Codex

A Codex of Eternity turns a zone satanic: the zone and the number of clears are rolled when it drops, the debuffs when it is consumed. Socket Orbs to boost the zone, or match a recipe to create a Codex Runeword with a powerful buff; an Infernal Codex can take an extra buff/debuff pair from an Essence of Chaos and a modifier from a Satanic Crystal. Names and descriptions come from the game files; numbers from hero-siege-helper's datamine, cross-checked against the official patch notes.
