So...

Providen...You should know cabal by now. Seriously. I have failed twice in a row to slot something with 84% chance of success. It's literally pure chance always. doomer is correct about probablility. There is NO guarentee that after 8094 tries there will be one. That's how probability works. It simply means that it likely. Not it will. There's a distinct difference, and Cabal tends to run on the lower sides of things. I've spent 6b to +15 1 forci item, and spent only 30m to +15 a redosm item. So it's literally pure luck.

Providen...You should know cabal by now. Seriously. I have failed twice in a row to slot something with 84% chance of success.

I failed to slot the third slot of a helm with 99% success rate. Luckily, rate was in the first slot so I didn't lose it.

I've also had an item go poof with a 90% chance to unbind it.

If it wasn't for bad luck, I'd have no luck.
