Homebrew:Charm Twister

(OOC: This is an implementation of the Charm Twister feat from The Crooked Moon)

You know hedge remedies and hexes passed down through Old Ways teachings, and you can impart them into small wicker charms you weave. You gain the following benefits.

Old Blessing.

You can cast the bless spell once using this benefit, targeting only creatures carrying a wicker charm you've woven, and you can't do so again until you finish a long rest. You can also cast the spell using any spell slots you have. Your spellcasting ability for casting the spell in this way is Intelligence, Wisdom, or Charisma (choose the ability when you select this feat).

Twisted Hex.

As an action, you can weave spite into a wicker charm you touch. Choose an ability. When another creature is carrying the charm, or while this charm is within an area that the creature considers home, it has disadvantage on ability checks and attack rolls using the chosen ability. When the creature fails one of these rolls, it can make a Charisma saving throw, destroying the charm on a success (DC = 8 plus your proficiency bonus and the ability modifier you chose for Old Blessing). You can only have one Twisted Hex charm at a time. If you make a new one, the previous one loses its magic.
