If I understand you correctly, your charecter will not benifit from Break HP Limit untill the armour containing it is actually equipped (if you try take the armour off it warns you this will affect the charecters HP)

Although you have used most of the HP nodes, later in the game you can buy clear shperes to wipe out all the small HP nodes and replace them with +400HP nodes (remember the maximum HP you can have is 99,999).

To customise a weapon with Break HP Limit you need 30 Wings to Discovery, the only ways to get these are to Bribe a Malboro (Calm Lands/Monster Arena) for 675,000 Gil for 4. The special way to get 30 is to win the Chocobo race beneath Remiem Temple with three open trasure chests.

There are a few armours ready equipped with Break HP Limit but mostly only dropped by bosses or Dark Aeons (if you have the Pal Version). Check the post below "dark matter... and other things" fi you have the PAL version for an explination on how to get armour from Dark Yojimbo with Break HP attached.

As Bingo said you can get Armour with the "Break Hp Limit Attached" if you haven't got the Dark Aeons in your version theres only one as i know of, "Omega Weapon" at the Omega Ruins, Possible drops after you kill it, Weapon with a nice: Triple Overdrive attached, Armor with, Break HP Limit...

If you want some HP spheres through taking up a challenge, "Ironclad" at the Monster Arena, drops 1 or 2 for a overkill, and sometimes a rare Dark Matter, He's Unlocked by capturing 10 of each iron giant species..

They are, Iron Giant at the North part of Thunder Plains.. Gemini A, Inside Sin or at the Omega Ruins, armed with a sword, and Gemini B Inside Sin or Omega Ruins, armed with a club, Each Gemini counts as a seperate monster...

"Nemesis" in the Monster Arena, after you have caught 10 of each fiend in Spira, can drop an armor that has Break Hp Limit in it. He can also drop weapons with Break Damage Limit. He tends to drop it for the person that dealt the killing blow, as I have tons for Wakka.

Attack Reels ftw!!!

Also note that those two ways arent the only way to get Wings to Discovery, as Shinryu, also in the Monster Arena, drops 1 as a common drop and 2 for an overkill.

It really isnt worth bribing a Malboro for half a million gil just for 4.

still guys when I equip break HP Limit to auron will it count the HP spheres I've activated so far? pactically is he gonna go from 9,999 HP to 15,000 (for example) just by equipping the armour?or the nodes Iacivated count for nothing?

don't worry, they will be counted for.

EG. If Auron has a maximum of 12000 HP without the Break HP limit, his HP will be 9999. But if you equip the HP limit break, it will increase to 12000. Note: Say Auron's HP is 12000/12000 and you equip another armour that doesn't have HP Break than your Hp will tumble to 9999. You can heal yourself to gain the 12000HP if you reequip the HP break.

I did it with the race in Remiem Temple...Auron went from 9.999 HP to 21.600!!!!!
