Arcane Pulse is an Arcane Enhancement that provides a chance to replenish additional health for you and nearby allies whenever a Health Orb is picked up.
Capturing the Eidolon Gantulyst grants a 5.29% chance to get an Arcane Pulse, killing it will not yield this arcane.
This enhancement synergizes with Nekros' Despoil augment, as the augment makes Desecrate use Nekros' health to cast instead of his energy. Coupled with the health orbs generated with Desecrate this allows Nekros to heal nearby allies as he replenishes his own health.
Having Arcane Pulse installed on both helmet and syandana provides two independent chances for it to trigger. If these occur simultaneously, both will provide health, granting up to 225 health.
Arcane pulse will not increase the energy provided from a health orb when using equilibrium.
This arcane was originally dropped in The Law of Retribution and its associated nightmare mode. Following Update 22.14, all Trial missions were retired from the game and the arcane drops in turn were moved to the Eidolons instead.
