[RPG] Does a Gloom Stalker making ranged attacks while in darkness have advantage on every attack

I am trying a Gloom Stalker ranger for the first time. The Umbral Sight feature (XGtE, p. 42) states:

While in darkness, you are invisible to any creature that relies on darkvision to see you in that darkness.

I want to clarify this part of the rules on unseen attackers and targets:

When a creature can't see you, you have advantage on attack rolls against it.

If you are hidden — both unseen and unheard — when you make an attack, you give away your location when the attack hits or misses.

As I can fire my crossbow and move, do I still give away my location, and do I get advantage on all attacks?

Best Answer

Yes

The rule states:

When a creature can't see you, you have advantage on attack rolls against it.

So long as you cannot be seen, you have advantage. Having a known location or being detectable by a non-sight sense (e.g. hearing) doesn't matter.
