Secondary skills in Heroes 3.

Rukh, are you sure that the creatures guarding the mines will actually join you? Especially if your Diplomacy skill is not yet well-developed, and your army is not that strong...? Personally, I think it's in a Barbarian's nature to have expert-level Air Magic (without acceleration in battle, the Barbarian will likely be defeated by a Mage), Attack, and Logistics (to move even faster across the map). All other skills are, of course, also welcome, but these, in my opinion, are the most important. You definitely need to have them... By the way, I was very inspired to play as a Barbarian in Heroes by the song Manowar - Fight until we die :D All true Barbarians must have it, and the image of Manowar is truly "barbaric." I highly recommend it... :)
