Temporal chains affects Arbiter of Ash sword beam + bomb mechanic timing

Case 1: Temporal Chains

The Arbiter of Ash sword beam + bomb attack (occurs in the second phase of the fight) seems to have impossible-to-dodge timing when the boss is affected by temporal chains, causing the damage to overlap:

As you can see above, the bomb explosion seems to overlap with the beam in the same frame.

Case 2: Normal fight

The delay between the beam and bomb explosion seems to be at least 200 ms longer when temporal chains isn't applied to the boss. This means that after the beam animation ends there is a lot of time to walk into the circle.

Just wanted to second this. I had the exact same issue with an arbiter of ash run that I did as well where TC was active. The explosion timing was in the middle of the beam so there was no safe space.
