After playing archmage cremation to 100, i wanted to push the damage as far as i could. This lead me to intensify stacking, which with enough stacks allows almost all of the projectiles to hit a single targe. The kill isn't perfect but its the best i could get with my limited attempts. I personally think intensify stacking is the way for bossing but i might be wrong.
