Here's a post I made that discusses the app modifiers:
You can change the appearance modifiers (and thereby the ingame size) of any body part, but that's it short of a full transformation to a different creature type:
[CE_BP_APPEARANCE_MODIFIER:START:0:BP:BY_CATEGORY:TOOTH:APPEARANCE_MODIFIER:LENGTH:150]
[CE:COUNTER_TRIGGER:DRINKING_BLOOD:1:NONE:REQUIRED]
So you could make a creature's eyes become huge, bulging and red, or transform a creature into twice its normal size, but you couldn't make it sprout extra limbs.
Yeah, I meant to say that this sort of "body change" is something that can be done (though it's not a body change in the sense that the body definition changes).
yeah i kind of got the vibe that he planned some other form of improvement for them, not sure why.
Toady mentioned a generation counter for vampires for power dilution and similar things (which would be the inverse, weaker with youth, but pretty much the same end result), but he didn't get around to it for this release (much like the monstrous vampires will have to wait).
In any case, vampires are probably the closest-to-living undead in most myths and fiction (and in some rare fiction, technically are alive), and as such it seems that at least a few vampire types could improve in strength if they wanted. Similarly the necromancers, who seem to be mostly still alive, than some kind of undead lich (for liches again it would depend, but they are usually less close to the living).
Any plans for hereditary curses? "Your family shall suffer for seven generations" seems like a pretty common tropes, and it would be funny to see babies spontaneously combust because their parents had a nasty run-in with a mummy two years ago.
Also, and I know this isn't the question anyone wants to read, but is there are roadmap to the next release? Like, right after the mummies and tombs? Or is there another thing after the Mummies before release?
We don't have any specific plans, but it's a reasonable thing. I think we were thinking of doing some kind of generation counter for vampires so that you could do things like power dilution etc., and that might be related, but it wasn't done either, so it doesn't matter yet.
