Heavenly Father is a Joseph: Collapse DLC trophy for unlocking all five of Joseph's traits at the Mirror. The traits are big passive upgrades for your runs, and only 0.6% of Steam players have the full set.
1. Play Joseph: Collapse. 2. Return to the Mirror between runs. 3. Unlock a trait whenever you can. 4. Keep going until all five are open. The trophy pops on the last one.
Go for the traits that keep you alive first, so each run lasts longer and earns more. The traits for Vaas and Pagan in their DLCs do not count here.
