Providence Holder

By inscribing symbols or tenets of your faith, or spiritual mantras, upon thrown weapons, you transform them into Nails of Providence, holy sacraments designed to combat the undead.

When you perform a ranged weapon attack with a thrown weapon, you can treat that weapon as a Nail of Providence, gaining the following benefits for that attack:

• The regular range and long range of that weapon are both doubled for that attack.
• If the target is Undead, then you have advantage on the attack, the weapon is treated as magical for that attack, and if the attack hits then the target cannot gain HP for 1d4 rounds, except by lair abilities or legendary abilities.
• The attack deals an additional amount of Radiant damage equal to one roll of the weapon's base damage die. If the hit creature is Undead you can choose to make this additional damage Fire, Cold, Lightning or Force instead.
• You can choose to attempt to spiritually pin the target in place instead of dealing additional damage with this feat, after you have determined whether the attack hit or missed. If you attempt to pin the target, then the target must make a Wisdom saving throw against a DC equal to 8 + your proficiency bonus + your choice of your Intelligence, Wisdom or Charisma modifier. If the hit was a critical hit, then your target makes the saving throw at disadvantage. If the target fails the saving throw, then the target is Restrained until the end of its next turn.

You can treat a ranged weapon attack with a thrown weapon as a Nail of Providence a number of times equal to your proficiency bonus per short rest. As a bonus action, you can expend a spell slot or ki points to regain a number of expended uses of Providence Holder equal to the number of ki points spent or double the level of the expended spell slot.
