I'm gonna necro this 11 year old post to inquire opinions about a near similar question, but using a defending amulet of mighty fists with no enhancement bonus on it (as is legal per the text on amulet of mighty fists) and greater magic fang.
The enhancement bonus from greater magic fang doesn't have a conflict with failing to stack with an existing enhancement bonus on the amulet, because there isn't one. Would the defending special ability in this case be able to use the +X enhancement bonus from GMF to add to AC? Or would you still feel that the enhancement bonus isn't available to defending.
