Going to the canteen to eat before embarking on a quest is standard procedure, and different combinations of ingredients give you different buffs and skills. Most of them are self-explanatory and usually buff yourself in some way, but there's one that the game doesn't explain very well: Felyne Weakener.
The ingame description is:
Increases the likelihood of large monsters encountered in Quests being weak.
But it doesn't go into any further detail.
What does "weak" mean in this context? What is the "increased likelihood"? If multiple players activate Felyne Weakener, does it increase the chance further?
