3 Questions about the Assassin

[Silas North]

1. I have heard that Death Attack does not work unless you possess at least SOME sneak attack. Is this true in Sundren? ((If this question was asked and answered before, I apologize. I could not find anything))

2. Of the new skills (disguise, balance, etc.), which do the Assassins possess?

3. Do the assassins get the thieves cant language like the rogues, or is a rogue level required to get such?
