Lockbox

Lockboxes is Neverwinter’s microtransaction lootcrate system. The lockboxes themselves drop frequently from the world, but keys to open them are only available in the cash shop. Each major content update usually releases at least one lockbox with unique and often exclusive rewards. The best ones only have a small chance to ever drop. Players that want to get specific rewards have to open hundreds of boxes to have a decent shot at getting it.
