DISCLAIMER: I would like to make clear I am uploading this as an "Submitter", not as an "Author". This icon is composed out of multiple WoW icons cleverly upscaled, mashed and edited together, however, there are some special effects and filters I threw on it that I do own personally. And thus it's not just a plain port and shouldn't go in the ported section.

A shaman or arcane-themed icon. Can be used as a buff, a healing ability, a teleport, pretty versatile.
