MONSTER HUNTER: WORLD

Update 4/7/18:

To get this achievement your going to need to get ready for a grind and a pure RNG grind at that. (PS Deviljo does not seem to count for these achievements so I'm guess that it's just the base game monsters (see images below) that you need the crowns for. Your going to want to be picking up all the footprints while your playing the game and delete all the investigations that dont have at least 1 silver / 1 gold in them. I had 0 luck getting any large or mini without at least 1 S/1G. (you can have any other combo as long as there are 1 s and 1 gold)

At the time of this solutions there are 5 weekly quests that rotate, there are some weeks that have every event quest active so pay attention for those (you can view the rotations here: http://www.monsterhunterworld.com/us/eventquest/) that you want to be looking for. These quests have a much higher chance to give you crowns since there are multiple monsters in each quest (keep this in mind for further investigations). I would suggest that you wait for the events for these unless your the monster is your last one. This is the best way of getting the crowns for these monsters, don't forget you can load up the quest kill the monster you need the crown for and leave without finishing the quest, the crown will still count!

Deep Green Blues ( Ancient forest) - Great Jagras / Pukei - Pukei / Tobi - Kadachi / Anjanath / Rathalos

Wildspire Bolero ( WildSpire Waste) - Barroth / Jyuratodus / Rathian / Diablos / Kulu - Ya- Ku

Coral Waltz (Coral Highlands) - Tzitzi - Ya - Ku / Paolumu / Legiana / Pink Rathian

Effluvial Opera (Rotten Vale) - Great Girros / Radobaan / Odogaron / Bazelgeuse

Rock N' Roll Recess (Elders Recess) - Dodogama / Uragaan / Lavasioth / Azure Rathalos

I wouldn't worry about finding these with investigations as the event quests are much easier and you can knock out multiple monsters at once.

Now were down to working with the rest of the monsters. The best way to do this is look for investigations that give you 15 mins for mini and 50 mins for Large crowns. It's best to look for investigations that have 1-2 faints as well as they usually have better luck but the time seems to be a big factor. There are thousands of webpages that post the different specific investigations that you need for crowns. IGNORE ALL THESE. Crowns are pure RNG and if someone else got it, it doesn't meant your gonna get it. Focus on the times. If you find a 1 faint / 15 min / silver silver gold gold you will most likely get a mini crown. While your looking through the investigations if you can find one that has multiple monsters in the same one with a different time/faint then make sure you test these out. Most likely this will change the monster sizes.

There is a post on TA about crafting max potions and the such to try and change the monster sizes to your liking. To me this method never worked and just wasted time. If you want to do this method it's best with another person so that you can lower the monster, they join and disconnect from the internet and finish the monster on their own to see if the monster is a crown. if it's not then you abandoned the quest and do the method to make it larger. Again I didn't use this method as it felt really a waste of time.

I would really suggest trying to find a group of players that are all searching for crowns as this makes it go way faster as more people are searching for each monster (especially Kirin).

There are many videos online showing the videos of how to measure monsters. The thing I will suggest is to just go in and find how the monsters look for you. After 2-3 fights you should know the "normal" size of monsters. Usually with most monsters when you see a mini your gonna know it's a mini, it just doesn't look right with how small it is. The same goes for Large. when you see a large your gonna say to your self, "wow that thing is huge".

When you want to check what crowns you have or sizes the best way is to hit Start -> Tab to Info tab -> Guild Card -> View -> LB and that should show you everthing. This is much easier and cleaner than looking in your hunters notes.

When you get the crown it will show up in your rewards screen like so:



Here are all the sizes for the crowns by yours truely:









I hope this helps and welcome to the grind :)

You will get this achievements in the process:

Miniature Crown Master - Obtain a miniature crown for almost every monster in your hunting log.

Hey everyone, Krauser here with a bit of info regarding this. Im gonna be breaking this down as simply as possible so that almost anyone will get the jist of these horror achievements. This one here is to have all "Changable" monsters for size (see bottom of the post) at its biggest or smallest form. In this case smallest.

Quick Note - Im from now on putting all "Updates" up here from now on seeing as we're caught up on the sizes, and the guide will follow below for those of you who want to check in on special events. Im also adding a spoiler right under this, and that will be the size comparison sheet.



IMPORTANT UPDATES:

CRITICAL UPDATE 02/23/2018 Below this i've added a spoiler of the rumored DLC release schedual. If this is true, we are unsure if this will extend the crowns required! I suggest you farm as quickly as possible!



02/22/18 "Deep Green Blues" is over, however, a new quest called "Wildspire Bolero" is present awarding tons of decorations and the Kings are slowly filtering in for: Kulu-Ya-Ku, Barroth, Jyuratodus, Rathian and Diablos

02/17/18 As you can see (and reported by a couple others) by the screenshot below, the current event quest titled "Deep Green Blues" involves killing a Great Jagras, a Pukei-Pukei, a Tobi-Kadachi, an Anjanath, and a Rathalos all in 50 Minutes. This is a High Rank Quest as well and took about 20 minutes. People and myself are reporting high luck getting King Sizes both big or small. The screenshot down below is from my hunt where they all spawned together. This even is running as of the update date above for 5 more days. I suggest you guys give it a shot. Also, Proof of Gold Crowns in the picture for those getting frustrated with only seeing silver crowns and all that.



Other Updates:

02/22/18 I will no longer be updating the numbers in the spoiler. We now have a compiled list, yes there may be some variances, however I am also condensing this guide and updating it as there are new ways to handle farming these guys. I appreciate and love you all for the submissions and numbers to compile this list, and glad we got where we needed to! All credit has been provided. Best of luck hunters!


GUIDE


Most monsters save for a few in Monster Hunter World will vary in size, meaning that if you fight for example a Rathalos once, then again right after (even the same quest) then it could be much larger or smaller.

This right here has a cap limit on how big or small a creature can get. Silvers (or queen's as I may refer them) and Golds (King's) Crowns will be next to the size. Silver meaning you're getting close, gold meaning you're within a range. Typically these Gold sizes are a 25% (or more) difference to the normal monsters size, however, you can get bigger or smaller gold crowns as well, so to dispell any confusion, youre not going for the smallest or largest possible, but a rather large or small variant past a certain threshold. Refer to the spoiler above for indication.

So how do you get these to spawn?

Well... You don't. It's pure RNG. HOWEVER, most people will churn through the quests and optionals but DO NOT FARM OPTIONALS for materials, sizes etc. Do investigations (better rewards) if possible.

I want to stress, do this as your final achievements while focusing on others. These can spawn in any quest, arena, while you're farming gear etc.

It has been confirmed that weekly events such as "Deep Green Blues" and seemingly any future events that have 5 Monsters to hunt may yield much higher chances at these variants. If you look at the important update above you can see I got it myself. I will be updating the weeklies as much as possible with either personal experience or more comments.

People seem to think that 1 Silver and 1 Gold reward investigations have higher chances, that 15 minute time limits are smaller creatures and 5 faint 50 minutes are largers. This is hard to prove as it is again RNG... But here comes the fun part... There is technically a way to farm these efficiently.

In my previous guide, I mentioned walking in and sizing it up, quitting and doing it again, this is being referenced as Crown Sniping.

Thanks to Fuzzmeister J who stumbled upon this wiki thread: https://www.reddit.com/r/MonsterHunterWorld/comments/7z5o70/...

For those who want to see the pictures of the amazing Nick6818's list, or his detailed breakdown, check that out. If you just want quick notes on it, ill paraphrase:

Step 1: Make a ton of shocktraps
Step 2: Put on Ghillie Mantle
Step 3: When you see the wyvern, put on Ghillie, Sneak up, and put the shock trap down
Step 4: See how big you are compared to a point on the body IE The leg, or a specific point
Step 5: Either Return from Quest, or Kill then Return from Quest
WARNING: DO NOT ABANDON QUEST, IT WILL NOT WORK AND CANCEL ALL YOU'VE DONE, MAKE SURE YOU USE RETURN FROM QUEST IF THE QUEST ISN'T OVER AND THE CREATURE IS DEAD OR CAPTURED
Step 6: Eventual Profit

I used this method (without the shock and ghillie) to farm the weekly pukei and Returning did in fact count my gold crown. Capturing or Killing doesen't matter in terms of the Gold Sizes counting.

A few things to remember, you can't trap elder dragons, however, if you hide from them they will sit occassionally (thanks again to Nick). Farming with friends makes it funner and easier. Do the 5 kill event quests (apparently there's a rotation). And last but not least, if you join an SOS or quest and can't get rewards, doesen't matter, if it's a King, itll register for you.

Happy Hunting!
