Want a fun trick? It's easier to get the ultimate ability for Necropolis and Academy! For Necropolis, just collect the Cloak of Deathly Shadows and 2 Rings of Broken Spirit and equip them (if they are on the map, of course) and use Banshee's Wail during battle.
It's a bit more complicated for Academy – you need to max out all spells to Expert and visit a lot of castles (and if you're lucky, you'll get all the spells there).
True, Dark Elves can conquer 10 castles (of course, Dungeons) and they will get the ultimate ability. That's the trick.:D :D :D :D :D

Well, I wouldn't say so. Sometimes it's difficult even against the computer.
