rauru's arm
King Rauru's Right Arm (TotK), also simply known as the Right Arm, is an item introduced in Tears of the Kingdom. It was originally used by Rauru to seal Ganondorf beneath Hyrule Castle during the Imprisoning War, long before the events of Breath of the Wild.
When Gandondorf was awakened, he send out a wave of gloom that ravaged Link's right arm, along with taking away his health and stamina. To save Link, Rauru caught him with the arm and replaced Link's decayed arm with his own, also allowing Link to use several abilities (Ultrahand, Fuse, Ascend, Recall, Autobuild) with the arm.
Please only tag this when the arm is connected to a character that is not Rauru or when the arm is glowing cyan (as in, it is obviously different from a normal arm by the character's standards).
