"Reversed linked", or "Inversely Proportionate"

[BlueBuddha]

How much should a limitation be worth that either:

1) Cannot be used with another power. I assume this would vary, depending on the power it's exclusive with, much in the way linked is. A constant power would place a greater limitation on a power it's not usable with, etc.

2) A power, in this case, a characteristic, that is reduced in Active Point value as another constant power increases in active point value. I know this can be handled with a multipower reserve, but I have a 10 and a 18 AP characteristic being lowered inversely proportionately by a 40 AP Constant Power. So far, I am going with a -1/2.

Whachoo think?

In the 4th Edition version of Fantasy Hero, there was a Limited Power application called "Lockout". It meant that no other spells (powers) could be maintained while this one was in use. The value on that was -1/2.

Based on that benchmark, I would assume that a Limitation, saying that the power could not be used when a single other power was on, could only be worth -1/4 at most (in the same way that any kind of limited range is only -1/4 because no range at all is only -1/2).
