Would it be possible to make the blood of some creatures poisonous (or maybe acidic/scalding) so that dwarves who get it splattered on them in melee would contract some deadly disease?
Yes, very easily. You just make a material in the usual manner, give it a SYN_CONTACT syndrome, then replace the second BLOOD token in [BLOOD:LOCAL_CREATURE_MAT:BLOOD:LIQUID] with the name of the material you want them to bleed. I use something like this for a plague monk creature and one or two of them can incapacitate entire swarms of enemies just by bleeding on them.
P.S. You mentioned something about warpstone earlier, can you send me a link to the mod for that?
It's not on the Internet yet, because I haven't finished it.
OK, can't wait for that- how much other skaven stuff you got besides the warpstone and plague monks?
Also, two more things on contagions:
1. Could you put a (mild) contagion in cheap food/alcohol to give food poisoning and hangovers?
2. Could you make a contagion give a
positive effect? I'd like to make a workshop that just produces a vapor that makes my dwarves happier/healther. (Or, could you just find a way for a workshop to create steam? Although, I suppose that just putting a grate over lava and designating it as a pit/pond would be good enough: dwarves dumping buckets of water on lava = dwarven sauna. If so, it might be a good idea to make a material called, say, thermium and give it [MAT_FIXED_TEMP:9000] so that the dwarfs don't dy in the heat. Heck, you could maybe even make armor out of the stuff, to act as thermal insulation-
Arkenstone, Moddwarf has been possessed!)
