You can start this fight falling-down drunk. I just did this. I should also mention it cost the adventure. The next day I fought it sober, but at 0 adventures left.
Scaling appears to be capped to 11000 (before ML). For damage reduction sample: I was still doing 2.5k dmg with normal raindoh'd saucegeyser, 4.2k when critial (fluffy bunnies take ~613k from those same crits). --xKiv (talk) 01:58, 6 September 2017 (UTC)
I'm level 23, maximized my spell gear and easily took down the genie.
