All castles in Heroes 3.

Water has a number of cool spells! But 3 magic is overkill... I always take logistics, often ballistics, wisdom always, mysticism almost always too... And Dess starts tearing everyone apart!

Mysticism rules in WoG, but in vanilla 3 I almost never take it... Ballistics I NEVER take!!! (I don't need it for shit, pardon me—shooting units will do the job anyway!) Logistics or Pathfinding I always take, and I also like Intelligence... In short, I take roughly this set: 3 magic (except fire), wisdom (usually there from the start), logistics (pathfinding), intelligence, and in the remaining 2 slots—whatever is useful... If available, I definitely take Archery... Well, one could also take Offense or Defense if given (which, same for mages, isn't that common, but happens)
