This game has already been modded and 80% of the players using mod have already been banned. Some 7 ~ 30 Days, some already permanent. Do a bit of research on google and you'll find the mod.
Mod includes things such as
MVP MINI BOSS auto hunt (Game breaking)
MVP MINI BOSS auto target (Game breaking)
Removes cool down on certain teleportation item (Game breaking)
Warp from anywhere to any map
Open any shop from anywhere (even secret ones where you need to do certain things to open, you can just type in the command and instantly open it)
these are just some of the most notable mods there's a lot more...
Just be warned tho, you will be banned most likely, as people will report you with the slightest of suspicions, especially if you're using the mod to hunt MVPS.
