Shadowstepper

Silent Step: You can attempt to Hide even when only lightly obscured (e.g., dim light, light foliage, smoke, or crowd).

Shadow Veil: When you take the Hide action, you gain advantage on your first attack made before the end of your next turn. If you are already hidden, you can instead move up to 10 feet without revealing your position.

Whisper Quiet: You gain proficiency in the Stealth skill. If you are already proficient, your proficiency bonus is doubled for Stealth checks.
