Affliction Guard protects the user from becoming afflicted when hit, up to a certain amount of times.
While this effect will block afflictions, it will NOT block the user from taking damage.
This effect also will NOT block debuffs such as ?'"`UNIQ--item-73009--QINU`"'?, or special effects such as ?'"`UNIQ--item-73010--QINU`"'?.
Note that one stack of Affliction Guard will still be consumed if the user is hit by an affliction they would have 100% resisted anyway.
For example: ?'"`UNIQ--item-73011--QINU`"'? has 100% resistance to Blindness. If she is hit by an attack that could inflict Blind, one stack of Affliction Guard will be consumed. This would essentially "waste" a stack of Affliction Guard that could have blocked a Paralysis-inducing attack instead, which Alex does not resist.
If a ?'"`UNIQ--item-73012--QINU`"'? or ?'"`UNIQ--item-73013--QINU`"'? successfully nullifies an attack and its attached affliction, that attack will NOT consume one stack of Affliction Guard, as there is no longer an affliction to block.
