Base damage from this skill scales off of the equipped shield's Armour rating. Conditional modifiers that increase the Armour provided by the shield do not contribute towards the skill's damage. Passive skills with the mod X% increased Defences from Equipped Shield does not affect the skill's damage.
This skill can be used with bucklers, but the Magma Spray will not gain any damage scaling due to it not providing any Armour.
Your weapon's local modifiers will not scale the damage of this skill. Damage is classified as off-hand damage regardless of the type of weapon you have equipped in your main hand or if you're unarmed.
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][confirmation needed]
