Heal Troubadour

Raconteur is the build. It turns all three Tales — Tale of the Second Scion, Tale of the Honorable Rogue, Tale of the August Queen — into heals with Protection attached, which is why the utility bar looks the way it does.

Life of the Party puts boons on everyone Lively Lute and Crescendo touch, and Altered Chord makes Crescendo hit harder by letting your last-played instrument colour it, then refunds part of its recharge whenever you play an instrument that ate a note. In Chaos, Chaotic Transference pays out when you pick up a chaos aura — Tale of the August Queen is your source for one. The reliable cleanse is not a Chaos or Troubadour trait at all: it is Mender's Purity, which fires a Lesser Power Cleanse every time you use a healing skill.

Giver's and Minstrel's with Water — healing power plus boon duration, which is what the Tales and Life of the Party both scale on.

Transference is the only piece here that raises outgoing healing (10% to other allies), so it sits on both sets. Flock keys off the heal skill: press Tale of the Second Scion and it heals you and nearby allies again, converting the overflow to barrier — and that same press also fires Mender's Purity and Metaphysical Rejuvenation. One button, four effects.

Frenzy and Life fill the remaining slots off kills.

Ally Stability here is one skill, Mantra of Concentration, and nothing else — no trait, no weapon skill on Rifle, Sword or Shield gives it.

So if the fight is a stability war, Chronomancer brings the same mantra plus Well of Precognition, Time Warp and the Quickness off Seize the Moment. Troubadour is what you bring when the squad is dying, not when it is being pinned.
