What is the bare minimum I should take to LR, Yes i know I can go back when I please. I have yet to do it, so what is needed and what should I take as backup?

The only things I REALLY need are my hand-loaded .308 bullets and Christine's silenced sniper rifle. However, no matter what gun you choose, make sure it's upgraded to the teeth and have some hand-loaded ammo and AP/HP bullets. The enemies have a high DT in LR.

I also bring quite a few stimpaks and LOADS of Rad Away and Rad-X.

Don't load yourself down with a ton of guns, you will find some good armor and new guns in the Divide.

Thank you good sir, do you happen to know if they cripple limbs allot? should I bring a bunch of doctors bags? And also is it filled with enemies aka do I need a bunch of weapon repair kits.
I know it says lvl 25, but is this accurate can i go in with a lvl 18 and be fine (I am a good player honestly not trying to brag) or should I be higher then 25?

You can find most of what you need while you are there. But, Ammo is in short supply. I would not worry over much for weapons and armor as the place gives you what you need. However, Meds are always good. I would go Stimpacks rather than Doctor's Bags (no weight on the Stims) as you can fix limbs with those. The nice thing is that what you need to most of to take with you weighs nothing.

In fact, in the first 3 minutes, you are given most of the weapons you need. I would agree that a Sniper Rifle would be a good thing to bring with, I forget how long it takes to find the one that is there.

Thank you cat, but I am on hardcoe therefore I need the doctors bags for me limbs. I am doing a dead is dead hardcoe very hard and all has gone well so far, have done HH and OWB. (I have previously on other accounts done DM, Not a huge fan) this is the only one I have not. Any advice on Levels?

Just a tip, if you are playing dead is dead, watch your step when you reach High Road. The area is mined with satchel charges. They are far more deadly than normal mines and on very hard they almost always cripple multiple limbs and just one can easily kill you. Not to mention, they are much harder to see than normal mines and only beep two or three times (rapidly) before detonation.

I'd recommend leveling up a bit before tackling this dlc. It's doable, but it is meant to test your character to the max. So nothing will hold back on you like in all the other dlc.

No matter when you go, bring a good amount of rad-away. There's lots of radiation in the Divide. You will find good armor pretty early on there so I have nothing to say about that, but if you are a guns/energy weapons user, you should bring your best ranged sniper weapon. The most dangerous enemies are melee-based so this will help tremendously.

One last thing, don't go to the Courier's Mile yet. It's great at a high level and I recommend you come back for it later, but it's easily the most dangerous area in the game and it's not worth risking your DiD. Most enemies there are insanely buffed up and can will kill you in one hit at your level and difficulty.
