So yah I was think about it and I’m guessing stuns stops people from attacking at all but silencing just what? Stops the skills from activating? I think there is one more but I can’t remember it can you help me out?
Stuns stop enemies from doing anything for the duration. Silence stops skills but they can still use their basic attack. Freeze works similar to stun, except in Frozones case where it damages them as well. Scare and study do not cause negative effects, but allow you to do more damage.
The picture on this thread hasn’t been updated to include the new stuff, so I’ll type them (+ a couple) here:
Stun = stop an enemy from doing anything
Silence = prevents Fantastic skills from activating
Curse = prevents healing (except Life Steal)
Scare = allows Fantastic moves to crit
Study = allows Normal moves to crit
Other debuffs can be found in-game, as well. During a fight, pause the game & press the 
button. This will take you to the Combat Status Icon screen.
Silence should be any activated (non-passive) skill, not just fantastic
Oh right, my bad! This.
Thanks for the help you guys!
