Just finished running 939 explorer reports for Einhar missions. Started with 70, ended with 23 missions.
> Out of those ran around 8 untainted paradise, more came up but I was retarded enough not to notice it was a free reroll until I had skipped like 2
> I was only running einhar missions and untainted paradise otherwise. A single time both came up from a report and I did the mission.

I don't have the total tally of beasts because at some point I sold around ~18 divs in beasts to fund a 250% widowhail and some other minor upgrades. In the end I have:
> 23 vivid vultures
> 11 vivid watchers
> 8 wild bristle matrons
> 18 wild hellion alphas
> + some divs in smaller beasts. Of note is 30 wild brambleblacks which would add another 3.5 div to the total but I will keep them for myself.

That would put the chance for Untainted Paradise to appear at around 1% and around 4% for an Einhar mission.

> Why? Are you retarded?
Yes. Where do you think you are?
> Was it worth it?
I could make 10x profit running alch and go T16s
> Is it as miserable as it sounds?
It's worse.

Minus the reports it's around ~48divs in total. In the end it averages to ~1.3 divs per beast mission so the expected value is alright.
