Spike shields deal elemental damage whenever the user is struck with a melee attack.
Spike shields are useful against enemies that primarily make melee attacks, and is of little value against ranged attackers. One of the more notable benefits of this shield type can be seen when being swarmed by weaker enemies (such as larval varkids, or rakk). These creatures' low health leaves them vulnerable to the spike effect, so they are quick to die when they strike a spike shield.
Note that when a player is being attacked by multiple enemies with melee at the same time, only one enemy will take damage from the shield.
Captain Blade's Manly Man Shield - Uniquecursedexplosive shield that adds explosive damage to melee attacks even when it's down at the cost of taking increased damage from elemental sources.
Impaler - Legendarycorrosive shield that launches homing corrosive spikes towards enemies when damaged with bullets and behaves like a regular spike shield when damaged by melee attacks.
The Spike Shield is obtained randomly from any suitable loot source.
