So after using him a bit more, I have a better idea of how his trait works. In my experience, the "acclimation" accumulates faster if you drain Joestars, relatively slowly against regular humans, and not at all against Vampires or Pillar Men.

There are 4 levels for his acclimation, where each stat change is more and more dramatic with each level gained (lv 1 - says "Ho ho!" and sparkles; lv 2 - says "Najimu!" and gets a small yellow aura; lv 3 - says "Jitsu ni najimu zo!" and gets a larger yellow aura; lv 4 - speedlines on top and bottom of screen, says "Saiko ni hai tte yatsu da!" and gets a large yellow aura). Each level gained increases time stop duration, increases cooldown speed, increases ATK, and decreases DEF. Basically, he does become a "glass cannon" the more that level increases.
