whats the fastest yet cheapest way? i have an endoflame farm that takes care of the upkeep, i need 11,100,000 mana fast to finish my terra shatterer and then i wont need any more large mana quantities after that, is it worth setting up dandilifeions or similar when i dont need mana past this burst? im endgame in all mods except botania where i just beat the tier 2 gaia
