Am I just not looking hard enough?

It seems like I've been to every collector and crafter in Cantha, but none of them have any Restoration Staves in stock, but they have one for every other attribute, for every other caster class.

Are they out of stock (I didn't know collectors/crafters could go out of stock)? Am I just looking in the wrong place?

I want to complete my little Rt's staff arsenal, and have something for when I need to play healer. It's starting to get frustrating.

I've seen Wands and Foci from Collectors and Weapon crafters.

IMO, the wand and foci they offer are better than using a staff. You get +2 more energy from the wand (+5e^50) and foci combo. Not to mention the extra +20% chance from the wand.

Do you happen to remember where?
