We were stuck on 99.9 (on cursed soups) for what seemed forever. I had some dragon meat from a KS99 we did a few days earlier, 1/1 Red Curry = 100 Cooking. Our jaws dropped when we saw the skill up message scroll up.
I'm personally stuck at 99.7. I've been far too lazy to farm the jellies to finish it off. Plus I farm the Rolanberry/Crawler pop NM's and not the bees.. 3 hours of killing pop NM's, walk away with 10 jellies and 0 skill ups. >.>
