I have a question about candy canes and gift boxes (Holiday Cheer). Will these persist after the Winter Event ends? I was thinking they'd make nice prizes for Costume Contests, something we could actually give to winning contestants.
Yes, those persist, as do the special gifts found in boxes (
FrisbFlying Disc, Toy Bat, and the LKT Rocket Pack). The only things that expire are the Snowball and the Holiday Rocket Pack (aka Jingle Jet).
There isn't a trade system, so candy canes can't be given away, but any Holiday Cheer and Mystery Gifts you've stocked will persist. Those stack up to 99 charges.
Once the Candy Cane vendor is implemented, I was considering making Mystery Gifts available for people who wanted to do a random roll instead of outright buying the temp powers. I suppose I could also add in Holiday Cheer boxes to that for if you want something that can be given away.
Long term average for getting candy canes from Mystery Gifts is 3 per box (once all the other items have been claimed), so that's the absolute minimum cost to avoid an infinite candy-cane generating loop. Somewhere around 10-15 candy canes per box sounds reasonable, maybe with the version that you give to other players being discounted.
