As I was doing the battle tower, I noticed that there was some getting past a few mons, without realizing that some of them had the move Curse. Curse is a split between normal and all other pokes besides ghost types. This issue I am establishing here has to do with normal and other mons, not ghost type Curse. It may not seem like a big deal, but Curse for some reason is gaining +2 in atk and +2 def, and -1 in speed. Curse is suppose to only do +1.5 in atk and def, and -1.5 in speed.
Here is my other source proving my statement.
Hopefully more moves will be tested more and completed correct! Thanks.
