So i finally decided to try LK25 hc, after i got a lucky glider through the wall into syndras room.
Took me 6 attemps to defeat him, /cast [(at)ice sphere] death coil - helped a ton. Done with a 483 weapon, so i had difficulties keeping up the required dps, had to soak defiles and i kept a shambler alive relatively long into phase 2. I also had 3 Frostmourne rooms and got him down to 10% a few seconds before enrage hit.
Next up Majordomo, who`s still a brickwall which i cant get below 30% right now.
So far...
