An example is Dark Homunculus s3 Unbalanced field:
"Increases the skill cooldown time of all enemies by 2 turns each and decreases the Attack Speed for 2 turns. After that, the skill cooldown time of all allies will be decreased by 2 turns each and the Attack Speed will be increased for 2 turns."
It is an AOE effect skill that does not damage enemies. Or Zen wind shadowcaster s3. Would they have chance to stun enemies when using Despair? Or it only works with AOE skill that deal damage?
