From Shadow Era Wiki

Weapons are a type of item in Shadow Era.

Weapon cards allow a Hero to attack and defend, something which they normally cannot do. All Weapons have attack and durability (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. When the durability reaches zero, the Weapon is destroyed. 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.
