  1. Boss regenerates life!
    As already mentioned, if you can’t kill this boss within a minute or so, the small room is pretty fast full of turrets and degenerating voids.
    ps: there is only one portal to the boss room, but you can use it repeatedly.

  2. This boss just wipe the floor with me , 6.5k life 60% phys reduction , 76% lightning res
    + Fortify
    but the amount of turrets is insane , after 1 minute the was barely some room to move and not take damge

  3. Just killed it for the first time, didn’t drop a Synthesis unique. It was only a level 74 area, so that could be a factor.
    A few things worth mentioning that the guide doesn’t bring up: The boss will spawn adds either after a duration, or once he gets low, but until then, you do not get a chance to refill your flasks. The pylons have a fairly long duration, but they spawn in an inert state and don’t deal damage immediately unless they’re already active, so if you’re going for the league challenge where you aren’t allowed to take pylon damage, you can walk past them while they’re closed without any issue. From what I could tell, the projectile spin attack’s projectiles do not pierce, so if you want to ensure your safety, use a minion skill like summon skeletons to block them.
