Moving Stealthily. A successful Stealth check makes you hidden. While Hidden, you must move at half your speed, or you are no longer Hidden.

Concealed. Other creatures are not aware of your location. You aren’t affected by any effect that requires its target to be seen or to know where you are.

Surprise. If you’re Hidden when you roll Initiative, you have Advantage on the roll.

Attacks Affected. You cannot be targeted with attacks. Your attack rolls have Advantage.

Undetected. If another creature senses where you are, you are not longer Hidden to that creature.

You can end this condition at any time you wish by revealing yourself (no action required).
