When submitting a bug report, please use the below template and thoroughly fill out the necessary information.

Time: 6/7/2016 11: 05 am CST
Frequency: Happened twice
World name: Malboro
Character name: Charlemagne Martell
Monster name: Nidhogg
Class/Level: Paladin lv60
Party or solo: Party
In-game time: 10:05 am
Area and coordinates: n/a


Steps:
1. The phase where after the adds are killed and Nidhogg forms several circles around the map and then creates rings for where he will blast; even if the entire party stacks in the center beneath the rings, he causes an instant wipe sometimes.

The mechanic was functioning normally (as in, party survived) up until the party wiped a bunch during the final phase, so I don't know if it is something that happens with the AI if the encounter runs too long or what.

I think Nidhogg was acting as if we hadn't killed the adds fast enough, but that was not true. We killed the adds before he said his speech and formed the rings.

I looked up videos to determine how the circles should be managed, and I saw various methods succeed. So I looked at other points in the videos to find another key factor, and I noticed that all the successful attempts happened when the adds were killed before the knockback move Nidhogg does. So I went back to this trial and tested my theory by paying attention to when the knockback move was used. After several runs of this trial, I had defeated the adds before the knockback enough times to conclude that this is the only factor in whether the wipe move is survived. I believe it has nothing to do with the circles or being in the center, as opposed to what many people believe.

In short, it's a DPS check. If I am wrong, you have every right to call me stupid. :p

The knockback move is the end of the DPS check ,this is true.

However, even if you kill all the adds before the knockback move (which is when he says his line of text) the party can still wipe, even if everyone stacks in the center.

There is something buggy about it.
