Detected

→ Detected
Enemies know that you are present and can use their senses to target you. Generally this requires the enemy creature's most honed and effective sense, like sight for most creatures. Some creatures use other senses as their primary sense.

Obscured

→ Obscured
Enemies know that you are present and can use their senses to target you, but due to dim light, mist or otherwise disruptive elements that reduces the performance of the enemy senses, you count as obscured.

While obscured, you gain the following benefits:

• Creatures have disadvantage on ability checks against you, like attack rolls.

Hidden

→ Hidden
Enemies know that you are present and know your general location, but can't use their senses to target you.

While hidden, you gain the following benefits:

• Creatures have disadvantage on ability checks against you, like attack rolls, and must use their luck ability modifier instead of their normal modifier for the roll.
• When you make an ability check, like an attack roll or spellcasting check, you have advantage on the check. Whether or not you succeed or fail, making an attack or otherwise noticeable action, takes you out of hiding and you become either obscured or detected.

In addition, remember to check if you gain any possible cover bonuses if you are hiding behind a solid object or creature, ranging from half cover to total cover.

To continue being hidden, you must either stay behind cover or be in an area that is obscured.

Undetected

→ Undetected
Enemies know that you are present, but don't know you specific location and can't use their senses to target you.

While undetected, you gain the following benefits:

• Creatures have disadvantage on ability checks against you, like attack rolls, and must use their luck ability modifier instead of their normal modifier for the roll. Additionally, any creature that makes an ability check against you must first guess the space that you occupy.
• When you make an ability check, like an attack roll or spellcasting check, you have advantage on the check. Whether or not you succeed or fail, making an attack or otherwise noticeable action, takes you out of hiding and you become either obscured or detected.

When making an ability check against a creature that is undetected and you fail, the GM decides whether or not you know if you missed because of failing the check or choosing the wrong space.

Unknown

→ Unknown
Enemies don't know that you are present and don't know your location, meaning they can't and won't use their senses to target you.

While unknown, you gain the following benefits:

• When you make an ability check, like an attack roll or spellcasting check, you have advantage on the check. Whether or not you succeed or fail, making an attack or otherwise noticeable action, takes you out of hiding and you become either obscured or detected.
