Prerequisite: Requires a Dexterity score of 15 or higher
You have mastered the art of blending in to a group. If you are in a group of three or more creatures, of your size or larger, you gain advantage on stealth checks, and perception checks against you have disadvantage. While you are hidden in a group any of your attack rolls against creatures within the group have +2 to hit, and +5 to hit creatures within 10 feet of you that are not in the group.
If you attack from within the group you must make a DC 15 stealth saving throw to remain hidden. If the group was of six creatures or less you make the roll with disadvantage.
