Medicine Kit of Placebo

This item has 10 charges. As an action, you spend
a charge to make a Deception check contested by
the Insight check of a willing creature within 5
feet. If you succeed, you provide them 1d8 + your
charisma modifier in temporary HP. If the target
succeeds, they are immune to this effect for 24
hours. The item regains 1d6+4 charges at dawn.

Almost."
