Graviton Spike

Graviton Spike is an Exotic Hand Cannon from Destiny 2: The Edge of Fate that fires both Arc and Stasis damage.

Overview

Intrinsic Temporal Manipulation: swap between a fast-firing Arc mode and a slow-firing Stasis mode with alternate weapon action. Precision hits and final blows overcharge the opposing mode. The Temporal Anomaly upgrade lets overcharged modes spend energy: Arc summons lightning strikes, Stasis creates explosions and crystals.

Acquisition

Finish The Edge of Fate campaign (about 8 hours on Legendary), then pick up the exotic mission "Graviton Through the Ages" at the Altar of Relativity. It has 15 steps: gather weapon parts across Kepler (Outer Steppes, The Gorge, Exile's Accord, Central Academy) using Matterspark and Mattermorph, defeat 100 Vex, then complete one round of the Sieve. The reward is a Deepsight Resonance copy.

Catalyst

Four catalyst options are found while exploring Kepler on Fabled and Mythic world tiers: Rapid Hit Refit, Subsistence Refit, Transcendent Zen Refit and Temporal Alignment Refit (Destinypedia).
