Premium Transformation Stone Success Rate?

[Ventace]

Can a dev disclose the ACTUAL success rate of Premium Transformation Stones? Lots of people say it's theoretically 50% but a vast majority of people get 20% or less. Personally I have about 25% success rate. Why keep it hidden? It's already a risk, why not let us know the odds we're faced with if we take the risk?

it's about 20%

Originally as stated by ncsoft in a stream the rate was 30%. They later on increased it to if I am not mistaking 40%.

[Granger]

The statistics i collect point to about 40-30% success chance.

It's pretty bad, only craft them when you don't mind losing material.

Did 4 on 4 this week, never missed more than 2 when I try about 6-8 at time, always heard about 50%, i don't know..

The last official statement was that it was raised to 50%. That has been over a year, though, so I can't be bothered to dig it up. Unless they ninja-nerfed it like they did with Naksun, it'd still be around every 2nd try. From my last 10 transmutes I had 6 successes, so it seems to check out.

I tried about 40 times in 3 months. Got about 13.

I used to get around 50% chance before the June patch. I think they ninja nerfed it. Now I just buy PTS and sell the materials

30-40% ???   i guess that why i failed 8 times in a row ....  lost a lot of gold and resources for nothing.
