Some answers to your previous post:
1.When you have a lot of gold on an elf and want to become a better spellcaster your priority for items should be: efficiency based spellcasting items, cheap max mana items, CP fodder, refill potions, expensive max mana items, even more CP.
2. Starting the bossfight at lvl 7 sounds like a waste. I usually do that on non-TT elves. The point of learning is that you can ding a lot, more than regular guys, so you can start the bossfight sooner without the worry you run out of popcorn but the boss is still alive. You could hold off popcorn munching in the belief that prestige dings benefit you more, but numerous lower level ones are better at bosskilling.
I think there a 3 major ways of playing TT. The dodgestep striker, the multiding caster and the dodging poisonous regenfighter who converts out asap after picking up the boons.
For the caster to get the most benefit out of TT you should piety farm a lot, pick up 2 points of learning before killing any popcorn, get a 3rd one midway and spend your gold on powerful spellcasting items (BM ring, CB, Dragon Soul etc.).
If you see a good spellcasting god it's probably worth converting into more than taking a 3rd point in learning.
If you haven't tried it already give an Elf Assassin of TT a try, explore a lot (but leave some blackspace in subs and obviously useless tiles) and start popcorn munching/boss battling at lvl 2-3.
When you're not playing an Assassin you should take into consideration that consuming lvl 9s would be a pain, so try removing them and only start the bossfight later.
Since you're not measuring TT to exploitive JJ, I can say the benefit over him is having more gold, a huge string of dings for ridiculous amounts of refills, and a different experience if you're looking for variety.
Btw peakaboo JJ is not just about having more boons, it's having them extremely fast as soon as lvl1 and 100 more piety to abuse your next god. And then possibly your 3rd one too.
I agree that JJ isn't weak without peakaboing, if you don't mind spamming glyphs it's a more powerful but less convenient MA.
