Cheese

Cheese is a drop only item that is dropped by Roshan beginning from his third respawn.

Whilst hard to obtain over the course of most games, Cheese can be an extremely useful item during team fights, as it allows you to cast more spells and survive longer with its incredible restorative effects.

Additional information
Due to the time it takes to kill Roshan three times in a single game, the Cheese is rarely seen. However, it is the best consumable item in the entire game, as it restores a large amount of health and mana instantly. In addition to this, the Cheese can be completely shared with allies. The charges on Cheese can stack. Unlike, Cheese does not despawn after a certain time. Cheese can also be sold to the shop for 500 gold (only by the player who picked it up first).
