I don't have a lot of time for active play these days. Apart from weekends I don't even have the time for ascending. In the last few days however I've steered away from my usual habit of Conjuring Baked Goods whenever I have a moment, instead using Spontaneous Edifice. As everything was at 400 or more apart from Chancemakers, Prisms and Antimatter Condensers it meant that, over 3-4 days, I picked up an extra 40-50 of those high-value items. These in turn gave the predictable steady boost to CPS (for free) but nothing to write home about.
What I didn't factor in was the equivalent cost and time cost of these items. So when this morning I switched to Earth Shatterer aura, sold everything and finally ascended, my Prestige gain jumped from 371M to 1.2Bn. Adding in the 1.6Bn I already had meant a Prestige increase of 75% - all for 3-4 days' repeated casting of Spontaneous Edifice.
(I realise that some members are getting far greater increases via the Godzamok combos and fair play to those members, I just don't have the time for that. However, I think it's fair to note that once you reach a point in the game where it makes more sense to save the cookies than spend them, that a few days' Spontaneous Edifice can bring about immense increases in Prestige for no cost whatsoever. That is until everything hits 400 at which point there are no more gains to be had.)
