Almost lost due to bad decisions at the start, had to pop the Yendor early to survive an early starvation issue.
But, since I had GG at level 1, I managed to snag a nice amount of Piety (30) just from the ding from level 1 to 5. You wouldn't otherwise get much level up piety from him since it always reset back to 3 piety gain every time you switch to another god and back to him.
Earthmother allowed me to get the mobile subdungeon 50 Piety package, which was a cool Dwarven Gauntlets plus 2 each of the 2 potions. I consider it the better deal in this map considering the 100 Piety package only gives 1 more set of 2 potions and 3 Scrolls of Compression (rather than the gauntlets).
Humility and buying the Orb of Zot and using it (Elite items prepped) meant I could catch up on lost XP from the early use of Yendor. In the end, still had to settle for 3rd highest XP (275 XP).
Ending with GG with all mobs cleared allowed me to rack up some insane level of piety (basically buying everything, well only 1 item left, was out of gold, and converting all items, glyphs and food). In the end I managed to get 26 beads and Enlightenment which was just enough for another level up. Had 500+ piety and topped the piety charts,

If the last god that I ended after enlightenment was EM, I could even get another 50 to 100 more piety from the remaining blood pools. But considering I could end up killing myself if the Barbed plant spawned on the boss blood pool (since I converted everything including Burndayraz), I consider myself better off ending with Taurog. [Now, thinking of it, it may not be that bad if I ended with EM since using clearance or even leaving through the entrance signpost are possible ways to end the run]
Still, not a "good" run considering I could have died if I had not prepped Yendor. Major kudos to those who completed it purist or went in with minimal preps (I saw Madder since he is always doing this topping the damage charts thingy with no or just 1 prep).
