Alternatively, you can use an action to place Flash Marks on up to two creatures or objects within your reach. You must have a free hand yo place the Flash mark.

the Flash mark is visible only to you and those with true sight or similar powers, it can also be sensed through spells or abilites that can sense magical phenomenon like detect magic. you can customize the Flash mark into a small shape of your design that is no bigger than the palm of your hand.

When you attempt to mark a creature, it must succeed on a Dexterity saving throw against a DC equal to 8 + your Proficiency Bonus + your Dexterity modifier or become marked. An object is automatically marked when you place a Flash Mark on it.

A Flash Mark lasts for 1 minute. You can have a number of Flash Marks active at one time equal to your Proficiency Bonus.
