Adamantortoise Help?

Disclaimer: I don't know the difference between Adamantoise and Adamantortoise in terms of their attack pattern. For the Adamantoise at least, he does about six stomps before Quake/Roar; at the stats you seem to have (plus Highwind), that is more than enough time to take the 'tortoise down before seeing those uber-moves.

I just know tortoise has like 1.5mil less stats, apparently weaker phys, but stronger mag

You do not need Shellra since the stomps are physical, so go with only Protectra to save time. In case you weren't aware, merely being in the Tortoise (the Sen/Sen/Sen) paradigm will reduce your damage by a significant amount, so you should be switching to Tortoise for each stomp. This way you don't need Snow to be a perpetual Sen. Also, equipping everyone with a maxed Gaian Ring will offer 40% resistance to the stomps since they are earth-based, so I suggest maxing those out and equipping them.

The protectra only might help, but vanille dies/almost dies in one quake without shellra (Maybe those earth res might help>=/
So I should go to tortoise like every five turns (or however fast stomp comes)?
I know that helps with atb advantage stuff...so much worrying XD
So just increase earth resistance...can i buy earth rings? I have a clay ring and a slitstone ring, thats it

If it's taking you two Highwinds to take down a leg with Bravera and Deprotect, something might be going wrong. (I'm not so experienced with Highwind so I can't say for sure.) You should be boosting Fang's Strength to ludicrously high levels, though. The two good choices for weapons for Fang for Highwind purposes are the Dragoon Lance and the Taming Pole; when either are fully maxed out to Kain's Lance * they give Fang over a 900 Strength boost. The Dragoon Lance hinders your magic but the Taming Pole has Stagger Lock; however, Stagger Lock is generally not an exceptionally bad thing for one party member to have (you'll run into problems if two or all three have them, though). I'd look into investing in upgrading one of those to at least maxed tier 2.

Fang's only got a max partison, but okay, i think ill go with the taming pole. The helpful part about that is i DONT want fang staggering the legs while vanille is still needed for healing. But i think i sold mine...theyre expensive

In addition, Warrior's Wristbands/Power Gloves/Kaiser Knuckles are good Strength accessories to throw on Fang. With three accessory slots, ideally you should have Gaian Ring */Strength accessory/Strength accessory as your three equips on Fang; the others need at least a Gaian Ring *.

Okay, strength!

If you're doing all that and you're still having trouble one-shotting a leg, maybe post your equips and stats so we can have a better picture of what's going on. Also, this guide might help: http://www.gamefaqs.com/ps3/928790-final-fantasy-xiii/faqs/60236

Equips and stats, okay ill do that eventually...i cant use my ps3 right now

As for Mah'habara, that Juggernaut does not respawn. At this point, however, you're better off grinding for gil instead of focusing on grinding; you pretty much will always need gil but you won't always need CP. (Of course, since you are in post-game, once you are able to kill 'toises consistently, you won't need to worry about any other farming method.)

So any good places to farm? I'm just in desperate need for some HP, so I was thinking about gathering around 600k for everyone and filling in some of those 60k nodes, maybe getting a level 5

You should have gotten a Clay Ring on the Steppe and another in Taejin's Tower. Try checking the Item Location Guide and see if you can find the one you missed (unless you sold one . . .). Also, you can get an Earth Charm on the Steppe. Max and dismantle this for another Clay Ring.

Did you beat Mission 55 for the Growth Egg? You should do this before you consider any farming.

You can't buy any form of a single element resistance accessory or its corresponding charm.

General's Belts are nowhere near as potent as Gaian Rings, but they serve roughly the same purpose. You should be able to use the method shown in this video once Fang has ~16,000 HP (16,000 HP and 25% damage resistance is roughly equal to 13,000 HP and 40% damage resistance): http://youtu.be/sciEeeVx-G0

Alternately, you could restart the game and make sure to hold onto the limited items this time. Re-doing the stuff you've done so far will go much faster the second time, and you'll sharpen your playing skills.

You should be killing the leg essentially immediately after it is staggered (you might have to chain up a bit here). Just wait to rebuff after Highwind.

You definitely need to buff once the Adamantortoise falls down. It will stay down for one minute. Syn/Sab/Sab is better than Sab/Sab/Sab since you can't waste time in Syn/Med/Med after it falls.

Try the Upgrade Guide for making accessories. Generally, you want to buy the components. You can use whatever organic components you've got for the experience multiplier. If you can't find copies of the necessary accessories, use the Item Location Guide. The Healer's Staff is terrible. Definitely use the Belladonna Wand or its upgrades.
