I don't like that at all with this game. Spoiler below:
Spoiler!
right off the bat you meet an 'assassin' who turned wannabe Templar. When you kill him you throw away the hidden blade because you don't know what it is, but if you go hunt an animal immediately you use the hidden blade. In chapter 2 you are then given hidden blades to prove your skills and magically you know how to be an assassin. TADA!
As a mega fan of the story and lore, so far I am disappoint.
What an idiot throwing that away. If nothing else he could've put it on ebay. I'm sure people here would've shown an interest.
