Holy Instrument

Employed by churches and temples for when monstrous beings such as liches or the necromancers below them prove to be too troublesome. A holy instrument is called upon to track them, find every bit of knowledge, and if possible end them. They are the one true hidden force of the faiths that keep the many cults awake at night.

Celestial Convening

At 13th level once in the morning or night whenever you ask for guidance, meditate, or pray you can ask one question to your patron if the question is where is the location such as a building or cave entrance they will show you an area of 1 mile around it. If it is a person they will show you them at their current location but just the waist up. If it is an object it will be shown and what is around it. Any spell, rune or item that wards off divination magic affects this as well and will not show any location, person, or object in the lower planes.

Any hostile creature within 10ft must make a con save equal to your charisma's spell save; if they fail they are blinded for 1 minute and stunned until the end of your next turn. If any of the creatures is a fiend or undead they have disadvantage against this. This uses 10ft of movement and this ability can be used equal to half of your proficiency bonus per day.
