Commune II is a glyph used in Necromancy. It can be drawn at level 60 Necromancy, requiring four greater ghostly ink and awarding 44 Necromancy experience. It lasts for a total of 12 rituals before depleting. This is increased to 14 rituals at the Ungael ritual site, but none of the rituals performed there use this glyph under normal circumstances.
As it's drawn directly on a glyph spot, players can't obtain it as an item.
