...His hide turned the mightiest tame... – Combination of maylay, fire nova, and fire spike shield types. Increased roid damage bonus.
Despite its incendiary nova and spike effects, Maylay Shields are not intrinsically elemental and as such, the Hide of Terramorphous can receive any elemental immunity/damage reduction.
This shield is well-suited for Gaige's action skill, Deathtrap. If the Sharing is Caring skill is enabled the shield adds spike fire damage when Deathtrap is attacked by a melee source. When the shield is depleted, it releases a fire nova blast and augments Deathtrap's melee attacks with great roid damage.
This shield's large nova damage and spike damage make it useful when being overwhelmed by close-range hostiles.
This is also useful for Zer0 due to the melee-oriented nature of his action skill, Decepti0n.
This is also a great shield for a Buzz Axe Rampage centered Krieg, since he will usually be at such a close range that enemies still alive will be forced to melee him, lighting them on fire, which, when combined with the Hellborn tree, can cause even more mayhem.
