The Holy Rosary is the most indulgenced prayer in the Church, except for Holy Mass. There’s no need for the indulters to “reinvent the wheel” but that’s just what they’ve done with the deliverance prayers. If one has problems, of any kind, say the rosary. Our Lady can banish/conquer any demon She wants. There’s no need for any “special” prayers. The Rosary is all St Padre Pio needed; that’s good for all of us.
