Cranial Foremount is a resource in Warframe that you can obtain by fishing on the Cambion Drift. Cranial Foremount is mostly used to make Mutagens, but is also required as a component for the Bonewidow Necramech.
Like all resources from fishing, you will need to catch a very specific fish for Cranial Foremount. The Myxostomata will yield two Cranial Foremount, regardless of the size of the fish, if you bring it to Daughter at the Necralisk and cut it into bait.
To find Myxostomata, you will need to fish in caves on the Cambion Drift. The fish will be active during both Fass and Vome cycles and will respond well to Processed Vome Residue. The Myxostomata is a very rare spawn though, so you will need to make sure you are clearing out all the other fish in the area to force regular respawns. If you wish, you can just use ground slam attacks to kill all the other fish if you do not need to farm them.
If you have some spare Platinum, we always recommend using a Booster for fishing, as it will double every fish you catch.
How to get fish bait
When Fass and Vome duel in the Cambion Drift, the losing Wyrm’s body will be blown to pieces, scattering residue across the map. Both of these residues can be picked up and used as Bait for the Infested Fish and can be accessed in the fishing menu. To open the fishing menu, just equip one of your fishing spears.
You will need to drop the bait into the water that the fish flow through when they are not floating through the air. You cannot catch the fish when they are in the water, and can only do so when they are floating.
You can bring your fish to Daughter, located in the Necralisk, and marked on the minimap by a small fish symbol. You can cut the fish here, and trade in parts for Daughter tokens that you will need to rank up with the Entrati Syndicate. You can also get the Spari spear from her, which is the best way to catch these fish.
