Everything is possible, just maybe needs to ask for it
Its not possible for the same reason some of these mods make you desync from the server, Gold, Gems, VIP, Battlepasses,
General purchases made in some games ask for server side validation,
some features that i saw that werent in this apk which i was able to manipulate through cheat engine are.
(Coins available in the dice roll minigame, Soft currency using client side validation.)
(Health, GodMode, Is provided in the apk) "Fails in some minigames/Guildraids because they compare playerstats to server validation"
(Game Speed, Is provided in apk) "Works"
(Damage, Is provided in apk) "Fails in some minigames but client thinks it didnt fail, causing rewards to desync"
Best guess is to try and spoof a purchase request using Frida (Which most likely fails due to server side validation)
I am sorry for the long post but i hope this clears some stuff up, I'm new to the apk modding scene and am a .Net/X86 Assembly programmer myself so if my post has any misinformation in it, experienced modders please correct.
