When I was fight the boss Papulatus with a friend I wanted to try our Super Transformation. I was immediately turned back to normal because pap had dispelled the skill. This was around 1 week ago and I have been lazy sorry for not reporting it sooner! Solo
Yes, Its suposed to be on the entire 120 Seconds starting from when you use it. It was this way in GMS, I used super trans on my Bucc all the time at Pap and he never dispelled me, same goes for Pianus.
