Waving at the Dragonseer Ballons reveals the Monsters locations
In every Monster Hunter game, if you look into the sky there’s a random chance that you’ll spot a Dragonseer balloon. It turns out that they’re not just there for decoration because if you use the Wave gesture while looking at it, it will briefly reveal the location of whatever monsters are in the surrounding area.
This can only be done once but this is still extremely useful because there’s nothing more annoying in these games than spending 20-minutes running around looking for the damn monster.
Another time-saving tip specific to MH4U is that you can actually skip the camera shot of the monsters death animations at the end of each hunt by using the skip option on the bottom screen. While this option is usually used to skip the cooking animation, this can be incredibly useful after hunting monsters with long death animations such as the Dah’ren Mohran.
