According to the Encyclopedia Updated, the shields could remove gravity entirely from a large area or increase it up to a thousand times.

Frequently asked questions
- What is the Gravity Shield?
- The Gravity Shield was the signature elemental tool of Nuhvok-Kal, one of the six Bohrok-Kal. It allowed its wielder to manipulate the gravitational pull on a target, increasing or decreasing weight at will.
- How did the Gravity Shield work?
- The shield served as the focus for Nuhvok-Kal's stolen gravity power, able to strip gravity from a large area or increase it up to a thousand times. Like other Bohrok shields, the pair could also be used to block or strike.
- How did Nuhvok-Kal use the Gravity Shield against the Toa?
- When Tahu Nuva sent a Tahnok swarm against it, Nuhvok-Kal flung the Bohrok into orbit and then raised the gravity on Tahu until he was helpless. Near Le-Koro, Tahu and Lewa later wore it down with the help of Le-Matoran who pelted it from every side.
- What was the Gravity Shield's purpose in the Bohrok-Kal's mission?
- The shield was deployed as part of the Bohrok-Kal's mission to steal the Nuva Symbols and use them to free the Bahrag from the protodermis cage the Toa Mata had sealed them in.
- How was the Gravity Shield destroyed?
- On Gali's plan, the Toa Nuva channelled their elemental power through the Nuva Symbols into the Bohrok-Kal, giving them more than they could control. Nuhvok-Kal's gravity overloaded into a miniature black hole that destroyed it, and the Gravity Shield with it.
