Arbiter of Ash

Why is this boss overlapping giant AOE that have single hit mechanics?
Why does he shoot a giant beam in the second phase that is larger than the save area?
Why does he cycle through moves so quickly if I lower him to half hp fast?
Why does he have more damage reduction when he's doing his opening montage?

The onlycounter-play here is just outright killing him without seeing his mechanics.

Screenshot is a slam right as a meteor finished. 0 counter-play opportunity.

How about you play better?

People do it all the time just fine.

Tell me how... lol. I've never seen a single video of anyone not just out damaging the mechanics.

If you are referring the second phase where he does the wave and spawns a circle zone as well, the strategy is to sit near where the circle that appears to spawn, but close to the Arbiter as well (since I am pretty sure he always spawn the circle near him), if you are perpendicular to his side (basically facing one of his arms) you won't get hit by the wave and have enough time to just dodge roll or literally walk to the circle to not get killed by the arena.

Other mechanics are a bit easier to do imho.
