Nidhogg Glitch?

This post is just to find out if what we experienced yesterday with Nidhogg is a glitch or a new and normal mechanic of this king. Basically a nin, drk, whm, and thf (me) easily worked him down to 40%. Nin took a couple hits and hate bounced to me just as I went behind the NM to sneak attack. You all can guess how that turned out. Spike flail wipe. The drk dropped party and used the auto-RR from the twilight gear to reraise and maintain DoTs until the rest of us were fully rested. Nidhogg had regen'd 10% or 20% before/between DoTs so the rage timer had reset. When we were ready, we let it go back to its spawn point and the nin claimed it. After this however, Nidhogg would track whoever had hate, meaning it was no longer possible for everyone to stand on its front legs. After a long and very fun fight we eventually had to swallow our pride and call it off. I'm wondering if this is a glitch/bug or a new mechanic triggered after a wipe intended to make this NM more difficult. Did this happen with Nidhogg before the update? I'd never actually fought it before but I know how wyrms should behave and he wasn't following the rules :D Thanks in advance for your responses.

would guess its a glitch, had the same thing happen on a couple popped yilbegans, would track tank makin it impossible to fight with constant doom timers

Fafhogg tip #1: always stand on feet
Fafhogg tip #2: never move from feet
Fafhogg tip #3: win

i don't know about Nidhogg, but this happens alot to Dragua when you make it walk on unstable ground, it get fixed after kitting on stable ground from my experience, might be because the DRK kited it the same way on unstable ground

Unless you're solo.

I know. I was hesitant on every SA attempt. I was told to try to get max TH on it and no one complained after the first SA. But I do believe we would have easily won had I not tried to poke the wyrm in the bum.

i lol'd pretty good lol.

SA = wha? come on you all know this who ever has experienced with kings... yes your right it is spike flail noone should try to SA faf/nidhogg
