Two questions about Talisman

By beyond_zork, in Talisman Rules Questions

Hey guys, just got this board game and played a couple of times with friends - we had a difference of opinion:

1 - when playing an assassin, and having the runesword, can i use the assassinantion ability to drain a life?

2 - when playing a thief - if i get attacked and lose a fight, and the opponent decides to take one of my items, can i then steal it back? or should i steal one from him before the fight? or am i able to steal at all when attacked?

Thanks in advance for any clarification.

1. Yes, you can.

2. No, you can only steal items from a character that YOU land on. And if you steal something you cannot engage in combat afterwards. It's one thing or the other.
