Face in the Crowd

Years spent being overlooked have honed your ability to melt into the background. People simply don't register your presence. You possess a forgettable appearance, a voice that blends in with the noise, and a way of moving that leaves no impression. This anonymity grants you the following benefits:

Lost in the Shuffle: After spending ten minutes in a crowded area, you gain advantage on Dexterity (Stealth) checks made in that area. Guards, busy citizens, even those actively searching for someone with your description – they simply won't notice you.
Plausible Alibi: You have advantage on Charisma (Deception) checks made to convince someone of your whereabouts.
