I know rare and super rare items are guaranteed to give you a fragmentizer crystal. However, are normal items more likely than common ones to create a crystal and things like that?

As far as I know, these are still the chances: R65 and under: 0-1 crystals R66 - R89: 1 crystal R90 - R98: 1-2 crystals R99: 1-3 crystals

R160 + R175 give one crystal each

there is no increased or decreased likelihood for anything below r65. Each item below r65 will have a fixed chance, based on the item itself, I think it gets randomly generated once per day or once per week, but it stays consistent for awhile. This chance used to vary from one in three to one in six.

Recently numbers had been changed where all items below r65 gave nearly one for one. I haven't checked the odds since they stopped doing this so it may be back to what it was or something different.

I only have today to go on, but I really doubt it's roughly 1 for 1. I was getting a bit shy of 1:2

I didn't write that with bad grammar, it used to be nearly one for one for a few months. This was temporarily true for all fragmentizeable items below r65 when the r160 and r175 crystals were made Fragmentizeable. Those rarities didn't used to be able to fragmentized. But some users complained about the price of Humming Power Crystals. The price of HPCs isn't the purpose of the Fragmentizer, but whatevs, so now the odds are not nearly one for one anymore.

It's been awhile since I've done any fragmentizing, I have a huge stock of crystals right now as I had dumped a whole chunk of non-sellers I was hoarding into the machine. These just shy of one in two odds you are getting, is it for all items?

Good to know, thanks! I was only bothering to frag R normal and above items because I didn't know if mundane ones worked or not. I want to get ahold of crystals so I'll be fragging soon--I'll separate them by rarity and see what happens. I'll keep you posted :)
