it does not prevent the stage verification aka the server side security
it only allows u to read memory for the game
the ACE basically makes it so that 3rd party app cant read memory
sanity checks are still a pain
pc version has even more good security than mobile
mobile is easier a bit but because of sanity checks
both are hard
but tbh unlike genshin this game way easy so i dont mind if there is no mod
game security pretty good
even if u have god mode or insta kill or inf energy
game wont let u finish the battle
it will tell u to redo the battle
they probably have AntiCheatExpert
at least in pc version
good luck with mobile
