Great Martyr's Blade is one of eight primary weapons in Mortal Shell 2, and every Shell can carry it. Its weapon ability is Spiral Surge, paid for in Resolve. It takes 23 Tarstones. You find it in Martyr's Prison, Gloomshade Grove.

A two-handed sword, achingly cold to grasp. A remnant from a long dead empire. The First Martyr reserved this greatsword for heretics, but the blade fell upon many pious necks. In time devotion was not enough, the Enshrined whispered of new sins and new foes hidden within their ranks.

Our take

Found in Martyr's Prison in Gloomshade Grove, which is early enough that it can carry a first run. Twenty-three compatible stones puts it near the top of the range; Spiral Surge is what you take it for.

Tarforge upgrades
