Others here might disagree, but I found a melee warrior the hardest of all the characters to play in the catacombs. Later on the warrior will do much better. Anyway make sure you carry potions with you, and set 1 of your tp stones next to a bed in Aleroth so that you can tp there and sleep as needed to restore health. Gregar the zombie can be of help to you too, but he will take exp points away from you if he lands the killing blow instead of you. Save often. You might die and have to do some parts over. Remember to use your special Warrior skill when you get surrounded, but it is better not to get surrounded and take on enemies one at a time. The Slasher Axe is in a small area which you enter via a floor tile. Proceed cautiously when you go in there and try to avoid engaging more than one or two skellys at a time. If the big guy in there is too tough you can always run past him, get the axe and then go back and kill him later when you are a higher lvl.
