Great idea for a new story

Just like many new authors, there is a time at the start where they will write a story at the beginning just o stop because of a new idea and start working on that. Well, I just came up with a new premise I desperately want to try out.I am not stopping this story but this story maybe on hold in the future. I am stubborn so I will return to this story and continue on as I do have plans I want to enact in this tale. The point is, I need ideas of random item, they can be funny, catastrophic,chaotic, amazing, or downright horrible.you can also write out skills with the same limitations. That funnier the better. Although I said catastrophic,I really mean in potential. I don't want anything world ending. The new story will be set in the Harry Potter world I think. Please give me your ideas in the comment section of this auxiliary chapter.please have fun with it. I want at least 20 unique items and 10 unique skills before I start this up.
