Has anyone defeat Diablo at Torment $player 10? Or even after 1 hour?
What's the max level of Diablo you killed?

You can drop 1000 mana on the ground, and pick it up at any time you want.

Today I found Heartseeker in Nightmare, level 16. My sorcerer is at level 35, while I set difficulty to $player 6, and killed a mini-boss, it dropped Heartseeker.
I was surprised, original I plan to get it at Torment.
