Stellar Battery item
Stellar Battery is a passive item in Heaven's Call, a mod for The Binding of Isaac.
Description
Using an active item discharges it and spawns an item spark.
Item sparks behave like active item wisps, triggering the item's effect when destroyed.
If the active item is used without enough charge, the oldest spark is consumed instead.
The more charges the item has, the more health the item spark receives.
A maximum of 27 sparks can exist at once; if a new one is created beyond this limit, the oldest one will be consumed.
Does not work with self-rechargeable, cancelable or no-charge items, with the exception of:
