Portal Troubadour

• Your main job is doing portals, greens and stripping boons from the boss. Still, this build has big potential in terms dps, so make use of it!
• You can use Harmonious Harp to ignore the damage of Soo Won Swipe, Primordus Bite, to give your squad more space with the spread mechanic. Note that Harmonious Harp does not work for the kiteable red AoEs, but it does work on the bee AoEs in Purification 2.
• Each active instruments will give you a +4% stat increase due to Fortissimo, so make sure to cast your shatters as often as possible while above the following note thresholds:
• • Lively Lute with at least 1 note
  • Flustering Flute with at least 2 notes
  • Deafening Drum with at least 3 notes
  • Harmonious Harp with at least 3 notes (cancel the channel after about 1/3 of its cast bar - you will still get the effect of the instrument as well as the full duration of Distortion)
