I need help getting the Khremvh's tooth melee weapon. When I go down the pool to grab the weapon it's never there, I have gone down there multiple times and it still won't appear. Is there any way else to get it?

If you are just looting the body down there, it's not there. I made this mistake the first time. It's actually in a little alcove to the side of the body near a creepy altar looking thing. If it's not in that alcove, you probably have a bug.

I almost missed it last night, too. Swam down, saw nothing special. In a previous run, I had grabbed the two mini-nukes, so I knew roughly what I was looking for (somehow missed the tooth last time ). On my way back UP, I spotted the side passage / alcove and that's where you find the little shrine with the tooth and mini-nukes. Helps to run your Pip Boy light down there.

Mirelurk cake helps, along with PipBoy light.

Not on the Altar for me either :′(

Yeah, it's in a big room off to the side on top of a lit alter flanked by two mini-nukes and glowing mushrooms. Pip-boy light and copious amounts of Rad-X definitely helps.

Piper is hilarious when she sees the water hole. "You know ... I've just eaten. I better stay out of the water."

If your game ended up like mine, you'll need to look around the alter. The sword was "hanging" behind the alter and I only saw a whips of the hilt. Luckily, I was able to move about a bit until the marker allowed me to pick it up.

I may have bumped it while I was fumbling around down there.

I'm not very graceful in water.

Its probably all the damn rumbling knocking it out of place. By the way... Theres a giant metal face at the bottom of the hole @.@
