Oath Mark Codex

160 Codex levels, 10 hero Oath Marks and 50 levels of Oath Mastery.

The Codex levels up with Codex Fragments, and every level adds flat Health, Attack and Defense to all your heroes. Levelling it also unlocks hero Oath Marks, which you activate with Radiant Ink once that hero reaches the ascension the mark asks for, and each mark you unlock counts toward Oath Mastery, a second bonus for all heroes. Taking the Codex from level 1 to 160 costs 132,950 fragments. It opened one faction at a time: Wilders on February 10, Lightbearers on February 17, Maulers on February 24, Graveborn on March 3, 2026.
