Restraints of the Round Table

The Restraints of the Round Table (円卓拘束, Entaku Kōsoku^?) are thirteen restraints set upon King Arthur's weapons by the Knights of the Round Table, applying to both Arthur Pendragon and Artoria Pendragon. Excalibur Proto for Arthur and Rhongomyniad for Artoria possess the restraints. As stated in Artoria's Interlude in Fate/Grand Order, her Excalibur also possesses them, and it does bear similar conditions to activate its most powerful state.

For Rhongomyniad, over half of the restraints must be released in order to release its True Name. For Excalibur, each condition passed allows for more power to be utilized. For Excalibur Proto, over half of the restraints must be released to achieve a perfect release of its True Name, but even with less than seven restraints released, a weaker release of its True Name is possible.

It is unknown if every single condition is shared between all the weapons or if they vary depending on the world.
