How tall are the walls generated by an Innate Attack with the Wall enhancement?

[awesomenessofme1]

For the life of me, I cannot find an answer to this question. I've looked in the Basic Set as well as Powers, and in both places they say the same thing, a 3 yd long and 1 yd thick wall for each yd of radius on Area Effect. I can't find anything about height.

[David Johnston2]

Reasonably it would be up to 3 yards high for each level.

Odd. I could have sworn it was 3 yards high as well...hmm. Most Area Effect spells have a height of 4 yards at most so I'd use that.

Assuming that an exception isn't noted (and seeing how I can't easily find otherwise in my books), I would assume the below remains true:

When applying modifiers, you occasionally need to know the range, area of effect, or duration of an advantage for which one or more of these quantities is not specified – for instance, when applying an enhancement that gives a range to an ability that normally has none. Assume that range is 100 yards, area is a circle 2 yards in radius (and 12’ high, should volume matter), and duration is 10 seconds, unless the advantage specifies otherwise. Exceptions will be noted.

^This is it.

Thank you!

Kromm cites B101 (12', or 4 yards) as the basis as well.

Magic varies a lot, though 12' shows up there, too.

If you wanted to make walls higher than 12 feet, could you just on your 2nd attack stack wall 2 on top of wall 1?

[Christopher R. Rice]

In my campaign I use Area Effect to increase the height. It's worked so far.

The +60% version of Wall lets you reshape the wall, so you could double the height by halving the length or thickness. GMs might let you stack physical walls since Walls are also Persistent. (Otherwise the base would disappear when you stop concentrating on it to do the next level; they're Innate Attacks at the core.) Magic forcefields might just float in mid-air anyway -- no need for a supporting base. Probably want to skip the engineering calculations and just go with GM rulings on the spot for whatever seems reasonable. You can't have a self-supporting stone wall that's five thousand feet high and one mil thick, even if the multiplication works out to the proper volume.
