Sky Piercer

Overview

The Sky Piercer is Ozletc, the eldest of the three Psion Flayer sisters, who represents Arc energy. She is one of the rotating bosses of The Sundial, and appears as the second boss after Niruul in the rotation.

Fight

Her Arc attacks call down pillars of energy, and blue markers on the ground show where they will strike. At one-third health she summons Psion Commanders, who shield her and must be killed before she can be damaged. After repeated defeats the sisters attempt to fuse into Inotam. Boss rotations in The Sundial have changed over time.
