These upgrades can interact with a players Ender Chest inventory, but due to the unstable nature of Ender Magic, it only works if the player is in the same dimension as the upgraded pedestal.(Logged out players also can not be interacted with)

The player who placed this upgrade into the pedestal is the one who's ender chest will be used.

When enchanted with the Advanced Enchantment, these upgrades will use the players own inventory and not their Ender Chest.
