Keraunios

The Adaptive Frame defines how it handles: "A well-rounded grip, reliable and sturdy." Its frame family also gives it the intrinsic Barrier anti-Champion effect that Update 9.7.0 attached to every archetype. The origin trait Classy Contender reads: Final blows with this weapon grant class ability energy.

Trait column one of Keraunios can roll Fourth Time's the Charm, Trickle Charge, Rapid Hit, Overflow, Supercharged Magazine, Rewind Rounds and Shoot to Loot. Trait column two can roll Rolling Storm, Butterfly, Target Lock, Chain Reaction, Jolting Feedback, Detonator Beam and Killing Tally. Every one of these trait perks has an enhanced version. The barrel slot offers eleven options and the battery slot six.

The Tenet of Bravery in the Monument of Triumph sells the Guardian Games Weapon Engram for Legendary Marks, and Keraunios is in it. The engram comes in Tier 1 to Tier 5 versions, and each decrypts into a random event weapon, with a chance of a Holofoil one. Its preview also lists Hullabaloo, The Title and Triple Laureate.

• Keraunios through the Weapon Perks option: a roll with random perks (1 to 30 rolls), a roll with 1 chosen perk, or a God Roll with 2 chosen perks.
• You tell a pro player the perks you want: one perk such as Chain Reaction, or two together such as Chain Reaction and Overflow.
• Weapon Tier: Tier 3, Tier 4 or Tier 5. Higher tiers add perks and enhanced mods; Tier 5 adds special traits.

• An active Destiny 2 account.
• Access to the Monument of Triumph, which is open to every player.

Is Keraunios still obtainable now that Guardian Games is retired?

Yes. Bungie retired Guardian Games in Update 9.7.0 and moved part of its weapons into the Monument of Triumph, where they are sold as engrams for Legendary Marks.

What does a chosen perk mean for Keraunios?

With a roll with 1 chosen perk the pro player aims for one perk you name, such as Overflow; with a God Roll with 2 chosen perks you name two that must sit on the same weapon, such as Overflow and Killing Tally.
