Hello all. This is the user named Legendary. It is a cliche name but vague enough to provide assistance on this reference site. This page is dedicated towards the experience and tips of a certain player who is still playing Phantasy Star Portable 2. Hopefully this page will provide some help and useful information for those that are also seeking to sate the OCD of completion of their game.
Tips of the Trade
All collectable items such as weapon badges, spellstones, and photon parts can reach to the maximum of 999. To avoid this, there are some ways to attain more mesetas out of such parts. After beating hard mode, you can use your hard earn collectables to purchase weapon/armor sets and modules to yield the maximum profits. The Trade Missions provided without DLC are used for this instance.
