Dose of his own medicine - Achievement / Trophy Guide
The first torturer is encountered in the first part of "Deliverance". Find the wooden well. The torturer will be on the stairs next to it, wearing a black robe and wielding a large knife. Duel him and win.
Great power... - Achievement / Trophy Guide
Regardless of difficulty setting, every secondary objectives must be completed and all insignias must be unlocked in order to gain enough experience points to unlock all skills.
Music Lover - Achievement / Trophy Guide
At the beginning of the game, during the intro "Reminiscences" 1/3, get your dagger, then pass the door. Climb onto the second platform, then look at the world tree and wait for two minutes for the song.
Unseen, unknown - Achievement / Trophy Guide
Save very often as you progress through the game undetected. If you get spotted, reload the last saved game. Note: If you do not have the Insignia of the Shadow after a few missions, return to them later through the "Replay Mission" menu at your hideout. Note: If attempting a 100% completion, consider doing all the Insignia attempts (stealth, no kill, no alert, speedrun) at the same time. You will need all insignia skill points as well as every objective to get enough points to purchase all the skills. It is easier to kill everything and collect all the tokens during your first run, then complete a full insignia run on the same level immediately following.
Like looking through a wall - Achievement / Trophy Guide
In order to do this achievement, you need to do the following: spawn a copy, make sure you have enough ember to use it's smoke bomb power, run into a group of 3 or more guards, use the clone's smoke bomb power. And the achievement is yours!
My precious - Achievement / Trophy Guide
You actually get this for collecting all 8 RELICS, not the 100+ "treasures" of the game. A little confusing.
