Is there a rune that takes away shyness?

Download The Runic Kabalah : https://www.gentilenation.com/the-runic-kabalah.htmlExternal ↗Study the runes and think of ideas. I'd say any rune to do with the Solar Chakra, such as Sol or Raidho. You could also try Uruz, or Kenaz, Kenaz bestows charisma. 
Just study the kabalah and come to the conclusion yourself.
