Deliria

The Deliria Forgeborn are the unfortunate few Forgeborn who, during the awakening, were adversely affected by the corrupting influence of Maven. His presence in their minds has driven them mad. For some, they simply speak unintelligibly and act irrationally. For others, it drives them to commit unspeakable acts. Maven’s influence has also given them the ability to cause natural materials to degrade on contact with them.

Unlike other Forgeborn, their eyes glow a golden yellow. The Deliria were originally the Forgeborn constructed as combat units, and many are equipped with mounted weaponry on their chassis.

Rust

You have the ability to spread corruption to everything you touch. As an action, you can touch an object or surface made of inanimate non-magical materials, such as wood, stone, or even metal (has no effect on Shadesteel and Eskite). Using this ability, you can affect a number of cubic feet of material equal to your proficiency bonus (max of 5). The effect depends on the material:

Wood rots and weakens, as if eaten by termites, and becomes brittle. Loud snapping and groaning sounds can be heard.
Stone develops deep cracks, significantly compromising its structural integrity. This can be very loud.
Metal corrodes or rusts rapidly, severely weakening it. It groans in protest.

You can do this a number of times per day equal to half your proficiency bonus (rounded down).
