Just had this as a sudden thought, felt that it might actually be pretty cool. I was thinking it could be something akin to the Lickilicky except it costs money. Maybe that Froslass or Snorunt NPC in Winden could be the one to do it? As far as price goes I was thinking maybe 1k, 5k, or 10k to freeze the player’s entire inventory (Apples become Frozen apples, big apples become frozen apples, leppa berries become frozen as well).
What do you all think? Personally I’d honesty use this feature if it was a thing. Grimy traps can be annoying and a way to deal with them that costs a bit of money (and a reduction in the effectiveness of how much Belly they restore) sounds like a good trade off to me.
