Sleep Resist

Sleep Resist is a gem effect in Xenoblade Chronicles. It adds a percentage chance that the user will not be affected by the status.

Overview
Sleep is not a particularly bad status all things considered, since one instance of damage ends it. But in some situations it can be quite the problem, such as if the whole team is asleep and the one with the aggro is way over there and not controlled by the player. Being able to shrug it off, and thus wake everyone else up, is a great boon. There's no particular character that needs it more than others, though only the player can wake up teammates.
