This trial dedicated to the War Father can only be accessed by scanning the Alm amiibo. Within, you can battle 5 enemy groups that get progressively stronger to reap rare and exclusive items.
The doors ahead will only open after defeating the enemies keeping guard. Normally the stone tablets contain a passage from the Book of Valentian Revelations, but if your party’s Rating is too low, they will warn you not to proceed.
Each boss drops a rare item, but only once. After clearing the whole trial the first time, you will receive a Silver Purse++ and Duma’s Helm.
