Ooh, I see where my wording may have been confusing. I never thought Raid Power gave me different items. By the predetermined items, I was asking if the rewards were set whether or not I had raid power, as in I wouldn't have the opportunity to get additional items with raid power, not different items.
So based on your answer, if I were to run Raid Power with a pre-existing raid on the map, I would have a chance to get more items, even if I didn't get those extra items without Raid Power. Correct?
Also, do you happen to know how many extra items you get with raid power? I saw you mentioning 36 item stacks in chat when testing with Ax? What's that about.
The rest of the answer is fine, thanks for testing that. If it seems like I'm hammering you, I'm not, I just want to know the ideal time to pop a Raid Power sandwich for farming things like Herba Mystica, especially with these Magikarp raids going on. My main question is essentially "would I get Herba Mystica with the extra items given from Raid Power if I didn't get any without Raid Power," and if the answer is no, then it's better to just make the sandwich and reroll my raids.
I hope this makes sense as to what I'm asking. I will give you BA after that gets a concrete confirmation.
