Soul Blazer/Character attributes

By the time you get all of the Soul Equipment you should be Level 24-25 (otherwise The Soul Blade can't be used). At 25 your strength and defense will be maxed. You may train further to Level 37 to get more Hit Points, which will be useful against Deathtoll, but to reach Level 50 is unnecessary, since you need to spend a lot of time to collect Exp (the difference between Level 25 and Level 50 is 99,849,999 Exp). You may even spend a month grinding to reach Level 50, which is not useful since your HP maxes out at 100 at Level 47. On the other hand, reaching Level 50 is like getting a special trophy that not every can get.
