The Vaykor Marelok can be acquired by reaching the Rank of General with Steel Meridian, and spending 100,000100,000 to purchase. As with all Syndicate Weapons, the Vaykor Marelok cannot be chosen as the free offering upon ranking up to General rank.
Syndicate weapons, like Void Trader weapons, can also be acquired via Trading, but only for unranked copies without Forma or Orokin Catalyst installed.
The Vaykor Marelok has an innate Justice effect identical to that found in Steel MeridianWeapon Augment Mods. Upon accumulating sufficient affinity, the Vaykor Marelok will release an AoE radial blast that deals Blast damage and staggers enemies for Finisher attacks, restores 25% of the Warframe's maximum Health, and temporarily buffs maximum Armor by 25% for 30 seconds.
The innate polarity can somewhat limit elemental modding potential, thus making it a less desirable polarity for elemental modding. If you wish to focus more on elemental damage, then it is recommended to either ignore the polarity or use Forma to turn it into a more suitable polarity.
However, the high status chance can actually make the weapon proc very often, making Deep Freeze a very easy way to slow down enemies.
The Vaykor Marelok is a great side arm for dealing with enemies at short to mid range for players who have a sniper rifle or bow for their primary weapon. Vaykor Marelok's firepower is strong enough to be considered a sub-primary weapon.
