In "Monster Hunter: Wilderness", the investigation of the Black Erosion Dragon is a survey task in the game. Fortunately, the feasibility of the investigation task of the Black Erosion Dragon is not difficult. You can adjust the time to any time period in the wilderness period when resting in the tents of the base camps in major regions (note: the probability of not specifying the time is lower) to increase the refresh rate of the Black Erosion Dragon.
How to check the Monster Hunter's Wilderness War Black Erosion Dragon's quest
Remove the junction peaks and keels that cannot rest. The time can be adjusted to any time during the wilderness period when resting in the tents of the base camp in major regions (note: the probability of not specifying the time will be lower) to increase the refresh rate of the Black Erosion Dragon.
Probability ranking is as follows: 1. Shayuan>Ice Valley>>Yongyou Valley and Forest
(ps: In Yongyou Valley and forests, you can adjust the time to dusk or at night during the abundance period. This way, you can also make a black-eroded dragon, but it is likely not a battle)
In the base camp tent in Shayuan, it is highly likely that it will appear in the morning/day/dung/night of the wilderness period, and most of it will be in the battle of the black erosion dragon. The same goes for Ice Mist Cliff, but the probability of going on a battle is smaller than that of Shayuan, but the difference is not much.
Reminder: Black Erosion Dragon only appears in Ice Mist Cliff or Dragon Valley
