You can use the following trinkets.
Bag of Traps
As a Bonus Action, you can magically produce and take the Utilize action to use one of the following items: Ball Bearings, Caltrops, Chain, Hunting Trap, Manacles, or Oil (which you can only use to douse a space). If the item requires a saving throw, it uses your spell save DC. For the next minute, you can use a Bonus Action to produce and use another such item, until you have created a total of five items. Once created, these items vanish after 1 hour.
Dooby Snack
As a Bonus Action, you produce a tasty treat that lasts for 1 hour. A creature can use a Bonus Action to eat this treat to gain a number of Temporary Hit Points equal to your Intelligence modifier (minimum of 1). Until the start of its next turn, the creature has Advantage on the next D20 Test it makes.
Magnifying Glass
As a Bonus Action, you can cast Clue without a spell slot or components. Additionally, when you cast this spell using this trinket, you can determine each type of creature that leaves footprints or fingerprints.
