If you attack while wearing this ring, you can forgo any bonus damage you would normally have through sneak attack, smite, a spell or other ability. Then, up to four rounds later (you decide), that bonus damage is dealt. This is a magical effect, which can be dispelled. After using this ability, you cannot use it again until you have a short or long rest.
This ring also gives you advantage on dexterity (stealth) checks made to hide after making an attack.
Three times per day, you may declare a sneak attack on a target, even if it is not normally vulnerable to sneak attacks. If you successfully hit, the target takes only your normal weapon damage. However, one to four rounds later (wearer decides), the target takes half your normal sneak attack damage. This is a magical effect, which can be dispelled.
This ring also grants a +6 competence bonus to bluff checks when feinting.
