Wand, rare (requires attunement by a spellcaster)
This wand is made from the elongated finger bone of a celestial being, stained in a devil's ichor and etched with terrifying runes. Fiend's Trifles are so named because they're a favorite gift among devils and demons. Those that are patrons to a mortal warlock will sometimes use a Fiend's Trifle as a reward for particularly good service.
Near the tip of the wand is a carved representation of an archfiend with up to six horns. Every time a spell is cast with the Fiend's Trifle, one of the horns disappears and a charge is expended. When a character receives or discovers the wand it has 1d4+2 charges, and the number of horns on the archfiend's head always corresponds to the number of charges left. At three hours after every midnight, the wand regains 1d4 charges, to a maximum of 6.
Spells cast through the Fiend's Trifle are heat-seeking if they deal fire damage. You have advantage on attack rolls with such spells, and when creatures make a saving throw against them, they have disadvantage. If a target has half cover, you can ignore the +2 bonus to its AC and Dexterity saving throws.
When you hit a Celestial creature with an attack spell cast with the Fiend's Trifle, it must make a Charisma saving throw or be frightened until the beginning of your next turn.
