History of Iron Battalion Bond

Overview

Iron Battalion Bond is a Legendary Warlock bond (class item) from the Season 29 Iron Banner armor set, Iron Battalion. Flavor text: "Raise the banner. Light the flame. Never let it burn out." —Valus Saladin Forge.

The Destiny Game Wiki lists the set bonuses as 2-piece Primary Honing (better handling and reload on primaries plus extra damage against standard enemies based on your Weapons stat) and 4-piece Supercyclical (refunds Super energy when your Super ends if you earned final blows during it).

Acquisition

Drops from Iron Banner activity and its rewards. Note that the separate "Iron Battalion" entry on the same wiki is a shader that has existed since vanilla Destiny 2; it is not this armor.
