'''TL;DR''' If you're a min-maxing soft-resetter, aim for highs of the high stats and lows of the low stats.
==Evolution and Fusion==
{{see also|Evolution|Fusion}}
Just like befriending a brand-new [[Yo-kai]], evolving or fusing Yo-kai creates a completely brand-new creature. The stats/Attitude of the pre-evolved or pre-fusion monsters DO NOT MATTER. Once the evolution/fusion happens, the stat ranks are re-rolled for the new Yo-kai, and they are given their "default [[Attitude]]".
In many cases, it is wise to fuse at as low a level as possible, so that you have the most influence over the resulting monster's Attitude level-ups. A lot of Yo-Kai have HP-increasing Attitudes at default.
