Destiny 2's Graviton Spike is one of the shiny new toys in The Edge of Fate, and it gets even better once you find its intrinsics. This dual-fire weapon is tied to Kepler, and improving it requires you to unravel the destination's many secrets.
While other intrinsic upgrades usually hide in secret areas within an Exotic mission, Graviton Spike's improvements are concealed in Kepler's landscape. During your time in the The Edge of Fate destination, you might have encountered some yellow plants that don't seem to be just part of the scenery, which are part of a bigger mystery.
