When enabled, players require a "Charge" to get an AngelChest spawned
Charges are like a virtual currency. They can be obtained only through /acadmin charges, so you can sell them to players or give them out as rewards
Additional settings still apply, so if you set a price to get a chest spawned, players will require both, a charge, and the amount of money/item you set
See config.yml (line 850ff. in default config) for more information
