Channeled raid heal on all allies within 40 yards over a 6-second channel. With the Flourish talent, every active HoT on the group is extended by 2 seconds per second channelled, roughly 12 seconds across the full channel.

Strongest when fired into a pre-built HoT carpet. Lay down Rejuvenation and Wild Growth beforehand so the extension and Mastery stacking carry maximum value.

Best fired around 7-8 seconds after Convoke the Spirits, once the wide HoT carpet it spreads has fully landed for Tranquility's passive to then extend. When timers don't line up that's fine, fire it as a standalone ramp tool on the next damage window.

Less important to pair with Incarnation: Tree of Life, since the form doesn't actively widen HoT coverage the way Convoke does.

Avoid assigning Tranquility into forced-movement phases, it is a channel, so the druid needs to plant their feet for the full duration to get the value out of it.
