Well, I never have tried that before - dungeon leveling. Last time I leveled a character, I used the Zygor guide, and what I liked about that guide was how intelligent it was. It would tell you to take specific quests, and would skip you over other quests. The idea is that some quests take more time than they are worth, and that doing some others are the most efficient route. Well, I'm level 5 right now. It's been a long time, but what's my first dungeon? And at what level might I do this?
Level your hero. You need to start leveling him from the moment you have 2-3 units. This isn’t necessary. If you have KotG, DH, BM, FS, or AM you don’t even have to wait for units. However, with the help of units, your hero can very easily overcome creeps. Among players there is a certain understanding – creeping. Creeping is the destruction of neutral units in order to gain experience. If you kill a creep you earn gold. A gold number and a plus sign will appear on the screen. Sometimes, you need to kill them in order to earn more gold for building purposes.
