Fallout 76 mutations list - what are they and how do you get one?

Fallout 76 may have not had the best of critical receptions, but there are a number of new features in the game that improve the gameplay loop compared to Fallout 4. One of these is mutations: passive effects applied to the player that offer both positive and negative effects, much like traits in Fallout New Vegas.

If you're looking for some Fallout 76 single player tips, these mutations can come in very handy. Some aspects of the game are incredibly tough to take on as a solo player, like joining the Fallout 76 Enclave for example. Take a look through this full list of Fallout 76 mutations and consider grinding for the right ones to suit your play style.

To obtain mutations in Fallout 76, you essentially need to irradiate yourself. This can be from any radiation source, such as a pool of water in the Toxic Valley region, a nuclear blast zone, irradiated creatures like Glowing Ones, or irradiated consumables like spoiled meat. For every 5 HP of radiation you get, you have a 5% chance to gain a mutation. This can be any mutation from the list below, and a character can have multiple mutations at once as long as you accumulate enough radiation.

The only guaranteed way to cure a mutation is to use a contamination chamber, such as the one in the Whitespring Bunker. This isn't always an easy option though, so using RadAway has a chance to cure one random mutation at a time. If you want to reduce the chances of getting a mutation, simply wear radiation protection gear such as a Hazmat Suit or a Gas Mask.

If you want to cure your radiation but keep a mutation, the only way to do this is by equipping the Starched Genes perk at rank two. This removes the chance of RadAway curing any mutations alongside the radiation. You can also gradually remove radiation - but not all of it - by allowing yourself to be killed, since mutations persist through death, and dying removes a small amount of radiation.

How to get mutation serums in Fallout 76

When you've levelled up considerably and you've joined the Enclave, you can actually purchase mutation serums for 5,000 caps each. This is a considerable amount so you'll need to save up before going for one, since caps are harder to accumulate in Fallout 76 compared to the previous single player instalments.

You'll find the mutation serums in the science wing of the Whitespring Bunker, from the MODUS science terminal vendor. Every time you visit, the serums available are random so you may have to come back a few times before you find the one you want.

If your goal is to craft your own mutations, then you better get grinding for caps. You can purchase mutation serum recipes from the same place, but they cost 20,000 caps each - four times the amount of a single serum. They're rare too, so there's a good chance the vendor won't even have one when you visit.

The big question is which Fallout 76 mutations are the best though? All of them have their upsides, but depending on your play style, you need to weigh the positives against the negatives. Our favourite mutation has to be Marsupial, because the increased jump height means you can actually access areas of the map you wouldn't otherwise be able to. Having an extra 20 carry weight is also very useful, and the -4 Intelligence isn't as severe as something like Strength or Agility.

Carnivore is another decent mutation to have, as long as you haven't decided to make your character a vegetarian. Cooked meat often has better effects than some of the non-meat options, so as long as you've got enough wood and boiled water to keep cooking the limbs of your fallen enemies, you'll be satiated for days.

Finally, if you're a melee character - which is incredibly strong in Fallout 76 - you're going to definitely want Twisted Muscles. You'll hardly be using any guns anyway so the -50% accuracy won't come into play, and you'll be dealing increased damage with every single swing. Seriously consider re-speccing your character into melee. It's so powerful in Fallout 76.

Combine some mutations with Fallout 76 power armor and you'll be an unstoppable force in the world of Appalachia.
