|Complete “Delivering The Truth” and wear the Epsilon Robes.|
Here comes the fun part. What? You didn’t think it would end there did you? After talking to your cult friends in the Grand Senora Desert, they’ll instruct you to wander 5 miles in the desert wearing your powder blue robes. You can sprint, jog or simply walk the distance but either way, it must be done.
If you have good stamina it is quicker to sprint the distance though the constant spamming of the sprint button is definitely a test for your thumb.
After finally completing your trek, Cris will call you asking you to bring a “generous tithe” to the Epsilon Center in Vinewood. Make sure you have at least $50,000 and are still wearing your robes before you start the mission.
