This seed is responsible for granting the party a special class of items known as "proof items" (e.g., Bottle of Blood for Charlotte's Dark-Dark class, Evil Shaman). These items allow the party to go beyond their first class. There is a catch to this; if the player wants to evolve the party further, the party must also be at Level 38 with the proof item in hand. ??? Seeds must be planted at an Inn, and the proof items that are received from the planting depends on the characters in the party, e.g., a Charlotte-Kevin-Angela party would give any of the four bottles, wolf souls, or books. These proof items can also be used in battle for secondary effects.
