This ring is not a physical weapon in the traditional sense, but rather a tool that grants the Green Lantern the ability to create hard-light constructs. They can manifest anything they can imagine, within the limits of their willpower and the ring's power.
Some common constructs include:
* Energy blasts
* Force fields
* Flight
* Weapons like swords, hammers, and shields
The ring is powered by the willpower of the Green Lantern, and its effectiveness depends on their mental fortitude and ability to focus.
