More as a throwback to the alpha version of the system than anything else, it had previously been established that only certain classes (specifically, alchemist, sorcerer, warlock, and wizard) could botch during action development. After discussing it, we quickly realized that this lacked parity without any good justification. Thus, any character, regardless of class, can now botch while attempting to develop an action. The and system settings have already been updated to reflect the change.
