Can't carry much extra weight because I replaced the leeched unholy, so I wanted something very light and unlimited.

There are better unlimited weapons but few that are as light and unlimited.  I wasn't expecting to have to fight 4 enemies together with it, because normally the enemies don't stick around long enough to link up during my hours which are generally quite quiet.  I know that in practice there were never more than 3 of them on me though.
