Later on during bard gameplay, you are required to stand still a lot to optimize your DPS thanks to the Wanderer's Minuet. Unfortunately, the quest "The One That Got Away" has you mopve around a lot and if you do not, you suffer a lot of damage dealt by the NPCs attacking your character, even from non-Area of Effect attacks. Please consider easing the damage of the enemies, increasing the cure power of the NPCs allied with you, and/or give echo to players right away regardless of them failing the duty.
