the sdkillup tweak was for MOBS that check DC to your skill. Look up your next levvel cap in the skill caps chart, then find mobs that spawn at least DC to that level and up, and go spam spells on them. I do this and get lots of .3-.5's that way--even without kupower up. Sky dolls were great for me to get to 300-305 on most all weapons. Glen crabs in Grauberg abby work nicely too sometimes.
