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.
==Formula==
'''Stats Formula''':
parameters:
x, y, z: three IVs (I call them IV_A, IV_B_1 and IV_B_2 respectively.)
e: EV (attribute bonus)
l: level
B: base stats
(assuming Yo-kai grows at medium speed)
[HP]
HP = floor(e * (1.0 + l * 0.0050505) + (B + x + y) + (B + x + y + z) * 0.1 * l)
[Other stats]
stat = floor(e * (1.0 + l * 0.0050505) + (B * 0.1) + (B + x + y + z) * 0.05 * l)
* Note all calculations must be done using 32 bit single precision floats.
