As requested, I have done a speedrun of the Peak of Vindagnyr domain after Zhongli's buffs. Domain was cleared using only Geo characters. The two Pyro characters were only used to remove Abyss Mage shield and activate elemental synergy.
Shields are really useful in speedrunning this domain as it allows you to negate damage and knockback from the Lawachurl which would otherwise stagger and also kill you.
My previous run during 1.2 was 1min 20s, so this run is approximately 33% faster. Zhongli's buffs not only increase his melee damage but also lets me put up both pillars without needing to wait another cooldown cycle after applying his shield. This gives more resonance damage per tick and more energy particles overall, letting me spam his Q and Albedo's Q faster.
C6 Zhongli Level 90
R1 Vortex Vanquisher Level 90
Talents: 8/12/11
4pc Retracing Bolide (Crit%/Phys Dmg%/HP%)
C1 Albedo Level 80
R5 Festering Desire Level 90
Talents: 6/6/6
2pc Noblesse + 2pc Archaic Petra (Crit%/Geo Dmg%/Def%)
My characters' artifacts are scuffed so I could definitely go faster if I had better stats, but farming for better artifacts would take a long time and I'm content with their current performance.
