Apologize if this is already common knowledge & will delete if necessary, but I thought I'd put it out here.

With the multitude of Terra friends out there, now is a good time to brute force Asura 2* with her evoke damage. Doesn't even need her LB, just chain her CW evoke damage (doesn't matter if it's just lv1) with another CW chainer (mine is GLSakura, but anyone else is fine).

The rest of the team technically doesn't matter, but you need to survive Asura's "Infinite Cosmos" on T2 (since she locks HP at 20%), so you will need a breaker on T1 (80% ideally). Especially since many of the Terras out there right now are built for nuking and not survival, I would also suggest double cast her CW the 75% self mitigation on her T1. You can put gut on your other chainer/units to survive it, but not necessary since using Terra's evoke chain by itself T2 is enough to kill the boss.

So yeah, turn rotation is basically--

T1: shift & dual cast evoke chain self 75% mitigation (chain with a CW chainer preferably, especially if the Terra friend isn't super strong)
T2: tricast her chain & Asura dies

This probably would apply to many other trials with mitigation shield (especially if using her LB), but since it's half energy on world revisit quests, I just thought to write it out here for Asura.

Cheers!

Edit: Some people have mentioned that other units can do this too, and I'd most likely agree (didn't test it myself but I think it should be right); I'm just mentioning Terra here because you are likely seeing many Terra friends, and she can most likely carry the trial in 2T (assuming you have a breaker). Again, this is not meant to be a "guide", just a quick tip to get your easy lapis (or esper, if you skipped it). Sorry if I wasn't clear.

Edit2: Apparently I'm dumb, you don't need to clear Asura 2* like the other world revisit quests, only the Asura palace. Thanks to u/dukasmc for the info. https://exvius.gamepedia.com/World_Revisit_Quests#Part_11
