How does the power attack bonus granted from these armbands (from complete adventurer I think) stack or multiply? That is, if you have an ability such as Leap Attack that multiplies power attack damage, would it multiply this bonus as well? For example, if my 20th level dwarf power attacks for 20 2-handed, I think it would normally be 20X2+2=42 points of extra damage. If I leap attack, I'm thinking it would multiply the previous total, becoming 84 points. It's not a big deal (only 2 points), but I thought I'd ask anyway.
