When it comes to armors, Assassin wears leather, period. You can wear cloth armors but you should never ever wear them because it is useless for an Assassin. Since Assassins are an evasive class, they rely on their evasion, and so leather armors are the only armor that have the most bonus points on evasion. Sometimes an Assassin with high evasion build can become the tank for the group; since their evasion is so high that only a few attacks would actually land on them. However, if there is a tank in the group, let them do their job and you focus on doing damage.
The Assassin has the ability to use 3 different types of weapons: Daggers, Swords, and Bows. However it is really more like two different types of weapons, because you're not really going to use a Bow as your primary weapon for PVP or PVE.
For people who have more experience with MMORPGs gameplay, you are probably thinking that "Assassin uses daggers as primary, and swords as maybe an offhand weapon" and that is exactly what I thought when I played Assassin in Aion the first time. In every other MMORPG I have played which has a class like Rogue, Assassin, or Thief, their primary weapons of choice are daggers, and then they might use a sword offhand for damage.
