OSRS inferno blob prayflicking

Found a nice little trick to prayflick the blobs, if you change your protection prayer every tick from mage to range, you always got the protection prayer right for the blob. You can do this easily together when there is a mage or range on you, just make sure you turn magic prayer on the tick the mage hit you and keep swapping prayer every tick to prayflick the blob with it.
