I undid your recent edits to hostile mob pages, and would like to explain why to help you with your future edits.
Unfortunately, most of the edits contained grammar errors, and the "Ways to kill" sections that you added were located after the trivia section, which is incorrect formatting as the Trivia section is always the last section. Also, many of the pages already have a combat section, which details how best to fight the mob.
Please take the time to ensure that what you add to pages is not already present in another section, and please make sure that the edits contain no grammar errors. It may take longer to proof read, but it ensures that your edits are always good quality ;)
