Leman Russ's primary weapon during the Horus Heresy was the Frostblade Mjalnar, an ancient weapon also known as the Sword of Balenight. Prior to taking up Mjalnar he wielded the chainswordKrakenmaw until it was destroyed by Angron during the Night of the Wolf. To complement his sword, Russ also wielded the frost axeHelwinter.[22] For longer-ranged engagements, Russ wielded the bolterScornspitter. Russ is also known to have had an artifact known as the Spear_of_Russ, but he hated the weapon and ultimately gave it to Bjorn during the Battle of Yarant.[21]
