Completing a perfect run of the gargoyle sword mini-game is aggravating at first, but there’s a very simple trick to guarantee you win. First, if you haven’t already, brew the Supersize spell (Amethyst + Eye + Blood) and equip it. Supersize the sword, grab it, and walk over to the gargoyle (It may help to move the sword over there first, before starting.) Stick the supersized sword in the gargoyles mouth, this should instantly slice ever apple he shoots. Wait until you reach the end and the skull announces you’ve completed a perfect run.
The easiest way to complete this achievement is to first, obtain the cylinder by fighting your way through the dungeon. Once you obtain the cylinder, return to the main area, grab it in your non-dominant hand and hold it upside down, activating slow motion, until you complete the achievement. Then grab the crossbow in your dominant hand and fire it at the target above the window. Shoot all the following targets that appear until the skull announces you’ve completed a masterful run.
Ooh a secret!
This achievement I truly recommend you find on your own by just playing around in the main area, but if you’ve truly given up…
You see the eye clock above the window at the front of the room. Shoot that with the crossbow, symbols corresponding to 4 certain xylophone keys appearing from left to right on the walls infront of the table. Play these keys in order and a portal will open up which will take you to a secret area. I’m not sure if the keys are the same for everyone, but they were as follows for me: A F C E
Note: When you get to the secret room, walk over to the hole in the wall to the left of you, there should be a golden ring, grab it and put it on your finger. It does magic stuff I guess.
