Archeblade DOes cheat engine work?

when im in training mode i can use cheat engine to get infinite stamina but when i join matchmaking it seems like my bar freezez but i still run out.. is stamina and rp SERVER sided in ARCHEBLADE?

Yes, Archeblade does store most of the values such as hp, stamina, and xp on the server when you are not in training mode, whereas in training mode your game client is treated as the server. It is possible, however, that if you could host a server on your computer and have a friend join, that you could hack your exp and money by hooking cheat engine into the server process. (I have not looked into Archeblade servers, however this is a trick that works with quite a few games that allow you to host servers yourself, though in the interest of keeping this method alive I won't be naming the ones I know)
