[AzurePheonix]

Ok so seeing as my "search forum" feature isn't working can someone please post up the "Amp. Formula" by which i mean how much attack does 1-7% amp actually make up? how much Amp. is actually needed to make a difference in battle?

Well. Think of it like this. Say you have 1000 attack. That means if you have say 5% s amp. You get 50 more attack because 5% of 1000 is 50.
Amp only starts to make a noticeable difference late game, when you have a high base attack of say 800+ or something. (Base attack without buffs.)
