– When he possesses Chisel-Light Mirrors, Alhaitham’s Normal, Charged, and Plunging Attacks will be converted to Dendro DMG. This cannot be overridden.
– When attacks of the aforementioned kind hit opponents, the Chisel-Light Mirrors will unleash a Projection Attack that deals AoE Dendro DMG based on the number of Mirrors on the field.
– A total of 3 Chisel-Light Mirrors can exist at once.
– The Chisel-Light Mirrors will disappear one after the other over time, and will all disappear when Alhaitham leaves the field.
