Investigations are a type of free-roam Quest in Monster Hunter World (MHW). Players will take on these activities to advance their characters and gather useful materials.
How it works
Killing, capturing, breaking monster parts and investigating monster traces have a random chance to grant an also random investigation.
Killing small monsters gives a slaying investigation related to this specific species.
The large monster investigations however are unpredictable, even though it seems to be related to the monsters threat level. There are 3 threat levels and you unlock investigations of the same level as what triggered it.
Example: Investigating a Barroth (threat level 1) footprint will give a threat level 1 investigation. If the Barroth is tempered then the investigation will be too.
Threat Level 1
- Great Jagras*
- Great Girros*
- (Master Rank)Pink Rathian
- Coral Pukei-Pukei
- Viper Tobi-Kadachi
- Nightshade Paolumu
* = Can't be tempered
Threat Level 2
- Azure Rathalos
- (High Rank)Pink Rathian
- Black Diablos
- Yian Garuga*
- Shrieking Legiana
- Ebony Odogaron
- Acidic Glavenus
- Brute Tigrex
- Fulgur Anjanath
- Scarred Yian Garuga(Can only be tempered)
* = Can't be tempered
Each investigation has a random number of attempts and has random conditions:
- Time limit: 15(High Rank), 20(Master Rank), 30(High Rank), 35(Master Rank), 50 minutes
- Faint limit: 1 to 5 allowed
- Max player limit: 2 or 4 players
- Objective: Hunt or Capture(Elder Dragon and small monster investigations are always gonna be Slay investigations)
The zenny reward is based on the targets species and number and can randomly be doubled. You can use a daily voucher to double the zenny reward again.
In addition, each investigation has a number of bonus reward slots, colored in bronze, silver or gold. The number of bonus slots seems to be random, ranging from 2 to 5. But there is a correlation between the quests conditions and the slots color, harsher conditions generally means more gold slots. The slots color seems to indicate different drop rate, but not a different loot table (i.e: a gem can drop in a bronze slot, but is more likely to drop in a gold one)
High rank investigations, like other quests, have a high probability to have decorations as quest reward.
After completing the Land of Convergence quest, investigations can have Tempered targets. Tempered investigations rewards the player with decorations in each bonus reward slot (purple), often Streamstone Shard/Streamstone/Gleaming Streamstone (respectively from threat level 1 / 2 / 3 investigations) and very rarely augment materials as quest reward. In Master Rank, tempered investigations will only award decorations since augment materials are obtained from Guiding Lands.
Tips & Notes
Threat Level 2 Tempered Investigations Farming Method
If you get a Tempered Bazelgeuse investigation (Elder's Recess), you can use it to farm other Threat Level 2 tempered investigations easily. Take skills enhancing your movement and stamina, you are going to run/climb a lot but not fight.
The Bazelgeuse should spawn in its nest in sector 4, so start from Eastern Camp (8) and climb all the way up to get 4-5 investigation points.
Then follow this direction : Sector 4 > 9 > fast-travel to Southern Camp (1) > 7 > fast-travel to Eastern Camp (8) > 4 > 9 > ...
Look at your map to understand the Bazelgeuse pathing and where to look for footprints/scales. It should always leave the sector as soon as you enter it, just be sure to not engage it so it can refresh the footprints.
The Bazelgeuse will sometimes need to eat and go in Sector 11 or sleep in sector 4, just wait for it to leave, get the investigations points and go back to the usual pathing.
I was getting an average of 1 investigation per cycle, which is more than 20 in 50 minutes.
Likewise, if you get a Tempered Diablos or Black Diablos investigation, you can use them to farm other Threat Level 2 tempered investigations. At this point, you want to go into the cave where they can be found, and wait, every 5 to 10 minutes or so, they will leave the cave to eat, and it is at this time where you can walk around and grab all the footprints they leave behind. You will easily farm multiple investigations (around 2 or 3 per round of pickups, although can be higher or lower depending on your luck) per quest.
