Having played an assassin, I would say an assassin should beat the thief at any given time. You need one prep to nullify the biggest weapon in their arsenal. On top of that, assassins have a weapon thieves don't, use it. For extra cream, maledictions.

There you have it. The times I did hunt for you though, I didn't intend to call in aid as I knew I had a decent chance of beating you on my own by doing one of the things mentioned above.

Oh well, keep on trucking, scion has it rough.
