LOL sooo easy, pick diana and goto the city to the right of her hometown (tiflis) you will see they have the best katars and armour, well good ones anyway. So ask for quests (try changing the quests until you get a rogues one) the more money it gives the more harder it is and more likely you will get a lvl. Just make sure you buy potions and go back to your hometown and buy some soldiers. And then just keep upping the attribute in which you need for the armour/katars for example katars is DEX. You get lvls very easily at the start and you will very early get the best equipment. You will be able to buy this equipment with the starting gold you get (20000) AND the rogue quests money. Oh and btw the far east empire KO move (forget the name) will do ALOT more damage to you with your armour equiped so just remove your armour to easily beat them.
