[Investigation scene, Nosedive] (4)

First things first, head over to the dead man. You'll see him highlighted by a bull's-eye lantern. Interact with him to collect the Bullet-riddled corpse, which is the first piece of evidence (Evidence 1/2).

Now, proceed through the archway in front of you. Be ready, because you're about to walk into an ambush! A half-naked Innsmouther cultist with a shotgun is waiting. Take him down quickly with whatever weapon you've got. Don't worry too much about getting experience from this guy; the main benefit is taking less damage yourself. If you picked up the battle rifle earlier, it's great for picking off a few more cultists from a distance in this area.

Next, make your way to the altar in the middle of the cavern. It's adorned with a horned serpent. Below it, you'll find giant tadpole eggs. Interact with these to collect the Giant amphibian eggs, your second piece of evidence (Evidence 2/2).

After grabbing the eggs, climb the stairs located behind the altar. Up there, you'll find a wounded Mr. Ebernote Blackwood. Approach him for a conversation.

During the conversation, you'll have a few dialogue options. You can choose to ask about Harriet Dough, state you have questions for her, say you have no time for frescoes, or declare you must go.

Once the conversation wraps up, you'll receive some important items and rewards:

• Blackwood's statement [CASEBOOK, Nosedive] (Key Evidence 1/1)

Key Evidence Collected

All Evidence Collected

+184 XP [SKILLS]

You'll see your experience points update. You'll have 1,523 XP out of 1,500 needed.

You'll also receive 1 Knowledge Point [SKILLS], which will cost you 1,500 XP. Your XP will then drop to 23.

Head into your skills menu. You can now acquire the War Veteran skill under the combat proficiency section, using up your Knowledge Point. This will leave you with 0 Knowledge Points.

Finally, proceed through the archway at the very top of the stairs to continue.
