There are some good axes in the game, slasher for one. I have never used them however so I cant vouch for speed. There were a bunch in the catacombs under aeleroth but there were only two that stood out to me. Dont remember them though. Keep an eye out and if you dont find anything, then use the editor.
As far as killing Stalker and ghost, they are tough but if you have spell capability with limbs of lead, energy cage or freeze and it is high, that is very helpful. In fact , for my mage, who is not supposed to melee, it made many creatures beatable that would not have been otherwise without resorting to scorpion traps.
