Angel Summoning

This ritual summons angels, not unlike demon summoning rituals. However, angel summoning rituals appeared less common than its demonic counterparts.

This ritual has been performed at least once by Sam on Balthazar. Whether or not the ritual could summon any angel or any type of angel or whether the ritual was exclusive to Balthazar was never revealed.

Procedure
A bowl or dish filled with various materials, most of them akin to leaves, herbs or petals set before a circular sigil. The sigil itself is separated by four lines into four areas or quadrants. Each quadrant contains a different enochian symbol or letter. Outside the circle, four other enochian symbols are written. Four lit candles are placed atop the four quadrants, and four other objects are placed at the farthest points outside the circle. A trinket placed near the dish is also required. To complete the ritual, the summoner must set the materials in the dish on fire.
