Regarding the accessories:

- Both the Fending and Slaying rings have the same secondary stats. If you're feeling frugal, do the ones that will be cheaper to meld. For example, my server always has Vitality Materia more expensive than Strength Materia because Tanks have a huge allergy to the word "Fending".
- If you're looking to max Accuracy, you'll want the Slaying Neck with the Fending Earrings and Bracelet. Coincidentally, this will also give you Crit on every accessory slot if you're looking for that too.
