a necessary-but-tedious set of releases.
We get crypts, and dungeons, and night creatures in this release. I am eagerly anticipating what we're going to be getting in the next few releases too.
Personally, I am in far greater anticipation of the actual caravan arc stuff, and the army arc stuff after it. This fancy undeath is all well and good, but I'd rather get economic and military stuff to play with sooner, and leave magic and slightly more compelling undeath until after the current dev page is taken care of. I do understand that this is the main portion of what Toady does with his time, and he does what he enjoys, and I don't begrudge him that. But I certainly don't want him to take time out for things like this for my sake, and I'd imagine I'm not alone in my preference there.
That said, there is some significant potential to do interesting stuff with city-dwelling vampires and similar, and I might very much enjoy what happens with them once cults and organizations get implemented and we can have a proper sub-society of shadow rulers. But I don't imagine they'll be much like that in the near future.
