hmm thats a good question what about both? it takes 1 pess to make 1 chaos but 2 normal ess to make 1 chaos... normal ess is 20e pure ess is 100e...doesnt seem too fair..if you did this either normal ess, and therefore elemental runes, would go up, or you'd have to make it like 5 normal ess for 1 chaos uh no then you could only make like 5 chaos per run? that would suck and the chaos alter is like a maze so it isnt that easy to get through..
