Ghoulish (Fallout 4)

Ghoulish is a perk in Fallout 4.

Description
This perk functions by healing a multiplier of any rad poisoning you receive. At rank 1, 50% of rad poison received is healed as health; at rank 2, 100%; and at rank 3, 150%. 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 you have, the less rad poisoning you receive, which reduces how much health you restore.
