7 Days to Die

This solution is going to be a bit lengthy, but in it I will tell you everything, good and bad, that I have learned the hard way so you can avoid doing the same and therefore save yourself quiet a bit of time. I'm also going to assume you're fairly familiar with the game and crafting and all of that. Also, if you want to know what, in my opinion, is the best strategy for focusing on just raising wellness, be sure to read down past the second edit. I know it's a lot to read, but once you've read it all, you'll be set to either use my final method or make one of your own using the info given here.

First off, to make your life easier I'd say do this in single player and turn off zombie spawns in the options. (Also a good way to work towards the 20 hours without dying in SP.) Also choose the Navezgane map, not random generated. On top of that it is also helpful to change all of the settings in your favor. Such as maxing the loot percentage, minimizing the time for the loot to respawn etc etc.

Now let's begin. I would highly recommend using the house that I did for your base of operations. It's close to a good number of resources we will be using, and it's fairly centered in the map. The coordinates are 930 N 550 E. There's a river nearby to the south for water and a massive corn field behind the house which is going to come in handy. Also, collect any and all painkillers and beer you find. I'll explain why later.

I'll start with the food side first. As coffebeanz mentioned in his guide, the survivor state does increase the wellness you gain, but also decreases how often you get hungry. So it's kind of a double edged sword. If you max it like I did you get 100% bonus to wellness gain and a 50% decrease to hunger. So I guess it's a good trade off, but you'll be waiting longer to eat. So I guess this is up to your preference. Also, the bacon and eggs is a good place to start but your end goal for food is meat stew. It gives almost double the wellness as bacon and eggs, so once you get the resources rolling in for it you'll see the once precious eggs as trash.

The ingredients for meat stew are raw meat (go figure), so hunt any animals you find, bottled water (start hording glass jars in any form you find them. Or you can craft them in a furnace.) Corn (plenty behind the house) and a potato. The potato is the tricky one as it's a bit of a rare find. This is where patience will come into play. You may get lucky and find a potato or potato seed in a random place, but if not the place to look is the shamway food mart. There is one at 190 W 1850 N. Theres another one that is a bit of a hike if you don't mind making the trip. It's in a town and it's around 1750 N 1600 W. Youll be traveling through desert if you go to this one so dress accordingly.

Once you're in the store you'll see large wooden crates around that you can't interact with. Break it open and it will reveal a box you CAN interact with. These are where you want to look and hopefully find a potato or potato seed. If you find potato make sure to turn them into seeds. If you're unlucky and don't find any, come back later and check again. I think the shortest loot respawn you can set is 5 in game days. BE SURE TO EMPTY THE BOXES, even if it's stuff you don't want, otherwise new loot won't spawn in them.

Once you have a potato seed(s), clear area in the corn field, use a hoe to till some ground, and plant them. About 2 real time hours later you'll have a potato plant that yields 3 potatos. Be sure to always turn some into more seeds and replant them. If your patient you can have LOTS of plants after a few rounds. Once you're stocked on meat,, corn, taters, and bottled water then you're good to go with the food side of boosting wellness.

Now for the drinking part. This one you can abuse a bit. This is where the pain killers and beer I told you to collect will help. The other two things you need to stock up on are goldenrod flowers (yellow), which can be turned into seeds and farmed, and crysanthemum flowers. (Red) These ones can't be turned into seeds.

Both of these flowers can be brewed into tea. The teas don't necessarily have a high wellness boost, but every little bit counts, especially if you drink it every time you're thirsty instead of plain water. It also helps when you can abuse it. How you ask? By being a pill head alcholic.

While you painfully have to wait for your hunger to go down on its own to reap the benefits of your stew, you can force your thirst down so you can drink tea rapid fire. Every time you take a pain killer, it decreases your hydration by 5. So take a pill, drink some tea, take a pill, drink some tea.... rinse and repeat.

The same can be done with beer and tea, but this one has a limit until it hurts you. Once you hit the point where you're drunk, STOP. Dont get this confused with "buzzed." Buzzed is fine and you can drink about 8 beers or so before you're drunk. If you keep going and get "sick drunk," then you will actually lose wellness over time. Once you're sober again you can continue.

Another little boost you run across is vitamins. They are green pills found in medicine cabinets and shelves in places like "pop n pills." So just eat those whenever you find them.

Once you hit 150 wellness don't be alarmed when the same stuff doesn't increase your wellness as quickly. The requirements increase as the level does. So unfortunately it will slow down at that point.

And that's that. Follow these steps and you should hit 200 a bit more quickly than the trial and error I went through to learn all of this. Also IMPORTANT to know, because there's no zombies doesn't mean death isn't possible I died too many times and every time you do you lose 10 wellness, which is a good chunk of time lost. So I have 2 tips to help avoid this.... Stay away from bears if you don't have a gun, and if you come across a military outpost, STEER CLEAR. There are landmines surrounding it and a sudden explosive death out of nowhere is frustrating as hell. Trust me. You can recognize these bases as a group of tents with a guard tower and sandbags surrounding it. They are usually in a square formation.

Edit: underoath fade brought this hepful tip to my attention regarding hunger, which I'm thankful for because I was not aware of it myself. "To decrease hunger fast go to a snow biome and get to 30 degrees (Status effect Freezing) this increases the decrease rate for hunger allowing you to eat any food but preferably a Meat Stew every 2-3 minutes. Be careful not to go down to 0 degrees otherwise you will die of Hypothermia, so just stay near a cabin and walk inside when you get close to 5-10ish degrees."
To add to that I'd say another way of an escape from the cold aside from hiding in a cabin would to maybe be on the edge of the biome then just run to the warmer climate when needed.

Edit #2: ok, so I tested out the freezing stay dropping hunger and it does work. Once you hit 30° you get the freezing status which lowers hunger by 1 every 10 seconds. However, the meat stew has a warming effect that lasts 3 minutes, which isn't a problem as far as negating the freezing if you have a bandana and sunglasses or a cowboy/plant fiber hat. It IS a problem as far as hunger goes though. Not only does it warm you, but it keeps your hunger ftom dropping for those 3 minutes as well. So if you want to use the freezing strategy for consuming good more quickly (and it is indeed a good strategy, thanks underoath) then use grilled or charred meat. I'll explain why in the next paragraph.

So, using a combination of everything learned, here is, in my eyes, the ultimate way to go about getting this achievement.
Go to the snow biome. Stay close enough to the warmer biome so you can make it back without freezing to death, but far enough in to lower your temp to 30 and below. Bring lots of grilled or charred meat and goldenrod tea. (The red tea has a cooling effect that works like the warming effect of stew and keeps you frI'm getting thirsty while active. Not that it matters in this strategy as the meat drops hydration anyway, but a useful bit of info anyway.) Lower your temperature to freezing, which starts at 30. Use cowboy hat/bandana/sunglasses if needed. Once you're freezing, your hunger will drop much more quickly over time. Eat a grilled meat. This will make you thirsty. Drink the goldenrod tea. Both the meat and tea raise wellness. Wait until your hunger drops, repeat as necessary.

All of that being said, I think this guide is fully complete now. I'll leave all of the information in here that way you can use whatever strategy you want or a combination of all of them depending on what you're doing. E.G. exploring or building or whatever or just aiming to raise wellness.
Hope this guide helps. Any issues with it, just shoot me a message or comment on it and I'll address the problem if possible. Good luck achievement hunters.

The fastest way I've been getting my Wellness is up save your skill points and put them towards 'The Survivor' skill. There are 5 levels at 10 skill points each so 50 points will be needed to reach the max skill. Once I did that, I ate nothing but bacon and eggs. Once I was at level 5 for the Survivor Skill, I was gaining about 1 Wellness point every time I ate. I haven't gotten to 200 yet, but currently at 137 and rising fast. Hope this helps!

As of 6/25/2020 this works proven by myself and ikilledbecka.

Note: This WILL NOT work split-screen!

1. Create a Private Game on NAVEZGANE with zombie spawns disabled and invite the person you plan on duplicating with.
2. Collect at least 1 vitamin most commonly found in Pop-N-Pills. One can be found in the city on the east side of the map (645 N 1150 E).
3. Craft 2 stone axes.
4. Collect some wood and create 5 secure storage chests. Use the duplication method below to duplicate any wood, extra secure storage chests, or axes you need.

Now for the duplication process:
1. Keep a chest somewhere to hold excess vitamins.
2. Host places 5 secure storage chests in a straight line and breaks the lock on each turning them into storage chests that your partner can open.
3. Host then stores up to 5 stacks or 250 vitamins total into a single chest, anymore than that and it may not work.
4. The 2nd player now takes each stack of the item inside the chest (Do not loot all (LS), only press RS on the individual items) and puts it in their inventory. Keep the menu open and let the host know to break the chest. Once destroying the chest a bag will pop out with the items copied. It will take approx. 750 or 15 stacks of vitamins for each player to get the achievement.
