Angels surely have sigils.
Here is the procedure -
Draw the sigil on a paper. Then activate it through gazing. That is keep it at arms length and gaze at it, rather through it. After few minutes it will start to flash. That is the lines will disappear, like fading away and then reappear, or lines will seem to become 3D for a moment. That means the sigil is activated. Now call on raphael with your heart out, like screaming, shedding tears , going crazy. That’s called rapture state. After 10-15 min of this intense calling state to the archangel raphael that as God himself, as part of God himself you command/request him to heal your daughter. Say this atleast three times. Also you must have your daughter’s photo and if possible her dna signature ( hair or nail) there at that time. Tell raphael that those things are linked to your daughter, one who needs healing. After that state that as the goal has been already achieved he may leave.
Then you can keep the sigil with your daughter as it will work as a talisman for her health. ( remember, if working with demonic, or dark entities it is better to burn off the sigil)
