Catching up on my Morostide battling, and I got two more Shrieks. Bringing my total up to seven.
Three are in my current default scroll set. Pacifist has a total of 182 AP. Wondering if I should put some more in there because boy do I love a good chain freeze.

bird and bear and hare and fish give my love her fondest wish
I would make a freezing set and remove the scrolls that don't freeze - cobalt and the gale force scrolls. I would even remove the perilous whirlpool if that means being able to equip another shriek. If your pet has high speed, I would swap out the gelaspell for unstable fairy. You could also make at least one cold blast scroll from beating daemon and mama mush 75 times
With 182 AP, here would be a good freezing scroll set:
