use event materials for sprite food

there's no way I can make 18 Winterfest weapons with 208 giftwraps.
have the ability to use the materials for food, but with the following changes:
- double material requirement when using event materials to craft sprite food. could result in a separate food thing (power star vs (EVENT) power star)
- subtract double appetite when feeding directly to the sprite
- give a prompt when doing any of these (are you sure?♫!.¿¡1)


And the point of using event materials rather then normal ones is...?

Because you can't sell the event materials to other players who need them, and we might have a very large sum of 5* event materials that we will never use.
"I can use my reaper ribs to make a weapon, but cannot use my indestructible giftwrap on anything but a reskin."
My personal solution is to just sell the materials to vendors, but if you're leveling a sprite up then I understand completely.

You can't feed sprites useless event mats? Wow. And I thought bound rarity drops and unbound bought rarities was a bad idea.
