This achievement is awarded for defeating Rondo on floor 11 of the optional Mysterious Unison dungeon.

It is possible to get this achievement on your first play through but only by backtracking after defeating "Ruined Body" at the top of Double Reed Tower.

Once "Ruined Body" has been defeated he will drop the "Hero's Crest". Instead of going through the portal to the last boss backtrack and leave Double Reed Tower.

Head back to the Noise Dunes and head either East or West 3 times until you reach the Oasis.

Here you will find some large doors that can be opened by using the Hero's Crest (also unlocking the "Hero's Gate" achievement).

Once inside you will see an event that will explain your quest within this dungeon.

Work your way through the dungeon obtaining all 7 soul shards (I recommend using the maps found at You will also obtain the Party Level 6 achievement after defeating the first monster in this dungeon.

You will find Rondo guarding the teleport platform at the end of floor 11.

Defeat her to obtain the achievement.

Be warned: she is a very fast attacker and is difficult to guard against.
