I discovered this while battling the viciuose queen.
1.Rapid Jab-the queen does this when a wall is separating the main character and the queen.the queen uses its claws to hit the wall, because of the walls hardness, the queen will hit the wall rapidly while moving towards you thus destroying the wall instantly.i request you to stay away if the queen does this even though you are blocked by the wall.
2.Retreat Thrust-the queen does this if you attack it instantly if it appears.the queen falls back and then swipes you in an X form cut.stay away and dont attack it too much.
3.Larvae Repulsion-the queen does this if you hit it many times while it defends itself.the queen will keep producing larvae(tiny bugs not the worms).its too dangerous to come close and step on them cuz the queen usually protects them.i suggest that you lure the queen out of reach so you can step on its larvae.
