Weapon is a subtype of item in Shadow Era.

Weapon cards allow a hero to attack and defend, something which they normally cannot do.
All weapons have an attack and a durability value (with the exception of What Big Teeth, which has no durability limit).
Each time a weapon is used to attack or defend, its durability is decreased by one point.
When the durability reaches 0, the weapon is destroyed and goes to its owner's graveyard.
You can only control one weapon at a time, if you play a new one while another is currently in play, the current one will be destroyed.
