Felnas

The Kanohi Felnas was the Mask of Disruption, a Kanohi that allowed its user to disrupt a single Elemental, Kanohi, or physiological power of a target through touch.

manifest rust or decompose a target at will. A Jutlin user can increase or decrease the rate of existing corrosion, though the mask does not allow its bearer to reverse the effects of natural decay and is most effective when applied towards metals. Furthermore, the mask does not directly enable its user to age organic material, though it can have a disruptive effect when used on a fellow combatant.

History
The Kanohi Felnas traces its origins back to some of the earliest mask-making techniques adopted on Spherus Magna, where an unclear number of Felnas masks were created for the Great Beings. At this point in the history of the Matoran Universe, the Felnas bore no elemental affiliation and efforts to craft the mask proved highly volatile.

Following Velika's Awakening of the Matoran Universe's inhabitants after the Great Spirit Robot left Spherus Magna, the Felnas came to be considered a highly Immoral Kanohi by Matoran crafters. As such, Matoran generally chose to abandon their Kanohi Felnas, fearful of its destructive properties.

Over the 100,000 year span of the Matoran Universe's functionality, the Felnas became an uncommon Kanohi, proving more popular among members of the Makuta species. In Metru Nui the mask could crafted with relative ease using Reconstitute at Random and Freeze Kanoka disks, though Turaga Dume later outlawed the production of Immoral Kanohi.

Unfettered by the restraints of the Matoran conscience, Makuta Gorast was known to have worn a Great Felnas as her signature Kanohi.
