Crafting Reset Foods

Crafting Reset type Sprite foods! These are created at the Sprite Food Machine like all other Sprite foods.
-----
Reset Mote: Resets 1 skill point of your choice. Requires 5 1* materials and 5 of every crystal type (as well as the original crown cost).
Reset Dust: Resets 2 skill points of your choice. Requires 5 2* materials and 10 of every crystal type (as well as the original crown cost).
Reset Stone: Resets 3 skill points of your choice. Requires 5 3* materials and 15 of every crystal type (as well as the original crown cost).
Reset Orb: Resets 4 skill points of your choice. Requires 5 4* materials and 20 of every crystal type (as well as the original crown cost).
Reset Star: Resets 5 skill points of your choice OR one Ultimate Skill. Requires 5 5* materials and 25 of every crystal type (as well as the original crown cost).
The current Reset Star would also be available in the supply depot as it is now, but would have to be renamed.

All foods still make your sprite lose appetite, so there's a reason to craft higher level reset foods.

"Every crystal type" includes Moonstone and Valestone, so this will make them actually somewhat useful.

Maybe reset stars could give an option to reset an ultimate instead of skill points?
I'd say please let any of these apply to ultimates, otherwise a sprite with even 1,2, or 3 ultimates chosen can't use these effectively, and you'd want this to be an option anyway, so you can switch one or two ultimates without having to re-select all three. Obviously a skill that's had an ultimate chosen would reset to default if one of these materials were used on it at all. No biggie and very convenient for ppl who want to see what their sprite can look like in real time. Us editors try to get pics on wiki, but there's nothing like the real deal ya know?
These would be especially good in case a player wants to invest in something specific while leveling and makes a mistake, or wishes to do a damage study without raising or finding someone with another sprite. Yes, this would be very useful indeed, even though eventually a sprite does gain every skill point as it grows. The "any mineral" is a very nice touch. I'd imagine the crafting cost would be more expensive than listed in the OP, considering OOO's current design on the matter...
I think involving rock salt would be very fitting and somewhat economically limiting. Its description is pretty neat, makes it seem like a colorless mineral:
A small amount of Clockworks mineral that's been infused with absolutely nothing. It hungrily draws at nearby essences and flavors, making it a staple in cooking, and the bane of jellies everywhere.
Potential name for "thing that resets all skill points": Reset Platter. It's sorta like subtraction stew from Phantom Tollbooth! Harhar. Hungry for... skill points.
EDIT: Alternatively, simply have only 1, 3, and 5* reset foods. 1* resets a single skill point and can be used to fine-tune a study for any skill as needed or fix a mistake in someone's plans (which isn't a big deal in the long run, but ya know ;p) 3* can be used to reset a single skill entirely for other studies. Both can be used in junction as needed, and of course any ultimates chosen for the affected skill would be reset if either are used. 5* can be used to reset all skill points at once, as it does now. Hunger is somewhat of an issue, but due to the nature of these materials, maybe we can see them have no effect on hunger, as if the sprite were swallowing air. I have a feeling they're only materials for general convenience in the sprite interface, imo, this sort of thing feels more like a "rarity" than a "material."
