Scholar Bug in P2S - Instant Kill of Shielded Party Member

Frequency: At will
Character name: Forgotten Nerd
Monster name: Hippokampos
Class/Level: 90 Scholar
Party or solo: Party
Area and coordinates: P2S
Steps:
1. Fight him until he does "Channeling Flow"
2. Crit Adlo any party member
3. They die instantly upon the arrows going off

This works on all Channeling Flow mechanics in this fight.

Example(The Bard consented to being my test subject after I died 8 pulls in a row deploying off of myself).

Details: This bug appears to be related to the Catalyst buff that crit aldoquiums give. When I right click off the Catalyst buff, I do not get 1 shot by Channeling Flow.

I have also confirmed a 2nd iteration of this bug occuring specifically with Channeling Flow occuring at "8:15" of the fight beyond those mentioned above.

Frequency: At will
Character name: Avalen Koma
Monster name: Hippokampos
Class/Level: 90 Scholar
Party or solo: Party
Area and coordinates: P2S

Steps:
1. Fight him until he does the "Channeling Flow" that lands around 8:15 mins of the fight.
2. Use Recitation + Adloquium on self, then cast Deployment Tactics on self (aka adlo spread)
3. Both sets of 2 players, when their Channeling Arrows Resolve, they will be pulled together and all 4 will die instantly after taking damage twice from "Crash". Players received a Damage Down immediately, then receive Crash (1) "0" Damage, Crash (2) "XXXXX" damage (Killing blow)

From testing, this particular version of the issue is only present during this specific "Channeling Flow" occuring at 8:15

I have done it during second and third Channeling Flows as well. Single target shield and only 1 guy dies.
