Obsidian "Earring" bug
I purchased a ring from Windwalker Fai Byeol in the World Serpent Inn.
The item claims to give a +2 bonus to hide and move silently.
Upon equipping the item, the bonus is no longer listed in the tooltip, and my skills do not increase.
Upon moving the item into my inventory, the tooltip corrects itself.
Verify that you do not have any items that give a +2 bonus or higher to the indicated skills. Skill bonuses do not stack.
Was not aware that was a thing. Money well spent.
