Short answer: Cornerstone is a 6-Star Mineral Arcanist and a Riposte carry, the damage half of Version 3.8. Her banner opens on 15 October 2026 and runs to 5 November.
She is the bigger swing of the two 3.8 units. A Riposte carry is a team core rather than a slot filler, and Riposte is a comparatively thin archetype on most Global accounts, so she changes what a team can do in a way that Everecho does not.
Being Mineral, she loses to Plant and beats Beast on the Afflatus wheel.
The full build, the Psychube and Resonance case, and the honest argument for skipping her are in the Cornerstone build guide.
