I learned a lot during this run and the only major mistake was not being aggressive enough to push it into a 10% enrage early so I had to sit through dives before I could kill it.
Id absolutely blows up the core while he's in dragon/godmight so I can definitely use SBAs off CD instead of holding them for enrage like how I usually do on my other kills.
Build is at the end of the video (Supp V+s are optional).
