Testament of My Failure is a seven-part tome found in Adventure Mode of Diablo III in Act V on Greyhollow Island. It is written by Rayeld / The Crazed Man, and drops from the satchels randomly found across the island (on surface and in the Ancient Tower).
Once both tome parts are found, touching the subsequent satchels will open a portal to Forsaken Repose.
It reads as follows:
- Everyone is calling me a hero now. If they only knew. No hero does the things that I have, and for what? They think that I have freed them, but I have damned us all.
- What I am about to do will torment me forever. But I have no choice. It is my fault, therefore I must set it right and do whatever it takes to keep this evil from spreading and poisoning the whole world.
