Rhongomyniad, known as The Lance that Shines to the Ends of the World is a Divine Construct that rivals Excalibur in power. Rhongomyniad is sealed by the Thirteen Restraints of the Round Table. This is the same set of restraints that bind Excalibur.
The restraints are: 1. The enemy must be more powerful than oneself 2. The battle must be one-on-one 3. The enemy must not be an elemental spirit 4. The battle must be one against evil 5. The battle must not involve personal gain 6. The battle must not be against Humanity 7. The battle must not be inhumane 8. The battle must be for truth 9. The battle must be to live 10. The battle must be to save the world 11. The battle must be to defend human order 12. The battle must not be against one pure of heart 13. The battle must be an honorable one
After you release a single restraint, it will permanently remain open, allowing you to reach Rhongomyniad's full power after you have unlocked all 13 restraints at least once. Wielding this weapon will slowly change you into the highest-ranking Divine Spirit, giving you a Magical Energy that surpasses space and time, which will allow you to gain control over the flow of time and eventually, time travel. Rhongomyniad has the ability to shape-shift as well. The outer spiral shell of the spear can be shifted into a shining set of armor reminiscent of white bark, this armor can grow branches as an additional form of defense.
