Honkai Star Rail 2.1 Boss Fight : Ten Stonehearts - Aventurine of Stratagem 

I did it with fire mc, blade, bronya and luocha. Fire mc and blade were the only ones who survived that fight, and mc was the only one with decent amount of health left while blade literally got down to 1 hp(ended up getting an achievement for it). I knew fire mc and blade arent compatible in team building, but blade had enough health to withstand hits with aoe attack and my fire mc has over 3000 def; I literally put them in the team to be canon fodder for the hits, and they ended up being the only survivors. Watching footage gives me flashbacks on how I was stuck on this fight for AGES!

I did this with MC Fire (e6), Clara (e1s1), Welt (e0s0), and March 7th (e6) just to stick the same characters in the trailblaze main quest

I beat this boss on my second attempt with Acheron, Welt, Bailu, and March. I had march sheiding Bailu any chance she got so that way bailu could have health and heal people. There was a lot of close calls but it worked at the end. Never faced a much stronger boss like this before.

phyiscal TB, bailu, clara and fu xuan, but my fu xuan always dies

What’s your Clara’s stats, just got her today and built her up but I’m curious how much I gotta invest to see 22k damage on those talent activations. Mine did like 5k😭

I used physical TB instead of serval. But thats how i cheesed this fight

At this point I need loucha, or I will be doom even Gallagher I built still can’t save all

Had me screaming for dear life brah

I wish I had chosen Clara. I don’t even really use Bronya at this point 😭

Fought him with Fire TB, Serval, Acheron and Bailu. Tricky at first during the second phase. I use Serval and Acheron's skill for the rolls; Bailu's for healing since I know losing is inevitable; and Trailblazer enhanced attack for the rolls with the ULT just in case. In between the next RNG I just attack him with basic attacks and Acheron's ULT. Battle lasted probably longer than it should be but it works

Did this with Hanya, Fu xuan, Ruan Mei and Sushang

May i ask for planar and relic do you use for Clara and gepard ?

can acheron,ruan mei,fire mc and bailu work? or do i need to change anyone?

I defeated him with Argenti, Acheron,Ruan Mei and Lynx

I could have beat this first try if I had bailu but my team is Kafka, sushang, Pela and Natasha

Does clara , acheron , gallagher , mc preservation work

what eq lvl is this

I fought this dude with LC-less Black Swan lmao. Barely won the fight
