Is there a way to have a Catch for Recovery that instead of being something that prevents, being something that is required?

In other words, rather than say having a Catch of "fire" so your Recovery doesn't work on fire damage, you have a Recovery that requires something, such as blood or brains in order to work. Is this possible as the rules are written and if not, could this be a viable house rule option?

That Other Guy from RPG.net forums is doing up a bunch of mock RPG cover designs and did one for DF that I wanted to share with everyone here as I thought it was really excellent.




Here is the whole thread if you care to see the other minimalist cover mocks.

So here's what I have so far:

Manhattan - The city that NeverNever sleeps

Theme - Wake Up Time!
Threat - Red Court Power Vacuum
Theme/Threat -

Status Quo, Supernatural - Trying to catch our breath.
Status Quo, Mundane - We've seen everything.

Movers & Shakers -

Location - Central park    Face - Summer Court
Location - Harlem Face -
Location - Times Square Face -
Location - Woolworth Bldg Face - Red Court remnants
Location - NY Public Library Face - the Archive "Ivy"
Location - Chinatown Face - ghouls
Location - Wall Street    Face - House Malvora (WCV)
Location - St. Paul's Chapel Face - true believers, seeking new KotC
Location - Carnegie Hall Face - White Council


Would love to hear ideas on where to go from here. Sadly, my group is unresponsive when it comes to city creation, as they are used to the old ways, where coming up with the world and the NPCs is a GMs job, not there's. So, I turn to you for help.
