Ambush and Assassinate - Simultaneous damage

suppose I have 5 arcanist brands up, not attached to anything, and my arcanist brand is linked to a spell that hits enemies

I walk up to an enemy and use brand recall, all my arcanist brands are recalled, and they all trigger at the same time and hit an enemy that is at full life

do they all benefit from ambush and assassinate's 100% more crit modifier since they hit the enemy on the same server tick?

I think no because I don't think the server tick matters, the server doesn't store updates then process them on a tick a tick is when we get/post an update to what happened.

So the first hit should knock the enemy off full life then the rest resolve differently. Some value snapshotting would have to occur for this to be different and I can't see why they would go for that though as it would get very messy if non similar attacks were simultaneous.

If attacks happen on the same frame for example they don't get collated together they still resolve separately.

This answer is based on my own conjecture on how the system works btw so I can't give this 100% certainty but just working through it in my head I can't see why it would work otherwise.

If it does would love to read a random Mark post explaining <3

yes, looks like mark already answered this

it's very old, but I guess nothing changed since then
