Its not really core to their identity as a faction and would require a ton of code work for very little gain.
actually it is flavourful, as AH said the skaven pretty much mined most of the Cursed Pit (the Unique feature) out from under Nagash's nose before he realised. and it will be very simple to implement it as AH suggested. but your right that the AI will never understand it.
Flavorful things like this are much better handled with events than in-game worker missions or spells.
good point
heres an event chain for skaven that could be interesting:
Light Magic Experiments: Requres, be skaven, a source of mined warpstone in the players border, be later than turn x.
"Your Skyre Council has approached you and suggested they have discovered a way to manipulate warpstone to produce massive ammounts of energy as the Wind of Hysh. They say the Warpstone deposit near [city name] is the perfect site of such an experiment what shall we do?"
a) this sounds intreguing, allow them to conduct their experiments.
b) massive ammounts of energy you say? perhaps that will help us mine more warpstone! help fund the studies! (-x gold)
c) That sounds dangerous, tell them to go ahead but make sure they dont do anything that could damage our empire (-y gold)
d) Why would you want to tamper with our perfect warpstone!? dont let them near it! (no effect)
if chose option a) triggers "Light Explosion a" event
if chose option b) triggers "Light Explosion b" event
if Chose option c) triggers "Light Extractor" event
Light Explosion a Requires: chose option a) in "Light Magic Experiments" event.
Sire the experiments that the Skyre Council were conducting on our warpstone mine have backfired! An enormous explosion of blinding light has flooded our tunnels and all the mines have collapsed and new fissures have appeared! what should we do?
a) Damn those no-good Tinkerers! Have Clan Eshin assassinate them for their idiocy, well have to rebuild our mines. (remove Clan Skyre HQ, Lose all mines on the map including non skaven mines.)
b) Curses! sned out all workers and slaves to the collapsed mines, have them rebuild them. (Production in all cities is stopped for x turns, no mines are lost in your empire, all other mines are lost.)
c) New Fissures ay? send out excavation teams to search them. (-y gold, lose all mines on the map, spawn z random sources of Warpstone, copper, iron, gold and silver)
d) Fund an exploration and rebuilding effort. round up every slave and worker and whip them to rebuild the mines, search the new tunnels. (-y (times 3), no mines are lost in your empire, all other mines on the map are lost, spawn z random sources of Warpstone, copper, iron, gold and silver)
Light Explosion b Requires: chose option b) in "Light Magic Experiments" event.
Sire the experiments that the Skyre Council were conducting on our warpstone mine have backfired! An enormous explosion of blinding light has flooded our tunnels and all the mines have collapsed and new fissures have appeared! Clan Skyre say that though the experiment backfired they discovered a way to speed the extraction of Warpstone from the ground using Warp power... what should we do?
a) Damn those no-good Tinkerers! Have Clan Eshin assassinate them for their idiocy, well have to rebuild our mines. (remove Clan Skyre HQ, Lose all mines on the map including non skaven mines.)
b) Curses! send out all workers and slaves to the collapsed mines, have them rebuild them. (Production in all cities is stopped for x turns, no mines are lost in your empire, all other mines are lost.)
c) New Fissures ay? send out excavation teams to search them. (-y gold, lose all mines on the map, spawn z random sources of Warpstone, copper, iron, gold and silver)
d) Fund an exploration and rebuilding effort. round up every slave and worker and whip them to rebuild the mines, search the new tunnels. (-y (times 3), Production in all cities is stopped for x turns, no mines are lost in your empire, all other mines on the map are lost, spawn z random sources of Warpstone, copper, iron, gold and silver)
e) faster warpstone extraction you say? excelent. have all the workers and slaves rebuild the mines and have Clan Skyre install this new technology. (Production in all cities is stopped for x turns, no mines are lost in your empire, all other mines are lost, all Warpstone deposites in your empire provide +1 hammer)
Light Extractor Requires: chose option c) in "Light Magic Experiments" event.
Sire the experiments that the Skyre Council were conducting on our warpstone mine were a great success! They say they have created a new device called a "Hysh Extractor" they say it uses the power of Hysh to disintegrate rock and extract warpstone much faster than normal! what shall we do?
a) Excelent news! have Clan Skyre rewarded and have them install these contraptions in all our warpstone mines! (- x gold, +2 beakers from Skyre headquarters, all Warpstone Mines provide +1 hammer)
b) Excelent news! have Clan Skyre install these contraptions in all our warpstone mines! (- y gold, all Warpstone Mines provide +1 hammer)
c) Desintegrates the rock you say? That sounds dangerous, perhaps fund Clan Skyre to conduct further tests to make sure its safe. (- z gold)
d) Really? (no effect...yet)
if Chose option c) triggers "More experiments" event
if Chose option d) triggers "Upgrade the mine a" event
More Experiments Requires: chose option c) in "Light Extractor" event.
Sire the further studies by Skyre Council on our warpstone mine were a great success! They say they have refined the technology and installed safty mechanics which contain the magic while boosting production! what shall we do?
a) Wonderfull!! have Clan Skyre rewarded and have them install these contraptions in all our warpstone mines! (- x gold, +2 beakers from Skyre headquarters, all Warpstone Mines provide +2 hammers)
b) Excelent news! have Clan Skyre install these contraptions in all our warpstone mines! (- y gold, all Warpstone Mines provide +2 hammer)
c) Really? (no effect...yet)
Upgrade the Mine a Requires: chose option d) in "Light Extractor" event, have x gold, have a warpstone mine.
Sire remember the discoveries by Skyre Council on our warpstone mine? they have offered to install the technology in the warpstone mine near [city name].
a) Really? thats awfull nice of them, i wonder what they want... better give them some cash just in case (-x gold Warpstone Mine near [City Name] provide +1 hammers)
b) we dont need it yet. (no effect, choosing this option alows this event to trigger again later)
Upgrade the Mine b Requires: chose option d) in "Light Extractor" event, have x gold, have a warpstone mine.
Sire remember the discoveries by Skyre Council on the Hysh Extractors? they have offered to install the technology in the warpstone mine near [city name].
a) Really? thats awfull nice of them, i wonder what they want... better give them some cash just in case (-x gold Warpstone Mine near [City Name] provide +2 hammers)
