The Eye of Macabre was an A-ranked magic item that collected energy upon activation.
After it reached a certain threshold, it would open an eye and all those who met its gaze would be trapped within a powerful illusion for one minute. However, those under the influence of the illusion would experience a temporary time dilation, causing one minute to feel like ten.
In addition, it also inflicted damage over time to the targets it afflicted.
'It's fortunate he transformed when he did. Otherwise, it may have taken much longer until the eye was opened.'
Due to Maragos entering the Nightly Bloom and unleashing a highly concentrated burst of Ethos, as well as the channeling of the two anzeyta to call forth the Wilting Gauntlet, the Eye of Macabre did not take long to fully open.
But, despite the three anzeyta all succumbing to the illusion generated by the Eye of Macabre, Izroth did not immediately take action and took a moment to observe.
