I've been spending a ton of keys trying to get my time under 10 minutes. Earlier today I had a rift where I spawned the boss in just over 6 minutes with power waiting (plenty of time for an add boss) but I got bloodmaw and failed. A few keys later I got this one and got the illusionist out of power finally. Still nowhere near perfect - floor 1 was bad, plus I had to do the port-out to get back to power, but it's nice to finally get a PB after a ton of effort. Not that I'm going to let it stop me from attempting for sub-10. I have some gear issues but I still know I can do it.
As always, I do not use any overlays or bot in any way, so this clear is 100% legitimate.
