You keep a wide array of Holy Symbols and blessed items on your person, even if you aren't particularly pious. You can use the following trinkets (expending a use of your ValdaSpire24 to do so).
Amulet of Warding
As a Bonus Action, you place a divine ward on a creature of your choice within 60 feet of you. Until the start of your next turn, the warded creature gains a bonus to AC and saving throws equal to your Intelligence modifier (minimum of +1).
Restorative Ankh
As a Bonus Action, a creature of your choice within 60 feet of you regains Hit Points equal to your Investigator level plus your Intelligence modifier.
Rune of Banishment
As a Bonus Action, choose one creature you can see within 60 feet of you. The creature must succeed on a Charisma saving throw against your spell save DC or be banished to a harmless location in the Ethereal Plane. While banished, the target has the Incapacitated condition and its Speed is 0. At the start of your next turn, the creature reappears in the space it left or in the nearest unoccupied space if that space is occupied.
