Here u are guessing how... There is 3 types of effects that give a player an advantage. 1. Enchants 2. Potion Effects or any others that cannbe removed by driking milk. 3. There is something Called "Attributes". Basically everything has an Attribute, like wood crafted instead of 4 planks into 6. The main 4 I reconize is that Speed, Knock back resistance (Used for Clients for Anti Kb), Arrow range, Also Strength. Its very fun to mess around with. Aslo it could make a sword were it has no enchants but, It gives you 3000x Attack damage. Not saying this will happen due to the "Transfering Glitch" was patched and inorder to spawn these things in takes 300+ Characters in a command block. Why? Because they /give command has so many uses not even thought of. This is for people who want to get more in depth with minecraft. Im giving a free problem Called GCG. (Give Command Generator) if you find it make your own custom items and put the command and Effects in here! You can enchant anything up to 32767. Lets see how creative you guys get!
