Baba Yaga DLC - Boss Fight (Part 3)

After you catch the witch in the blast from the second vat, the water level begins to rise. Swim across the pool and climb out on the southern ledge.

Grab some herbs, plus boxes of pistol and rifle ammo directly ahead and in the alcove on the right. Then scramble up onto the ledge on the left.

Enemies approach from both sides so stay sharp.

First take down a wolf that charges from the right.

Then move behind cover and kill a knife-wielding warrior as he approaches from the left.

Finally, pick off 2 archers on the ledge(s) ahead. Loot their packs and pick up more pistol ammo as you make your way up and around to the right.

Climb into the archway at the east end of this grassy path...

...and fight 3 more archers and a swordsman, who try to ambush you from ahead...

...and behind.

The third distilling vat (labeled C on the map) is here, at the top of the stairs.

On the ledge above and behind the vat, spool, and lever there's a box of cloth and a hole in the floor, which you should try to avoid for now. There's a ladder inside the hole in case you fall in accidentally, but wait to explore there until we can see clearly.

Sand by the spool and repeat the process of dragging the witch toward the vat...

...and pulling the lever to open the lid...

...catching her in the explosion.
