It somehow went unnoticed by the entities that your Shard had the ability they sought for eons: it defies entropy. Somehow your power allows you to defy entropy and uses this itself to keep it charged. You will never run out of energy. This is more or less useless unless you're either immortal or think you're capable of convincing the entity to leave behind all his other Shards, including Sting, and therefore not kill all humans in exchange for your Shard. A Shard without this perk may still have the ability to defy entropy, but you need to find it yourself because the Shard doesn't already know.

Entity Energy Generation
As an Entity, you have knowledge of how to defeat entropy and generate energy ex nihilo (out of nothing). All of your Shards are capable for sustaining themselves indefinitely and produce buds during a cycle.
Without the Feeder cluster, your growth is very limited until you develop better energy generation capabilities.
