Power and limitations#
The Felnas affected one active ability of a target at a time. On contact, the targeted power would build inside the victim and then discharge against their will.

The mask offered no ranged option. The wearer had to remain in contact with the target for the disruption to take effect, which restricted its use to close-quarters engagements. In compensation, the effect was difficult to counter once initiated, because the target's own elemental store powered the runaway discharge.

Appearance#
The Felnas was coloured a sickly yellow-green with black accents along its angular ridges.

Strategic role#
The Felnas filled a narrow and unusual role among KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe.. Most masks either augmented the wearer or suppressed a target. The Felnas inverted the target's own ability, producing collateral damage proportional to the strength of the power being disrupted. Against a Toa, this effectively meant the more powerful the opponent, the more destructive the resulting accident. The mask did not need to win an engagement outright to alter its outcome.
