Get a full set of topaz HQ accessories. Parry is amazing on warrior (it adds 16 automatically on each piece) and you meld str instead of vit materia (absurdly cheaper). The skill speed is alright, but your last on priority for getting TP in fights so running out early doesn't do you any favors. The main reason I love the topaz is because of the big parry boost, as it's your only defense (you can't block) and they have made the final content in such a way you will be tanking at some point on something every fight.
