Ghoulish (Fallout 4)

Ghoulish is a perk in Fallout 4 and Fallout 76.

Fallout 4
This perk functions by healing a multiplier of any rad poisoning received. At rank 1, 50% of rad poison received is healed as health; at rank 2, 100%; at rank 3, 150%; and at rank 4, the radiation level will reduce slowly. This does not provide a constant regeneration effect based on current radiation poisoning (as the similarly-worded Fallout: New Vegas perk Rad Child did).

This has the ramification that this perk has a negative synergy with rad resistance. The more rad resistance one has, the less rad poisoning received, which reduces how much health is restored.
