[TET Pit of Undying] Ascendra does not lose the DP buff on intended mechanics

Bug Name:

[TET Pit of Undying] Ascendra does not lose the DP buff on intended mechanics​

Bug Description:

There are few issues with this boss, though the most severe one is the DP buff, which is granted to Ascendra on 80% hp is not being actually removed (only visually).
The full scenario of the fight is expected to be following, according to retail version:

-On 80% hp Ascendra summons her pet "Kun" which is supposed to start his "rolling attack" animation towards your position. If Ascendra is knocked down + in the way of Kun animation, the DP buff is supposed to be removed and you continue the fight until next 20% hp is removed.​

How to reproduce/proof:

How it actually works on gamezbd:
1. Kun is summoned instantly together with Ascendra when the fight starts (he's glitched into the back wall)
2. On 80% Ascendra gains the abovementioned DP buff, and starts her "white animation" cycle when she can be bound/knocked down.
3. Upon Kun animation hitting Ascendra, the DP buff diseappears from the buff bar, however her actual DP does not change. This is the most serious issue, as there is no way to remove the buff properly and the fight becomes a pure dps check. Even with 310 ap it could take as long as 10 minutes to finally finish Ascendra.
4. There are no subsequent mechanics unlike the retail video (60/40/20% hp).
5. Kun becomes unresponsive and stands still when he's down to ~50% hp and stops his rolling animations.
6. Kun does not reset HP if you "fail" the mechanic as seen in the video.

Of all those, most are not so relevant if the #3 issue can be fixed. If it's too complicated to fix the mechanic, then DP buff should not be granted at all, as this boss does not pose any real challenge anyway.​

 

Checked it today, working mostly as intended, with neglegible quirks on the "Kun" bear side, but nothing that would prevent the mechanics from working. Possible to finish in 2-3 minutes now, thx a lot
