Magma Barrier is an attack skill that infuses your shield with magma. A magma-infused shield releases a spray of magma when struck, damaging enemies. Magma Barrier requires an equipped shield.

Skill functions and interactions

Despite it being an attack skill, the attack damage % used by Magma Spray is derived explicitly from the base off hand fire damage inherent to the gem itself. The amount of damage listed on a weapon in the main hand will not contribute to the Magma Spray damage. Other mods such as X% increased elemental damage with Attacks however will affect Magma Spray damage.

Focusing on the Armour value on your shield is one of the methods for scaling Magma Spray damage.

Passive tree nodes that contain the text X% increased Defences from Equipped Shield such as Towering Shield, Core of the Guardian, Spiked Shield, and Flashy Deflection do not impact Magma Spray damage. Instead, they impact the final Armour value added to the player rather than the implicit Armour value of the shield itself.

Using Resonating Shield counts as raising your Shield for the purposes of activating Magma Barrier, infusing your shield with magma during the first 0.5 seconds of the animation. Conversely using Shield Charge does not count as raising your Shield.[Likely due to a bug]

Blocking with Magma Barrier during the first 0.5 seconds of its activation will not place Magma Barrier on its internal cooldown, allowing it to be used in quick succession with each successful block that is within the allotted window.[Likely due to a bug]
