Thanks to its long invincibility, the Superman dive serves as a useful emergency maneuver when all heck breaks loose.
A turbocharged version of the roll, you can initiate the dive by hitting the roll button while dashing with your weapon sheathed. It's a bird, it's a plane: So what's the second thing I teach beginners, you ask? That would be the Superman dive. Pressing the roll button while on a wall also lets you dash climb as well. Also note that you're invincible for fractions of a second at the start of your roll so use that to your advantage. If you're constantly getting mauled by monsters because you're waiting for your attack to naturally end in order to move without rolling, well, you're doing it wrong. See, in addition to dodging attacks, rolling is also a great way to cancel combos so you can reposition in a jiffy if you have to.
That, my friends, is what Will Ferrell's George Bush calls 'strategery.' So what was the first thing I taught them? Learn to roll, that's what.
And yes, that is suspiciously the same amount of people I need to form a full hunting party. Get rollin': I've personally introduced three people to Monster Hunter, who ended up being lifers of the game.
