I'm having trouble figuring out how to resolve the passive text on Pyromancer's Cache. Obviously when it comes into play you attach it to a location you control and kneel it, but what happens after the standing phase? Do you have to re-kneel that location to fullfill the passive effect? Can you then attach it to a different location?

For some reason I am feeling really stupid right now because i've never seen a passive kneel effect before and I can't wrap my head around it.

Remember that a passive effect must have a point of initiation. In short, there has to be a point of reference for WHEN you kneel the location in order for the kneeling to happen. Without it, there is no activation for the kneeling effect. Here, the "when" comes at the time the attachment is played. But without a specific instruction for when to activate the text again, you do not get to assume one or make one up. So if the location stands, there is nothing in the text that allows it to activate again, or to continually be kneeling the location the way a continuous effect would.

You could argue that if the attachment's text were blanked, it would activate and kneel the location again when the text came back, but blanking the text on Cache is going to discard it (since there is no text allowing it to stay on a location, either), the possibility is moot.

Another question on this one

If my opponent steals the location with cache attached, is it discarded as it is no more attached on a location I do control ?

I thought the restriction only apply at the time it was attached, but Elooooooooi seems to think the opposite.

This one can be answered right from the FAQ:

"Any attachment that has a restriction (such as "Lord or Lady only" or "attach to an opponent's character") is immediately discarded from play at any time that restriction is not met, regardless of immunity. Such restrictions are constant effects, and the attachment should be immediately discarded any time a restriction is not met including during setup."

I find the FAQ entry "Unless specifically stated otherwise on the card, attachments always attach to a character." very interesting. I've read through dozens and dozens of attachments so far and each of them so far imply what they attach to or not.

The idea that blanking an attachment will cause them to be discarded from play if they are attached to anything other than a character(ignoring character "No attachments except X.") is a curious use of blanking cards.

I find it odd that such a FAQ entry exists and that it's not something added to the rulebook. Then again, I suppose that there are plenty of specific rules in the FAQ... just this is specific to a key mechanic of the game with how attachments are used.
