Os três desafios foram :
The Breath of God - "Only the penitent man will pass"
The Word of God - "Only in the footsteps of God will he proceed"
The Path of God - "Only in the leap from the lion's head will he prove his worth"
Indy usou o Diário do Graal do pai dele para guiá-lo pelas armadilhas:
The Grail Diary was a possession of Doctor Henry Jones, Sr. In it, he recorded all of his findings on the topic of the Holy Grail, the study of which he had made his life's work.
He did many travels between America and Europe, contacted many scholars and sought several historical documents during his studies, always carrying it with him.
Indy's knowledge of his father's research in the diary helped him slip past the traps in the Grail Temple and recover the Grail to save his wounded father.
