When three characters are in the party, one of two Party Abilities is activated depending on the attack types represented by that party’s makeup. These two party abilities are as follows:
Rare Item Drop Rate Up
This ability activates when characters with each of the three attack types (Slash, Strike and Pierce) are represented. When this ability is active, enemies drop rare items more often, allowing you to gather rare materials for refining with greater ease.
This ability activates when there are two characters with the same attack type in the active party. This party ability allows parties which lack one of the three attack types to compensate for that weakness, in addition to dealing more damage against bosses and other enemies that have no weakness at all.
