Taking of the Necropolis [COMPLETE EDITION]

I can't really imagine taking the Cove without Cassi. There are too few units. It needs to be tested. However, it's easy to add a Castle and a Swamp (Draken) to the list. It's a bit more difficult to take a Dungeon against zombies at speed 4 (if it doesn't one-shot them, of course). There are obvious difficulties with the Tower and Necropolis.

I mentioned the Castle; even Vista can take the Swamp without losses. It's definitely not a good idea to attack a Dungeon on level 1 with Shakti. If Adel comes or there's a blessing in the Sanctuary, it can be taken with archers. As for the Tower, if Josephine is the starting hero, a Barbarian or a hero with ranged attack/damage will do. I haven't personally tested anything to find the ideal strategy. In my own games, I haven't noticed any problems with the graveyards.
For the Cove, the usual losses are 1 pirate, 2 sailors, and some basic units.
