Between 2nd and 3rd is perhaps a bit tight (unless you drop a lot of powers), but once you get to 6+ SAsc's if you're invested in +25% AP, I can definitely see passing through the next SAsc quickly. Especially if you pick artifacts like high level IM & TW on your 1st SAsc that will help you clear Hex more efficiently, and/or use TW/IM/SAC/FC powers to clear through levels.
Kind of like this: - SASc - Clear/Skip to Hard Ursa, get Superpowers - Use all SLs you have to skip 10 levels - Play whatever levels you're good at (have intel on, etc) - Maybe target Hard Far Land, Hard Scand to get the bonus mobile buffs & 4th slot - Clear EH to be able to Asc later - As soon as you have another 5 SLs, SP SL to skip 10 levels, repeat until you're at Hex - Clear Hex 5,6,7 times (do you calcs, as many times as you need to be able to SAsc with either 2 or 3 Asc's, whatever you fancy/whatever is optimal, depends on your +25% bonus counts) - SAsc & repeat
The majority of your AP should come from Hex, and whatever other levels you like/are good at (HEH, HT, HC, etc), so it's a matter of how good you are at either clearing and/or skipping all other levels and getting back to those levels. If you're good at it & are putting lots of time into playing, you can SAsc again in <10 days. If not, strap in & take the slow route. (;
Not surprising, unless you really go at levels like HEH, HT, HC, 7yw, 30yw a few times each, then maybe 0 Ascensions works, but relying mostly on Hex requires (according to my calcs) about 12x 25% AP buffs + the 25% Adv buff to get it all done w/o Asc, where each Asc clears Hex 5 times.
I just tried the skip level superpower to get as far as possible into the new levels, hoping to reach hex earth, then got thoroughly humiliated… surely I must be missing something!
