First: Permanent ones... Probably really expensive. 50x the price here, except the Heat Amplifier.
Not sure about the heat and krogmo coin boosters though, just putting the prices out there if you decide they should be put there.
Maybe...:
Permanent Trinket Slot Upgrade: 7500 Energy
Permanent Weapon Slot Upgrade: 12500 Energy
Permanent Krogmo Coin Booster: 15000 Energy
Permanent Heat Amplifier: 40000 or 50000 Energy
Then - New upgrade usables, boosting Sprites slightly.
Allows you to very magically have your Sprites do things without you making an actual command, magically. (Allows you to use a sprite skill while still using a different action, e.g. charging a weapon or attacking. Sprite skill animation is still played if a sprite skill is used while not using a different action. Regular lasts for 30 days.)
