I play a lot with Yellow Jacket and I really like to use power sting.
When an enemy has power sting status and he tries to cast a special attack, he gets punished by causing damage to himself. However when he is about to cast a SP3 (level 3 special power, meaning when he has a full special bar) sometimes the power sting hits before the special move and sometimes after it.
How do I know if power sting will hit my opponent before or after he casts a SP3? Does it depend on the targeted champion?
