Jump Ultimate Stars/Items and status

There are all kinds of items and effects available in Jump Ultimate Stars. BE sure to know them all!

Items
Items can appear by themselves, but can also be found inside crates and chests. Items are fragile, and will be destroyed if they are attacked with the exception of  a  attack which will simply deflect the item away. If a chest or crate is thrown into an opponent, it will deal damage but not drop any items...
