RageCandyBar was hotfixed and now is described as follows:
This may be activated at the very begining of any action by the player without using the action. When activated, this item is consumed and the Pokemon gains a one (1) rank bonus to Attack, Defense, Special Attack, and Special Defense and a 25% (x1.25) bonus to Speed, rounded up, for six (6) actions or until switched out. If the action is pushed back, so is the activation of this item, unless otherwise specified.
Changes are:
1) Activation happens at the very begining of any action (the first thing to happen) chosen by the user
2) If you push back the action when the activation is to happen, you are pushing back the activation also, unless you specify otherwise on the sub.
this is valid immediately.
