This one is especially useful for those that favour weapons with the sleep element, though it's also useful for anyone that likes to end their hunts with a bang. Sleeping monsters take three times more damage on the first attack they receive. A fun way to take advantage of this is to set up an elaborate of array of bombs around the dozing beast, set them off with a barrel bomb S and viola - monster fireworks! Here's another small tip: if you eat to unlock the Felyne Pyro ability before a quest, every Barrel Bomb L in your possession will become a Barrel Bomb L+.
