Clan Centurio and the Clan Hall
Side Quest

You can join Clan Centurio and enter the Clan Hall after you have completed the first Hunt in the game to defeat the Rogue Tomato. Speak to the Bangaa out front to gain access to the Clan Hall and then speak to Montblanc at the top of the stairs.

Attaining different ranks will allow you to purchase new items at the Clan Provisioner in the Muthru Bazaar in Rabanastre. The rankings are as follows:

Potions can only be purchased when you are on the Moppet rank and Hi-Potions can only be purchased when you are the Hedge Knight rank. For some reason, Bubble Belts cannot be purchased when you jump to the Paragon of Justice rank but reappear when you are a High Guardian or Higher. Aside from those three items, you can purchase everything listed in the ranks below the one that you currently hold.

Record Breaker

The Record Breaker Trophy is obtained once you have earned 500,000 Clan Points. You can check out how many Clan Points you have obtained by opening up the Clan Primer in the menu.
