so i'm very confused. So i know that if i combine sharpness 3 with another sharpness 3 it will be sharpness 3. Or if i do sharpness 1 with sharpness 1 will be sharpness 2. So does it have to be 2 same books of the same level? Then how can some players get a lvl 5 book? 5 is a odd number, is there no way to combine books to get V? is the only way to get v by enchanting book with table? Does that also mean my diamond sword with sharpness 2 can't be combined up to sharpness 5? (so it can only be up to sharpness 4 now?)
