Which Difficulty? With causal it's easier, because of the save inside dungeon. But it's hard to get that. You have to make your way to lvl 2 Maze and to the priest. Take some speed potions with you and try to get to the zombie dragon. Than it gets a bit difficult, you have to lure him out, run inside the room, open the chest, grab the bow and flee without dying.
You have to get threw lvl 1 and downstairs. If you know the way, just ignore the lvl 12 minothaurs and run (evasion and speed helps you). Also on lvl 2, you have to run till the Teleporter, that brings you to the priest, take a big emerald with you, that way you'll get a 12h rest and a save.
