History of Pyramid Spike

Pyramid Spikes power the dome-shaped blockades in Resonant Destruction (Ferry the Resonant Splinter), a public event in Savathûn's Throne World. The Resonant Splinter moves along a fixed path and stops at two blockade checkpoints. To lift a barrier, players enter the dome and destroy the several Pyramid Spikes floating inside, after which the Splinter can continue.

Spikes also guard the cruxes in The Wellspring: destroying a crux's spikes dematerializes it. The Hasty Demolition triumph is tied to Resonant Destruction.
