No, necromancy doesn't work on map 200. I barely managed to place ifrits in the fortress; the necropolis is blocked by 10+ monks. On day 12, I attack them without looking – there are 20 of them, 1 ifrit, 20 imps, 15 gogs. Then I attack 40 vampires for the relic, another ifrit, and a devourer. There are 50+ hydras there, and I have nothing to fight them with. I go to the second resource point, taking the rough terrain. I get attacked (2 ifrits, 11 gogs, 6 demons) and still have to deal with 1 more guard of the hive, 100+ gargoyles. I almost didn't finish them off. Hoping that the opponent won't arrive before day 131, I don't give up, but I miscalculated.
Thank you for your time.
Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
Rejoiceth not in iniquity, but rejoiceth in the truth;
Beareth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth...
