Your goal should be to get ~1000 more SAscends and select 100 starting AP each time so that by the end you can just endlessly loop your superascends without even really playing
If I have any sac powers, I like to use them on War of the Worlds and Ursa Luna. I can then unlock battles and challenges after sacing Hardened Ursula Luna. No other hard till Hardened Far Land. Skip Reconquest 1065 (just started getting enough ap to have skip this early) After Europe 1066 AD upgrade to 2 skips Hardened Old Town x4 upgrade to 7 skips Hardened Rise and Fall of the Roman Empire x4 Buy Simultaneous Levels after 1st one. Hardened Scandinavia and the Nordic Countries x3 Hardened Copper Creek Castle Super
I keep a spreadsheet with my best sac times and non sac times so I can choose which levels to use sac on. When I build up 5 IM I do HEH
@Ivan: How much would instant hospital upgrades change your time per super ascension? The top 25 reward is kind of ridiculous and it changes strategy *dramatically*.
