There is several mistakes in your commands, such:
missing variable name that will set the value %%a to

missing % in %exp, and in set /a you shouldn't use the % in variable names, just the names.


I suggest you drew the logic of your game in a paper then start coding, and use functions instead of "Goto" commands, that will make you skip commands and confuse you and any one read the code.

Example, Attack function, should take hp, power and weapon, then any attack will have two or three possibilities, win, loose draw, and in these three possibilities the result will be change in the hp and other variable that you set at the start of the game so you won't loose track of the game and avoid confusion. and the data will always be accessible in the memory and always updated every time a function use them.
