Glyph of the Abyssal

Glyph of the Abyssal is a cosmetic warlock glyph that would cause the player's Summon Infernal to summon an Abyssal instead. It doesn't seem to have been implemented.
==Source==
This item likely would have been created using Inscription (1); taught by Technique: Glyph of the Abyssal, which has no known source.
==Notes==
*The technique was at one point visible in the "unlearned" tab of the Inscription interface, though it listed no source information. It has since been removed, and the related spell ID is now unused.
*Originally, the ability to summon an abyssal was granted by Grimoire of Supremacy.
