The Hall of Trials is a location in Xenoblade Chronicles. It is located in the High Entia Tomb. It is above the Tower of Trials, which is guarded by an Orluga Rufus on each level.
It can be reached by walking east from the Hall of Spirits or the Tower of Trials - Bridge (and then walking up the levels), or west from the Ceremony Hall.
A Heart-to-Heart - "Hopes and Plans" - is located here.
