Champion Belt (VII) increases critical chance

So after this tweet by u/ElNinoFr and my subsequent conversation with him, i decided to check if the same holds true for global. And yes, a Tidus with only the Champion Belt equipped has a 3% crit chance, if i add a weapon that chance rises to 6%. So it adds 3% crit chance.

Not sure if it's worth it, that would be a case for Math. But it might hold true for other accessories. If nobody has checked by tomorrow and i have some free time i could atleast check some of the accessories. Would update then.

Edit: Checked all the accessories that give ATK (and that i had) and none of them had that crit bonus. I think it's safe to assume only Champion Belt has it.

List of all accessories i tested:
Vossler's Gauntlet (XII); Aries (FFT); Crystal Orb (VI); Omega Badge (V); Fury Ring (VII) sorry Pintbox; Power Armlet (IV); Black Belt (IX); Hyper Wrist (VIII); Bacchus Wine (II); Muscle Belt (X); Woft Earing (VII); Black Belt (VI); Godo's Mask (VII); Bracer (FFT); Hyper Wrist (VI); Durable Power Wristband (XIII); Power Belt (IX); Coral Ring (IX); Power Glove (X); Ruby Ring (XIV); Power Armlet (V); Cloud's Googles (VII); Bolt Ring (VII); Muscle Belt (VI); Silver Specs (V)
