Vampire String Weaver Spawn

Bountiful Luck (1/Long Rest). When an ally the vampire can see within 30 feet of it rolls a 1 on the d20 for an attack roll, an ability check, or a saving throw, it can use its reaction to let the ally reroll the die. The ally must use the new roll.

Fates Design. The vampire can make an attack made with its strings of death a critical hit. However doing so, the vampire gains one level of exhaustion at the end of its turn.

Innate Luck (12 Luck Points).

The vampire has a number of Luck Points equal to its Charisma score and can spend the points on the benefits below. The vampire regains its expended Luck Points when it finishes a Long Rest.

Advantage. When the vampire rolls a d20 for a d20, it can spend 1 Luck Point to give itself Advantage on the roll.

Disadvantage. When a creature rolls a d20 for an attack roll against the vampire, it can spend 1 Luck Point to impose Disadvantage on that roll.

Precise Control. As an action the vampire can use its string of death to interact with an object within range. The vampire can use its strings of death to open an unlocked door or container, slow or even retrieve an item from an open container, or tip or flip some object. The string used to interact cannot attack or activate magic items or carry more than 5 pounds.
