As for the DB, it's nice, but it's hardly essential. Once certain zones got GoV, I took all my jobs to 57 (the sync limit in CN) over a month or so. DB craps out at 30, after which you just look like a noob for wearing it. It only takes a couple of hours in Gusgen to hit 30 these days.
Woah, what? I've been out of the game for a year, and they slashed Tab prices to less than one tenth of what they were?
I remember having to spend, what was that, like 100 tabs on Food Effects/Magic Buffs? Now they're _10_ tabs?
And 7... seven... Conquest Points for a Scroll of Reraise?
Book Reraise has always been 10 tabs. Nothing has changed. Your memory of tab prices is faulty. But in dungeon areas you can now get RR3 for 30 tabs, and it lasts two hours like all other book reraise.
The RR/Warp/Retrace scrolls, though, yes. It's the reason my HP is at the crystal in Port Jeuno. Use warp scroll, get another from NPC. Then if I'm going to WG, I take a shortcut through chocobo circuit which pops me out right by the WG warp NPC.
