Will do, first fortress fell.
Dwarves attacked, got crushed by my 3 women strong defense force. All of them in full stygian bronze gear, 2 whippers, 1 stygian bronze styx pitchfork with blight shards... All fully enhanced with firespells, immunity and that kiss move. 12 full iron dwarves got crushed, assembled them in the 3x3 wide entrance hall, dwarves got in and got serrated by the fire of my succubi. Didnt expect that much and kinda wish my full adamantine military on my current main dwarf fortress would kick that much ass... they are just tanks... while succubi hit damn hard. Ok good, now I decided to put a drawbridge just in case... elve ambush detected, crap full mithril. Well, lets raise the drawbridge... oh 2 hunters outside, shit... Lets lower it... whoops now those poor succubi are smashed.
Elves got in. Crushed by my 3 military succubi.
About a year later elves show up again... this time... 4 ambush squads, 12 man each. 2 full ranged, 2 melee with deer mount. Well... that was something my military couldnt handle clearly. Well took still about 18 melee fighters out... the ranged squad killed my succubi then sadly... and thats the end of my first fortress.
Its pretty fun though.
Gonna do a human embark this time and the next time I go into the glacier and see if succubi can survive there. They are quick to setup and pretty powerfull, just the early invasions are a thing you need to prepare for from day 1.
Also I ran into some kind of issue when I played... quequed milking creatures... and tentacle monsters didnt produce their "slime" after a while so I couldnt give more succubi the torrid kiss ability. Might has to do with the fact that I used Workflow to setup automilking, will test that in a little.
