Malus:

• So the general idea is that you have to follow the path you see in the video (you don't have to whistle/change weapon, unless stated, it's something I do for getting a little more speed), I'll point out a few things you have to keep in mind while doing this: 0:07 make sure malus' magic-ball hits the pillar; 0:13 that jump is NOT a long jump, you can figure out how much you have to hold the jump button on your own (it's very short, sometimes even just a hop depending on your timing); after the jump whistle/change weapon so you're not slowed down; 0:17 I make that jump when I get to that patch of green grass, it more or less coincides with the magic-ball hitting the ground, and it's a SHORT jump, just tap the jump button; 0:18 When you land immediately change weapon, tap the jump button and fall pressing R1 or R2 (the grab button). If you do it with the right timing Wander will hold onto the ground exactly when Malus' magic hits, and you will come out unscathed. After that it's pretty clear what to do :D
