after 20 attempts I managed to finally solo lei heng with leisault

I superbia'd his new crushbound past ego which gave a fat fucking bonus to clash power. The fight went on so long I could actually get it to 12 stacks.
I also had every passive going for his other egos so I managed to stack up to 10 protection every turn which made even lost clashes deal only 1 damage to meur on each hit. He also had so much extra power from crushbound+regret that with full overheat+prey active he could still outclash lei heng.

Also for the first time ever leisault having unbreakables was genuinely useful. I got mega unlucky and fumbled a clash leading to lei heng chain winning every clash for the turn. Somehow this didnt fucking matter because leisault dragged one of the invisible stagger bars out from 1hp and did well over 2k stagger damage through tremor that it put it just out of reach when I started losing clashes. But because Leisault's unbreakables trigger tremor burst he just forced the stagger on lei heng anyways through tremor and gave him the middle finger before ending the fight.
