Advanced Scale

[lnodiv]

Size and number of subjects is a separate Scale category from Area of Effect. With a -4 penalty and a reach for Advanced Scale, you can affect up to 20 subjects of Size up to15, or everything in a large warehouse or supermarket regardless of number and size.

Keep in mind that if he's trying to modify the entire apartment building itself, as opposed to applying an effect to everyone within it, then the Size would be an issue.

I think.
