For those having a problem beating Vanguy in HARD mode.
1) At the first 3 ticks of health, Vanguy will walk slowly... Slow and irritating, as his blade has a longer reach than yours. However, the lone warrior's attacks are faster than Van's ones, the trick of the main 3 ticks is to simply run toward him and attack a moment before he does it. Spam auto-attack until his health goes down and he gets "Serious".
2) Here, the roles are inverted... The trick is to stand still and let -HIM- run to you. Don't move, running and turning back to fight him won't make your strikes fast enough to get him. But if you stand still, you will be able to hit him right before he does. Note, when he begins to teleport around and about to knock you in the air, he will always appear infront of you. Good thing that you were standing still and meanwhile you have the time to place yourself behind him, go to the toilet, eat a snack, and when the animation is done smack his face with the usual combo. Good Luck!
Defeating the final boss for those having a problem or two (or three....)
Step 1) Max your sword... Forget about the armor and the magic, go straight for the sword, when you get to the boss, you should have a lv 6-7 (or if you grind hard) 8 weapon that's gonna spare you a lot of troubles.
2) Balls of fire... Lots of them, the key is standing still and JUMPING, jump a lot to see them coming, simply run head-deep into the fireball coming next to you, with appropriate timing you can get in the same spot where the ball landed without turning into a flambè knight. Repeat for the second ball.
3) Climb the stairs and get to the "demon". Repeat the dodge-trick I explained in part 2. Done
4) At this point the demon is easy as slicing a pizza (which may result difficult with an unproper knife ... - Reason to upgrade your rusty sword - ), just stand where you are and bash the demon's face everytime it flies toward you. (There wasn't enough space to make the miniguide longer, Enjoy!)
