Shadow's Nature

You have developed traits similar to those of a shadow, granting you the following benefits:

• You gain advantage on Dexterity (Stealth) checks, while in dim light or darkness.
• You can take the Hide action as a bonus action, while in dim light or darkness.
• When you finish a long rest, you can choose to give your self vulnerability to radiant damage in exchange for immunity to necrotic damage and resistance to poison damage, for 24 hours. While you have vulnerability to radiant damage, you have disadvantage on attack rolls, ability checks, and saving throws, while in sunlight.
• When you hit a creature with a melee attack, you can reduce the target's Strength score by 1d4. If this reduces the target's Strength to 0, it drops whatever it's holding, falls prone, and is paralyzed until it regains at least one point of Strength. The reduction lasts until the target finishes a short or long rest. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
