<includeonly>=</includeonly>==Effects of Evolution / Fusion on IVs and EVs==<includeonly>=</includeonly>
Please note that Attitude randomizes when you evolve/fuse a Yo-kai, so if you're training them specifically, pay attention!
'''[[Fusion#Fusing 2 Yo-kai|FUSING TWO YO-KAI TOGETHER]]'''
IVs will be re-rolled, IVs of parent Yo-kai do not matter. EVs are carried over, I am not quite sure if it's one parent, or somehow both, and if it IS one parent, I'm not sure how it picks which one it is. Recommendation: Fuse ONLY untrained Yo-kai to prevent this confusion. Also, note that the Attitude will be re-rolled as well.
'''[[Fusion#Fusing 1 Yo-kai and 1 Item|FUSING YO-KAI WITH AN ITEM]]'''
IVs will be re-rolled, IVs of the original Yo-kai don't matter. EVs are carried over, but as mentioned above, the Attitude might change on fusion so pay attention.
'''[[Evolution|EVOLVING YO-KAI BY LEVEL]]'''
IVs sill be rerolled. EVs are carried over identically, but as mentioned above, Attitude might change so pay attention.
