Overview
Adventure Guide says
Tectus cannot be killed by traditional means. He builds energy, channeling Tectonic Upheaval whenever he reaches 100. Depleting Tectus's health before the end of Upheaval shatters it into two Shards of Tectus; otherwise, Tectus heals and resumes gaining energy. Each Shard splits into four Motes of Tectus when shattered. Players must kill all eight Motes to defeat Tectus.
