Not only could the Tattered Treasure Bag contain legendary equipment but those who opened it also had the chance to obtain Skill Points and Attribute Points. As long as you had a fishing rod, it was not necessary for you to seek for fishing spots. That was because there would be a definite probability that you would be able to hook something up even if you cast an empty hook into the water, even without placing any fishing bait there. If you had great luck, you could hook all the fish in a few minutes. However, if your luck was even just a tad worse, it would take about 5 or 6 hours.
Of course, since it was extremely easy to obtain Skill Points and Attribute Points, the number that they could obtain was naturally limited. The highest number of Skill Points was 2 while the maximum number of Attribute Points was +1 for each ability type. Once they had capped this limit, they could only wait until the next year to get more again.
