Is this to be done before or after the Temple of the Ancients? I did it afterwards, and found it so easy it was boring ._.

I managed to kill Rapps within 5 hits (two of which were Barrets 'Big Shot' limit break), by using the weapons found in the Temple of the Ancients (Nail Bat, Work Glove and Barrets punching glove.. Cant remember what its called ). The ones that dont have any materia slots, but increase attack power greatly.

So is it meant to be done before or after Temple of the Ancients?
