As I acknowledge, monsters in World can flinch and even break part of others by their attack. Since monster attacks logically fall into "bludgeoning damage" because they slam each other for most of the time, I suspect they are always bludgeoning.
Well, are they? Glavenus, for example, has a blade at its tail, and Velkhana pierces with its sharp tail. Nergigante fires spikes from an impact point. Do they also count as bludgeoning, no exception? Is there a bullet damage among monsters? Are breath weapons by, for example, Rathalos, treated as bullet damage?
Also, is there a possibility that the subject damage is actually equivalent to explosions, like Gunlances, cluster ammo, or cannons?
