Item sharing

Almost every item in Dota 2 can be dropped, allowing other heroes to take it, or for the hero to give it to their allies. Despite that, most items cannot be shared with other heroes: the hero who bought an item is considered its owner, and only they can use, sell, or upgrade it. If it ends up in someone else's inventory, the item will be muted.

However, most consumables are completely shareable as they cannot be upgraded, and only grant temporary effects. These can also be used by heroes that do not own them. This allows support heroes to purchase items to share with their team.

Some permanent items are partially shareable: other heroes can benefit from their effects when holding them, but cannot sell or upgrade them. and are special, in that they drop on death and can also be used by enemies.

Finally, to prevent abuse, certain items are disabled on the.

Completely Shareable
Details:
 * Other than s and s, stacks of the same item type owned by different players do not merge.

Partially Shareable
Details:
 * s can be dropped only through the main inventory, which is possible only via s.
 * s containing runes cannot be dropped.
 * works like an unshareable item until an enemy of the owner picks it up. After that happens, it can be used by anyone, but can only be dropped by dying.

Cooldown interactions
While the cooldown of is bound to the user, other items follow these rules:
 * All Items of the same type in the user's inventory, backpack, and stash go on cooldown when any of them is used, independent of their owner or shareability.
 * For example, if you have 2 stacks of —one of your own and one of a teammate, using either one will put both on cooldown.


 * If a hero receives an item type that would be on cooldown for them, it is placed on cooldown, independent of its owner or shareability.
 * For example, if you have 2, use 1, then receive an unused Dust from a teammate, both will be on cooldown.


 * An Item that is on cooldown retains its cooldown, even when given to a Hero that hasn't used it.
 * For example, if a teammate has 2, uses one and gives the rest to you, it will be on cooldown for you too.


 * All items that merge into an existing stack of them will assume the same cooldown as the stack which was first in the inventory.
 * For example, you buy a stack of and give it to a teammate, who uses it, then drops it.
 * If you buy another stack of Dust before picking up the first Dust stack, the merged stack will not be on cooldown.
 * However, if you pick up that first Dust, it will be on cooldown. Any additional Dust you buy will merge with that stack, and also be on cooldown.
