The upkeep isn't so bad, but that's mostly because I have no idea what the cost of divine charges on the GE is, just been using my stockpile of energy so I haven't really felt it on my pocket yet.
Degradable items do continue to degrade once augmented, right? There just seems to be no way of checking their degradation state once they've been augmented.
Afaik charge reduction bonuses are currently bugged so getting a particular tier of it actually increases the charge/h.
Lastly, anyone seen the mining accumulator yet? I have both tech trees unlocked but so far I only have access to the fishing and woodcutting ones, I don't have the blueprint for the mining one for some reason.
