A Ward Question

[Tedronai]

There is nothing that I'm aware of (either in the rules or the novels) that would prevent a given threshold from supporting multiple distinct wards.  In fact, such a strategy seems very similar to what Harry used to 'ward' the storage facility/safehouse.

There is some significant potential for abuse with regards to numerous weak highly permissive wards being used to support powerful landmines while devoting a single ward to creating the most potent conventional barrier possible.
GMs be warned.

Except possibly for the part stating "It must all be cast as one spell."  That seems to disallow multiple wards tied to the same threshold.  It may allow warding an interior room or circle in addition to a house ward.

Which book is this in?  Not ringing a bell at the moment.

I think I'd allow the circle but only one per structure/threshold otherwise.

Actually in the Warrior, Harry has a gun safe which seems to bear some sort of Ward on it as well, which does indeed suggest a Ward-within-a-Ward is possible

In Turn Coat, Harry had a storage facility with a Faraday cage to provide something resembling a weak Threshold.

The "LEGO" approach to Wards might be best replicated with a series of individually weak overall Wards which are stronger acting in concert

Was going by the game text rather than the fiction but I'm not sure either of these change that.  Both a safe and a faraday cage are standalone structures.  They're not (usually) part of the building containing them.  (I'd probably go with a circle for the safe unless it was a walk-in vault.)

Are you referring to Ghost Story?  If so, I'd model it as an aspect rather than separate wards.

I always pictured wards being able to be layered so to speak, but if not I could do it another way.  The house in need of wards is a beach style home in Hawaii.  It is completely encircled by a deck running around the whole house (not that it is that big of a house, it is actually quite small).

So I could use the house itself for one ward and then anchor the second onto the outside edge of the porch 'encircling 'the house.  A deck is a metaphorical boundary or 'threshold' from the yard, granted probably not a strong one, but one none the less.

The 'Faraday Cage' was a metaphor used to describe the effect of the wards Harry placed on the facility, not the structure the wards themselves were built upon.
The wards on that facility were explicitly described as being composed of numerous weak protection spells layered one upon another until the whole created the desired effect.

The quote from YS about being cast 'all as one spell' supports at best a tenuous conclusion against what I described; just as easily, perhaps more so, it could be read to require that any and all landmines attached to a particular ward must be cast as part of the same spell as that ward, and placing no restrictions whatsoever on whether other wards, with other landmines, can be supported on the same threshold.

That's the way I have been reading it myself.
