Congratulations, you've got a permanent Decent Skill. Please note that if you equip another Decent Skill equip, it will cancel out the glitched Decent Skill and you will have to do it again. It's advisable that if you can get your hands to this potential equip, do this glitch ASAP as you don't know when Nexon will patch this.
