Does anyone have any idea on a price for this? There are none in shops and only my one in trades? Thank you

There is a price check board here for it.

But it's from over a year ago.

I would compare psycho smasher with that is selling in shops for 65 mil. Psycho smasher does more damage but has less %chance freeze than shriek and blocks ice instead of wind. Based on my own experience with the freeze rate of the scroll, I wouldn't pay more than 50 - 65 mil for it. That's just me though. Maybe would know better?

I'd price them similarly with shrieks too, especially with the knowledge of when the reset happens, psycho smashers will be able to be obtained from more than just the achievement. some people prefer smashers, others prefer shrieks, so they're probably about the same.

Thank you all x
