Finally, the symbol must be blessed by the Spirit of Scorpius at the Scorpius Shrine, north of the Observatory, or by using an Unholy book or Book of balance with it. To bless the symbol using one of the books, a player must have a Prayer level of 50 or higher, and blessing the symbol makes the player expend 2 + (10% * current prayer points) Prayer points. Once blessed, the unpowered symbol becomes an unholy symbol and gains stat bonuses.
