- For the subzone, see Surge Needle.
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.
