Heal Herald on Extreme Dmg Golem with afk 1k Toughness Mes

Healing "Benchmark" with a corruption variant of quick heal herald.
1 Mil golem with 25 Vuln
Alac on myself.
Extreme pulsing damage.
My alt is there with 0 additional toughness just to port us both in and stand there for me to heal through the dmg.
My build has changed slightly since this run (optimizing stats, not using off-hand sword).

Unfortunately this log did not save properly, the corruption trait line causes issues with the boss death and combat end not lining up. Here is another log of a similar pull, but in this log I wasn't maintaining swiftness properly (spamming facet of darkness too quickly).
