Flux Shape (Ex): By taking a -2 penalty to Strength for six hours, the creature gains the powerful build ability for one hour. By taking a -2 penalty to Dexterity for six hours, the creature gains the slight build ability for one hour. It may use either form, but switching adds to the penalty and only one build ability can be active at a time. This affects the weapons of Improvised Weaponry immediately.
Shouldn't the -2 penalty be switched (Dex for Powerful Build, Str for Slight build)?
