It would be great if this worked, bug or outdated?
I've equipped several items with this type of description, such as 'Crit Boots,' but I don't notice any changes in the game after doing so. Despite having multiple items with similar descriptions, equipping them doesn't seem to have any noticeable effect.

That’s outdated item information. Prior to en enchanting items like vozuth armour had base stats, which was crit in that case.

You should hover the item and see what secondary each item gives rather than reading shop item details.
