Atziri's Foible does not reduce Attribute Requirement

Atziri's Foible doesn't reduce attribute requirements, nor is it intended to. You equipping one item can't suddenly change the properties of every other item in the game.

What it does is let you equip items as though they had reduced requirements. The item still has it's requirement, but you only need 75% of that attribute requirement in order to equip and use the item.

The stat description as implemented explained that - it said "Equip Items and Gem as though they had 25% reduced attribute requirements", but it looks like it's been changed and is now incorrect. I will investigate.

EDIT: This was changed while I was away to make the description shorter and less wordy. However, the current description is inadequate, as anyone reading it would conclude the item is bugged - just like you did, as it clearly says it does something that it equally clearly does not do.
We're now considering ways we can get the full meaning across without it being too long (any suggestions from forumgoers are appreciated!)
Personally my first thought is to remove the "and Gems", which is unnecessary because gems, by definition, are items, but apparently that was tried and confused people.
