This includes x-ray Texturepacks and bots such as baritone. Litematica, Badlion and Optifine are allowed. If you are caught with a hacked client you will be banned whether you were cheating or not.
Abusing bugs before/instead of reporting them will not end well for you. If you find a bug, item duplication method or anything suspicious it must be reported immediately.
If you choose to break any of these rules, you may be permanently banned from Newwind.
When figuring out whether something not mentioned in the rules is allowed its best to use common sense.
The rules above can change depending on a number of factors, so players are recommended to look at the rules page regularly.
