Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Ritual of Silver Flame (Ritual)
A simple cleansing Ritual used to bless oneself with protection from evil. Calling on a Spirit of the Moon is much like asking for a blessing from Selune. If the ritual is performed and a spirit accepts you as their charge, you will be bathed in silver moonlight on completion of the ritual.

Write your full turn name on a piece of parchment, roll and tie it with a lock of your own hair.
Place it within a small blazer of oil with a single drop of your own blood.
Burn the scroll and recite the prayer three times.

"Spirit of Silver and Flame, accept my name, bless me with the strength of iron, and cleanse me as I walk in your light."

Do this on a moon-lit night to call a spirit of the moon for protection; the fuller the moon, the more powerful the spirit
Warning: Never perform this on a blood moon, for that would be an Ill omen and provoke them.
