Sorry to semi-Necro this but I have an anecdotal incident.
I was very into Discordia over 20 years ago and while doing the normal 'urban shaman' routine common amongst those who lived in Betsit Britain at the time of the Second Summer of Love (read - every psychedelic whe could get) and one night I'd checked my bank balance and it was zero. I was fairly chemically altered and decided to ask Eris to stick some cash in there. I went around the block with my friend , had a vision of a huge bear for some god unknown reason,and came back and , of course, £230 (I'm hoping you all get the 23 reference ) was the balance when I rechecked it.
There was never any mention of that deposit on the statement either.
We found the words of power most effective in any prayer or request to be 'Eris is a babe'. Since she kinda likes that in a - happy pixie elf that can destroy your life and /or city walls - kinda way.
She asks that you enjoy yourself a lot and not to get upset about any pranks in my experience. Dont turn down her gifts or she will either stop playing or play a little rough. But keep a sense of humor when working with her and she is honestly delightful. Do . Not. Snub. Invite to the party. - there's precedent
RAW had her related as far as I cam remember to pretty much every female archetype on the tree. To 'our lady of space' in some of his ideas in Cosmic Trigger , as a microcosm of Nuit. as the counterpoint of the Dwarf self /HGA , also as the Empress /Joyces Mother Goddess... I'm pretty sure he was obliged to use blinds but I think he was peaking a little too hard in that book as he himself admitted later.
