Q:
Daze ??
Daze prevents all skill use; stun also prevents any kind of movement. Note that there are a few exceptions, most notably stun breakers.
I don’t generally think something both stuns and dazes, but I dont know every single class back to back; most likely if that is the case Daze has a longer duration than stun.
Example: Confounding Suggestions has a “chance” (at 100% currently) to inflict a stun whenever you inflict a daze. Really, in this case, what that ends up amounting to is that you are stunned instead of dazed (and stun is superior). But that trait also has a 5 second cool down, so if you are chain dazing someone it wont always be triggering.
daze is either longer than stun (marginally; exclusions apply) or else stun is conditional, with daze being applied instead if the condition is not met.
