Oridys's Rise: Seek three wise beasts
In order to gain entry into Oridys's tower, a hint is provided: Seek three wise beasts. This refers to tortoises that are located in and around the area. Find all 3 of them and attack to destroy them. There's one in the bushes in front of the tower, a second behind the tower, and the third one is invisible located in the rear pond. Just attack the area that splashes to reveal him.
