Two Suggestions for Ghoul Feral Meter Management
I know there's Perk cards and a new 4-Star Legendary to help maintain your Feral meter as a Ghoul. But I feel there are two things that would be small to implement, and a great help:
Allow users to craft (or receive) more of "The Fix"; which can be done in a few options:
Via recipe with some hard-ish to obtain ingredients (it does reduce Feral by 75%) and make it craftable
Treat it like "Stings and Things" where it's a Daily quest from Parthenia who provides one or two upon completion
Allow Parthenia to sell it to you. Like all vendors, she has limited inventory (1 to 3) and it resets daily.
Introduce "Irradiated Bubblegum" variants
Humans have various Bubblegum items that slow hunger and thirst (not something Ghouls have to worry about). Make an Irradiated version of this for Ghouls that slows the Feral meter. Maybe extend the time to 10 minutes from 2 minutes.
Similar to the Perfect Bubblegum variant, which maxes Hunger and Thirst need meters and keeps them from declining for 60 minutes. An "Irradiated Perfect Bubblegum"; or "Glowing Bubblegum" could provide a Max Glow (or like 500 Rads) and halt the Feral Meter from decreasing for 60 minutes. Give it the same rarity as Perfect Bubblegum.
