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...
 * Food - Various food items restore varying amounts of health. Meat restores the most.
 * Gems - Only appearing in J-Galaxy, 6 different types of gems are used for J-Power mode. Gems can also appear when a player is KO'd.
 * Bomb - A bomb that will explode shortly after appearing or if struck by an attack. The explosion will do damage even if the player is guarding.
 * Bubble - Grants invisibility effect.
