Haven't uploaded any League Raid contents, because I didn't have much opportunity to play and upload content.
This build is not quite ideal, but still somewhat playable. Unfortunately I couldn't one shot him.
Tier 3 hinders your swapping in/out.
Tier 4 hinders your casting of specials, and have reduced DOT damage due to his immunity.
Perhaps the build would work if I used Raven instead of CTF as support.
The hazards which used to appear in Phase 3 still remain missing.
I am a FREE TO PLAY player, so I generally work with whatever is given free.
