Ignore the camp and pass stealthily

You crouch between the bushes and you carefully prepare an invisibility spell.

Their wooden barricades block the main path, you move like a whisper, slipping between tents. One goblin sniffs the air, but he can't see you, he's confused and scratches his head.

You can do it, it will be easy, you have to decide which part of the camp is safer.
You can pass through the zone with the pit, or you can pass through the zone with the campfire.
