I think the absence of slow means Earthmother is the optimal worship today. I tried to squeeze what I could from a mono-TT approach, but I don't think it would hold against what's doable with skilled Earthmother play. I don't think mono-TT is much better than a smart conversion into TT, you might lose a few XP during the early leveling, but it's a nightmare to pick up Piety to levels where your Learning starts to matter, especially since TT doesn't really give you much while you're going for higher-level kills (except for that GETINDARE of course which I duly abused...

).
Yesterday in the Gob run I was totally trippin' on how crazy strong the character was with all the +Damage items I found in store. I totally intended to use IMAWAL but I didn't want to convert anything as that would've levelled me up, which I didn't want. Of course each kill kept me close to the next level-up, so I never really converted that glyph, and never really picked up IMAWAL...

Anyway, fun run.
"Thinker", just without the "ache".
