God Catching Alchemy Meister:Quest 108

Wailing Legion
Just like in Quest 106 Lyphia and Evelyn will temporary join your party, so the same problems with high level enemies can occur. Also in this Battle will be various Envoy enemies, those can only be killed if the final blow is one of Lyphia & Evelyns combo attacks. If its any other attack the Envoy will simply respawn with full health.

After Lyphia & Evelyn finished the four minor Envoy enemies of, the sealed of room with the final Envoy will open. Despite it's a tougher version than the other four, it lacks the respawn ability that the minor Envoys had.
