So, When dark souls came out, it had an item called ring of fog (if you havent played dark souls, it is an item that lets you become near-invisible, and you cant lock onto target. The item is a tad over powered, and is probably the most abused item in the game. It makes backstabbing luck/lag based instead of skill based, and RoF makes mages the next thing to useless. I personally dont have anything against ring of fog if it is used by someone whos, for example, playing a ninja like character wearing 2 claws as weapons. But when someone who wears heaviest armor in the game uses RoF, it just doesnt look cool, and is overall stupid. So how is fromsoftware going to nerf RoF? Making it possible to lock on into RoF users. May not sound like much, but makes the ring more of a suprise tool, rather than direct attack item.

TWoP (tranguil walk of peace) on the other hand only makes moving near impossible, slowing you to the point of walking, and you cannot roll, however the other payer can
