Starting from the cathedral where you pray for blessings and abandon evil, attack the wall behind the treasure chest and open the hidden road.
Jump all the way along the tombstone and the board. At this time, you can find an old man playing the piano and rubbing on the sarcophagus below him.
Gently jump onto the second sarcophagus. Key point: Don't run faster, just jump to the side normally. Try not to touch the wall.
Reaching the bottom is the blessing of "epilepsy seal". Remember to be lucky, but don't take off your clothes first. It's too late to wait until the last boss is finished.
Please note that in the game "The Ring of Eldon", the blessing point of epilepsy seal needs certain skills to reach. The above steps are for reference only. It is recommended to consult experienced players or consult the game guide to get accurate information.
