random ideas coming to my mind:
-- put ALL equipped items to boutique-bag... even runes, wizards emblem, specs of light
-- disable "Holy weapon"
-- sell the items from bag "normal" and "handwork"
-- take out all items from auction
-- clear mail (delete mails!)
-- abandon ALL quests
-- leave guild
-- you write about items for tutorial qust "make ring" and material --> this is likely your problem
can you somehow finish or abandon this quest?
-- if all dont help write to customer service
i like how you wrote you already know about what it means to delete the aiodos reinc - this makes sure there wont be any disappointment after reaching your goal
