Note: I guessed (obviously wrong) at the spelling of the words.
Can you and/or anyone in your organisation tell me what she's doing or saying?
And/or where I can find the proper spelling for what she is saying?
Answer - This looks total gibberish to me. There are a few words in there that are not made up - Leviathan is a biblical sea monster, Asmodeus is the name of a demon, ball, porous, bilious, bell, avatar and nervous are common words. The spelling of others hints at some names of figures in Paganism but the cohesive whole doesn't mean anything.
The structure doesn't suggest a spell either. The whole point of a spell is to actualise intent so just reading out a string of words wouldn't cut it. - That was my big problem with Bedknobs and Broomsticks ;)
Strongly suspect this is just a series of random words that sound good and have been strung together for the sake of a bit of light entertainment.
