White Knight Chronicles

Binding in this game means collecting items and upgrading weapons and putting them together to make a new weapon. It's quite expensive if you try to buy all the items so you'll want to scavenge/harvest (collect from sparkling, glowing or otherwise emphasised spots) as much as possible, as well as relying on drops. Later on when binding you will need rarer items and will instead have to focus on killing specific enemies, or harvesting certain spots to get items. The Phibianacci's Diamond is the last trophy you should focus on as it's in direct conflict with Gold Coin Purse. You will want to focus only on the higher level items you need to to be effective in combat.
