Bugs

• The long rest cooldown restriction on Arcane Battery is per character, rather than per item. As such, Arcane Battery can be used repeatedly by passing the weapon possessing this feature to different characters, activating it once on each.
• Arcane Battery is still consumed if active when the character casts a cantrip, despite cantrips not being highlighted in the character's cast bar.
• Toggling Arcane Battery highlights some abilities and items that do not consume spell slots, such as  Danse Macabre and spell scrolls; these abilities and items activate properly, but are still consumed (along with Arcane Battery) in the process.
