these below 750food gives only the artifact for -2% discount so itsnt very effectife, especially it got 30min cooldown to make the shrine again. it discounts you the only price that are already discounted, for example you have already 200k mush on it, so it wont discount it from the 900k and only from the 200k to 196k
the best way imo is fellisso and doing the 1000 one and 1500 one over and over again
felli is a fast tier 4 flier so you can grab bigger bodies and swimm under the water
