Physical Strength can be maxed too.
Whirlwind and Boomerang maxed for stages.
Force is awesome ok, level 1 at least.
And imo 0, 4, 8 for Party MDef. 4 because it only costs 1 pearl and 1 rope, anything past that = more reagents.
I think scratch has to be at least level 2 to do some decent combos with it
Also ive always wondered: max disturbance = more time for control switch or no?
