Surge needle

Surge needles are massive constructs that aid in the redirection of ley lines for Malygos. They look like giant floating rings. They are constructed out of stones from Coldrock Quarry.

Surge needles are massive needles constructed of arcane energy. By opening the Focusing Iris with his own blood Malygos had been able to direct powerful surge needles, using them to pull arcane magic from Azeroth’s ley lines and channel that magic into the Nexus.

The Twilight's Hammer used a surge needle to transfer magic from the Nexus into Chromatus, reviving him. Arygos' life energy, the blood of a scion of Malygos, was used to create a surge needle that channeled vast stores of arcane energy from the Nexus and into Chromatus's lifeless body, imbuing the abomination with life.

The Ethereum would later use them to retrieve Void energies and become void themselves.
