HO's at 93 with no mobbing capabilities is a painful grind. = /
I'd personally suggest getting the most damaging weapon you can find, a normal fist may work although I've never tried it with just that.
Go get the skill Occult Impaction to full level, then go to Turtle Island and make your way into the actual dungeon (north)
Once in there, use OI on the turtles there, I think they are all aggressive so they will mob you except permeaters, permeaters should be killed first if you see one because they heal the other turtles and themselves and if your damage isn't so great it'll be hard to outdamage the heals.
That should be good, if you feel confident you can climb in levels, the top level however can get a little tough, if your at the top level keep in mind that for assaulters and wanderers you'll probably do more damage with finger offensive.
If your having alot of trouble staying alive (although, you really shouldn't) get the skill blade stop and get yourself a fire weapon or get a normal weapon and have somebody give a fire endow. Now go to ancient mummies (pyramid, last floor) and use blade stop and then finger offensive, then keep doing that untill it dies.
There are much better alternatives, however this method will gaurantee you a steady rate of exp, perhaps if you provide more detail into your gears I can make a better assumption as to where you can level.
