You have 3 riptide charge (6 sec cd) each generating 2 charges of Tidal Waves. At this point this isn’t a modifier anymore, more like a permanent buff on your Healing Surge.
Modifiers for BIG Healing Surge are Lava Burst, Healing Rain (if talented Deluge) and Unleash Life.
You can add Ancestral Swiftness 4 part set bonus and on use trinket for completing the party.
As a not-even-average player, I still don’t understand why sometimes my Riptide crits for 500k and sometimes for 50% of the tank’s hp. Or how placing a Healing Stream totem barely does anything, but somehow placing a 2nd Healing Stream totem and no other ability the entire party goes from 40% to 100%.
Yes but lina started trying to make a fool of me by looking at crit values in logs. But healing surge crits way more than that it not crits. And tidal waves are a modifier, of course. It is just that we with Farseer get way more of those.
