Tactics for playing as the Dwarves.

A ballista for a dwarf is certainly good... but it's a bit of a hassle to use, the damage isn't that great compared to demons and orcs, and it costs 4500 gold in the forge. In some ways, education helps, as it's not too difficult for a dwarf to level up. A cart is a must-have, definitely.

Education, in my opinion, is also an important perk. Firstly, it provides mana regeneration, as dwarves don't have much mana. Secondly, it allows you to unlock secrets, which is a great way to get evasion, wall of fire, and fireball for priests. Also, you almost always need to level up magic for a dwarf, as 50% of his stats are magical, and if he doesn't have magic, they go to waste. I really enjoyed playing with Chaos; the dwarf deals noticeable damage, but lacks spellcasting for complete satisfaction, so you could choose Erling in that case. I haven't tried playing with Light yet, but the dwarf's lack of attack is very noticeable, so a mass punishing strike would be just the thing, especially against "shooting" races, as I already mentioned, along with mass evasion.
