World record for bonus experience, total experience on non-Gaan Telet, and close to the theoretical maximum.
I almost rage quit when I accidentally killed that goblin but in the end I decided to pretend that it was my Persian flaw. Scummed for ENDISWAL and then killed the monsters in reverse order. Tikki Tooki was on the field. I was afraid to waste resources on him because this was hard enough to set up as it was, but in the end I decided to man up and convert to him. I'll never get such a perfect storm again. Took two hits of Learning right away and ended up getting a third midway through the popcorn phase. I ended the game at exactly 100 piety, so I took a fourth hit just for fun.
I don't know if Learning xp counts towards the bonus points on the victory screen, but ENDISWAL xp certainly does. I found Pan's Labyrinth, which was perfect for me. I didn't need health, but really needed mana. I even deliberately hunted down the Hellbois because as zero-xp monsters they are the ideal IMAWAL target. Each one I bricked saved me 4 experience.
Here I am looking around amazed that it worked. I was terrified of dying to the goblin itch so I took it very slowly.
Here I am right before departing. From here we can calculate the total xp I earned and see if the Learning bonus got counted or not.
EDIT: 391 total experience. 153 monster levels. Does anyone know the exact formula for bonus xp? After the change it was never documented.
EDIT AGAIN: Did some experiments, and Learning does get counted as bonus xp on the score screen. I'd still like to know how much of my xp was from Learning, how much was IMAWAL, and how much was natural. The only way to beat this would be with a Fighter and a similar perfect storm scenario, but I don't think that the Fighter has the leverage to do it.
