Most of the time I have about 1300 sp's.
I dont 'sp farm'. I do 'sp procrastinate'.
I'm just so carefull when spending them, I dont jump the gun on anything.
I usually spend them when I notice things are getting way to hard to kill. I'll put a few more into both my bow skills, and a little into lightning, untill things are back to normal.
When I level again, more points are going into Spirit Bow

THWAK! When SB crits and kills monsters in one hit, I am happy.
I am still waiting for an absolute answer on Mind Concentration. If it really does increase speed, I'll be spending.
....And a few new peices of armor are comming out of storage.
