Im new so if I am wrong point it out please.
So Last night i did my Enchanting writ in reapers march. I picked it up and it instructed me to create a " Strong glyph of Health " and then asked me to Acquire a HADE potency rune. This I found to be odd as I know it needs the PORA rune. I then proceeded to my enchanting table and sure enough when I added the Hade rune it gave me the option to create a Strong glyph of Absorb health. I then crafted both As I am not sure where the problem was . IT turned out it was the Strong Glyph of health that needed PORA.
Now im not sure if my limited knowledge of Writs is the problem here that the Acquire * is a 2nd part of the writ that has no context to the glyph you needed to acquire but every time I have checked this " acquire 8 " part was always one of the essence runes of the glyph I had to create.
