Regarding LK 25 HC
When you enter the 1st transition at 70%, make sure you can top yourself before it ends, cause LK will cast Infest around 7-10 sec after starting P2, meaning you will have to be above 90% HP, otherwise it'll just keep ticking until you die. Since it's no longer a DPS check for us, the easiest thing to do is just to chill outside of Remorseless Winter and dps a bit on the Raging Spirits. Personally I keep 1x Raging Spirit up and Distracting Shot it, followed by a Feign Death (to stay as a tank), some just does it with LK.
Btw, I was clearing up to Ultraxion in DS 10 the other day, hoping to get the mount from Ultraxion. Question is:
Has anyone figured out how to solo Ultraxion? I kept dying to his Arcane Dmg pulses, hits me for 190k. I was wondering if I had to swap to MM for Chimeara Shot heal. Any help would be super!
