Little Warrior - Achievement / Trophy Guide
You can get the Chainmail in chapter 1. When you leave the room with the wizard, go up the ladder. Now go all the way to the right, to the altar, and step on the symbols in the right sequence. (Step back a little and look up at the stars to find the sequence.) This will unlock a grate. Go to the tower and go into the room where this grate is located. There you will find a wall with a big hand on it. The Chainmail is stuck in between the stones of that wall. Now keep pulling the Chainmail until it comes out. Before unlocking the grate the Chainmail is visible but it will not come out when you pull.
Little Monk - Achievement / Trophy Guide
After you get the sword (beginning chapter 7) you need to go back to the room where the wizard skeleton is located. So go back outside to the place where the deer is and go back down the ladder. There you will find the entrance to that room. Now pull the mask off the wizard's face.
Dark Knight - Achievement / Trophy Guide
You can get this in chapter 7. After you get the sword and chase the dragon away, go into the justice dream sequence that is located where the dragon was. Finish the sequence and when you come back out backtrack to the beginning where there is a deer (fastest way is to go down the steps across from where the dragon was). Now slash the deer with your sword (this wasn't possible before the dream sequence) and the deer will go to the altar. Slash it again to sacrifice it and you will get this achievement.
