Everything that allows your players the chance to defy logic or physics always allows for the possibility for them to make you want to punch them in the eye.

That said, I'm not against cleverness, or Gordian problem solving. I encourage it. But it's when they find an Achilles heal to something important because they used the bag of infinity to bring in something you hadn't counted on, and, spare randomly destroying it (because they never come up with this plan ahead of time, oh on, it's always, "OH WAIT! DON'T I HAVE A THERMONUCLEAR WEAPON IN MY BAG OF 'SUCK-IT, GM!'?") (wow that mix of internal/external punctuation was intense. stop and marvel at it for a moment)there will be little to be done about it when that moment occurs. And then my denouement is ruined. And then I drink until I start raving about story structure, and how badly I hate them all. And then the pointy objects come out.

Hence this little confab ahead of time. What would YOU do with a bag of holding in Dresdenverse, as a player?

I would think one of his banes might actually be fact and disbelief. Hence his need for a Knight, whose job would be more to protect Santa, who is mighty except for that one problem where you have to believe in him for him to be able to affect you.

Physical Immunity. That's pretty much Superman all day. You can drop a building on him and he doesn't just shake it off...his hair's barely out of place. I've never seen him get "hurt." Pushed back? Sure. Delayed? Alright. Knocked down? He's never actually injured, bruised, cut, broken boned, etc. There never seems to be any actual damage to heal. I mean there is the exception of the time he died, but that was the only time I've ever actually seen him hurt when other external factors (no yellow sun, kryptonite, etc) were in play.

Well initial poster who had the idea gave it a -2 and he had some increasing variants and the like, but the upshot remains the same. Being able to carry ridiculous amounts of stuff, or ridiculously sized stuff (my player wanted to have a tiny clutch that she could pull longs swords, axes, and the like out of, which I thought was hilarious), in an "invisible" bag that doesn't count weight the same. One could put arbitrary size/mass restrictions on it I suppose...

Someone brought up in the Custom Powers what was, essentially, this idea. One of my players wanted a power something like this. I am reticent. I fear that clever players can take such an infinitely useful item like this and turn mortal kind upon it's head with it. Or at least my game. For while it may work swell in the "magic is commonplace" DnD world, I'm not so certain it doesn't have unforseen, possibly game breaking uses in this world.

So let the wild rumpus begin. Can YOU think of game breaking uses for this? Do you think it's a fine idea and I'm just being paranoid (though I can't say you can ever overestimate a player's cleverness). Please discuss!

Yeah I'm just trying to vette that with you guys see what you think...

That's just the problem is I don't know what else would be a good catch for this. He's powered by "nature" and responsibillity. It's a burden Solomon picked up, and he impressed someone with his responsibillity for the town, and the dead. It's a silent agreement/bond formed between him and a force that I haven't really fully explained. It's not any of the known powers. It's really just with the "heart of the city" itself, with nature, not with any cognizant power. He did it because no one else would. Necrotic power is something that can hurt him (but that can hurt any one) and will, but I don't like that as a catch. No one has access to that and that'd be too hard to figure out.

Okay so my only real concern now is can "The Catch" for his recovery/toughness be his Feeding Dependency on being in the cemetery? What I've decided is he gets Supernatural R/T, and if he's outside using these causes feeding stress. If he takes feeding stress this down grades to Inhuman R or T, or both if high enough, then one cancels, then the other. Feeding failure is passing out from exhaustion.

Can that qualify as a Catch? If so I'd give it a +2 for being easy to access, you just have to get him outside of the cemetery, and a +1 for how "figureoutable" it is, since he IS the Caretaker and his power comes from the cemetery it wouldn't be that big a reach would it? Or is it more of a +0? And would he still get the +1 for the dependency?
