With at least 10 minutes of uninterrupted work, you can utter a prayer infused with divine magic.  Up to six creatures within 30 ft. of you gain one of the following benefits.  The prayers can have one of the following effects.  If the effect has a duration, it lasts for the same duration as the equivalent spell, unless otherwise specified:  

• Healing:  Effects of a prayer of healing spell cast at 3rd-level.  
• Restoration:  Effects of a lesser restoration spell.  
• Failsafe:  Effects of a death ward spell.  
• Blessing:  Effects of a bless spell (10 minutes).  
• Boldness:  Effects of the enhance ability spell.  While under the effects of this prayer, a creature has advantage on saving throws against being charmed or frightened.  
• Empowerment:  A creature's weapon attacks deal an extra 4 (1d8) radiant damage on a hit for 10 minutes, and gains a bonus to attack rolls equal to your spellcasting ability modifier.  
• Alacrity:  A creature has its speed increased by 15 ft., and gains a +4 bonus to initiative rolls for 10 minutes. 
• Protection:  Effects of the spirit guardians, and a +1 bonus to AC and saving throws.
• Vitality:  A creature has advantage on all ability checks and saving throws that involve Constitution for 1 hour.  For the same duration, it regains the maximum number of hit points from any healing.  Additionally, the creature is immune to disease.    

A creature can benefit from only one prayer at a time.  Once you bestow the effects of a prayer using this book, you can't do so again until you finish a short or long rest.    

Additionally, you can also cast the following cantrips at will:  guidance, light.    

You can also cast each of the following spells, but only as rituals.  You must also provide the nessasary material components if the spell requires any:  augury, ceremony, commune, commune with nature.    

Once every 5 days, you can bestow one of the following spell effects when you utter a prayer.  You must spend 120 gp worth of ritual components for the effects to work.  This feature only applies to very rare variants of this magic item: 

• Cleansing:  greater restoration. 
• Resurrection:  resurrection.  
• Exorcism:  dispel evil and good.
