I'm apparently doing something wrong. I'm getting raided by deathclaws constantly(at least once per session), and they do some real damage to my dwellers.

The in-game hints say they are attracted by the radio and opening my vault, but I don't know if there is a way to turn the radio off while my vault is open.

How can I stop all these deathclaws from eating my dwellers, while still attracting new ones?

I've noticed that deathclaws tend to attack right after a new dweller joins the waiting line outside my vault OR right after I let someone into the vault from the waiting line. They don't seem to attack randomly while nothing else is going on.

To answer your specific question:

How can I stop all these deathclaws from eating my dwellers, while still attracting new ones?

You can't stop them

You can stop them from coming by not clicking on the radio room (so no one gets added to the line outside the vault) and by never letting dwellers in or out of the vault (so the door never opens). Obviously this is not really feasible as it prevents you from adding fresh blood to your vault and from getting the weapons you need to defend it.

In case you thought lunchboxes would be your savior: sorry. Dwellers from lunchboxes don't bring deathclaw attacks when they join the waiting line, but they can still trigger an attack when they enter the vault. I haven't done testing to determine if there is a lower percentage chance for lunchbox dwellers, but I have triggered a deathclaw attack when I brought Bittercup into the vault.

But you can resist

You can minimize the damage that the deathclaws cause by arming all of the dwellers in the topmost levels with the best weapons and outfits you have. Posting guards in the vault entrance is also helpful. Your goal is to have each room wear the deathclaws down as they go deeper into the vault. The deathclaws move from room to room fairly quickly, so manually sending a dweller with the best guns to chase them down is difficult. You can try sending the defensive guys a few rooms ahead of the deathclaws to wait for them, but equipping the the dwellers assigned to the room with guns is faster and should have better results.

Plural of anecdote is data, right?

Some facts from personal experience:

In my fancy vault with 150+ dwellers and Mr Handys, the deathclaws will be killed on the second or third level down. In that vault, everyone on the top floors is carrying weapons that do 10+ damage per hit, and the deathclaws still get past vault entrance, top floor room (with 6 dwellers), and one or both of the second floor rooms before dying. No one dies when this vault is attacked, but they whine about the damage they took.

In my not so fancy vault with 100 dwellers, everyone on the top floors is carrying rifles or better (so minimum 5 damage per hit on most of the second floor and third floor, min 6 damage on the topmost floor). Deathclaws here will get through the top two floors with ease, start to die on the 3rd floor, and be finished off on the fourth floor. After the last attack I had to revive three dwellers and pass out all 25 stimpacks. The deathclaws also stole/drainined/rekt about half of my water/power/food resources. This was a pain in the ass but not as difficult to get out of as the early vault death spiral.


Don't let anyone in or out of the vault; don't let anyone line up in front of the vault. Complain to Bethesda so that deathclaws will get nerfed in the next patch.

  • I've had three deathclaw attacks in a row without having a radio room and without do anything in between other than using stimpacks and collecting resources. No one left or entered the vault, no other events happened. Just deathclaws, deathclaws, deathclaws. I don't think there's anything you can do to prevent them other than having less than 60 dwellers. Not having a radio room and not opening the door at best only reduces the chance of them appearing.

    Tip: I have two elevator columns on every floor but the first. The first has one elevator, immediately after the vault entrance. The two rooms on the first floor hold the best equipped dwellers. All the gatling guns and fat men and such. The deathclaws come in, run through the first room, run through the second room, then run back through the first room before going down. Therefore, the best dwellers get two shots at them. On survival, by the time I get to 40 dwellers, deathclaws rarely reach the second floor. I have a vault with 70 dwellers where I don't even use any stimpacks for deathclaws.

  • More "data": My top floor has two dwellers in the entrance and six in the first room. Everyone is max level (not maxed stats) and has Dragon's Maw. The deathclaws never get past, and most people only need on stimpack.

I have found that if you cause an incident by rushing a room right as you open the vault door to let someone in, deathclaws do not follow afterwards. This has worked the 3 times I've tried it. Rats are much easier to kill than deathclaws. Best of luck.


Train in endurance BEFORE leveling. ((HP only grows while leveling and is based on END) Training END after leveling doesn't boost HP at all, only radiation resistance.) Wear endurance suits until fully leveled, and send people out into the wasteland to level quickly (with a full supply of 25 Stimpacks), Radaways are less important, because at over 10 Endurance, their explorer journal will occasionally say "took 0 points of radiation damage." (you can give them a few to be safe, but radaway doesn't really matter, save it for water shortages(which might happen if most or all of your water pumpers are temporarily out in the wastes leveling up).

Aside from that, once someone's at level 50, put them in good clothes, and arm them well. That part will be easy, because with all the exploring you've just done for the leveling, you'll also have a good stash of special armor and weapons.

After that, Deathclaws (and those dreaded molerats) will be a minor issue. As for raiders and roaches, they'll pretty much melt away like butter in the microwave.


  • Also, don't be afraid to run a "no-revive" vault. Letting the weak (those who leveled before the END training room was available) die off makes everything easier in the long run, and saves you caps.

Deathclaws do appear before you have 60 dwellers, just only in hard mode. If you train all of your Charisma dwellers with maxed out Luck and place them in the Radio Room, that will stop the Deathclaws. Yes, it's true. Max Charisma and Max Luck (you can train them up to 10 and then put outfits on them and that will increase their stats even more). You cannot "turn off" the Radio Room, even if there aren't dwellers in it you still have a slight chance of being attacked by Deathclaws (surprised me too).


Deathclaws won't show up if you have less than 60 dwellers in your Vault (60 exactly may also be okay). So, aside from never opening your Vault door and never using the Radio, one possibility is to send of your less productive dwellers out into the wilderness and let them die (or just remove some of the dwellers killed in Deathclaw attacks) until your total population is 60 or less.

It's worth noting that rooms you've unlocked stay unlocked even if your population takes a dip, so if you are careful and callous, you can raise 40 dwellers (assuing you are already at 60) and then as soon as you have 40 kids, start sending the "Doomed" generation out into the wastes to die. You'll get a lot a Deathclaw attacks, especially opening the vault door a mess of times, but eventually you'll be safe again, with all the rooms unlocked.

    I don't know if this was changed for normal mode as well, but in survival mode I've been attacked by deathclaws with as few as 35 dwellers.

You should know that equiping the dwellers on the first, second and third floor with the best weapons and outfits won't always work. They have to be of high level and also, I would suggest you to train these abilities: strenght, perception, endurance and agility, so that all those dwellers I've been talking about would have those stats maximized. At the moment, my vault has 80 dwellers because I nearly lost everything after one week of playing and now I'm taking it slow but safe. Also, I have no dwellers waiting on the first floor(I have a bedroom and a storage room there) but still, the deathclaws die either on the second floor or in the first room on the third floor. Hope this helps! If you do as I said, you'll see that deathclaws will be easier to kill than molerats which are purely annoying.. Also, to fast level up your dwellers, you could try sending them into the Wasteland with some stimpacks ofc, they achieve XP faster there.


I have a technique to easily get rid of deathclaws/raiders. But raiders aren't really a problem.

I don't put rooms on the second row. Also, I did not connect the first and third row with two elevators. Only one. In this manner, the deathclaws will be dead already on the first floor. Just make sure to have your first room fully healed before the monsters get back to them from the second room of the first row. I have 180 dwellers and this technique is working fine for me.


As an additional note, radio rooms aren't all too reliable for getting dwellers. The introduction of a radio room adds the possibility of raider attacks and deathclaw attack as drawbacks. So if you really want to remove the possibility of those attacks, remove the radio room.


For me I keep getting attacked by raiders. But, I would suggest not using a radio station because every time a waste lander is successfully called, there is a very high possibility that they were being followed or chased by deathclaws. Send people to explore the wasteland with tons of stimpaks and rad-aways, and expand your vault from the inside by having your dwellers have kids but make sure you can keep up with resources. Then when your dweller returns, it's likely you'll get attacked by raiders rather than deathclaws. And train your dwellers and assign your strongest toward the top. Every time the vault door is opened, it increases the chance of Raiders attacking.


Don't build a radio room at all and stack your vault with resources for a few days by staying below 55 dwellers. I've had zero deathclaw this way, several level 25+ dwellers, and all the training rooms so that when people are on, they hit the cycle to get endurance capped, then other stats based on what room you will assign them to. Once you have your food handlers with max agility, water with max perception, and power with max strength, then go explore the wasteland. Leaving too soon doesn't really help you.


I am playing on hard mode and I am at 41 dwellers. I keep getting hit. My strategy now is to let them pass with no resistance and "hide" my dwellers in rooms they have passed. It works as long as you are fast. Stimpacks are helpful if you cannot move 6 ppl in 6 seconds.


What works for me is when the alarm goes off and says the deathclaws are attacking, I hit the PS button on the controller, then close out the app, then re-open it. Most of the time the deathclaws are gone and no one was harmed, but if they don't go away, then I simply move my dwellers onto an upper rooms floor inside a room the deathclaws have already searched. I only lose about 20 dwellers this way, if you fight them, you can lose a lot more than just 20.
