I will personally go with TBS Silence XG + CCC XG. The Silence set only gives a bonus of Damage +20, Attack Speed +15 and Moving Speed +20. The Hat of Silence XG doesn't offer any Offensive stat bonus, it just gives Damage Decrease of 9% (No Refine rate yet-base stat). However, the CCC XG (no refine), gives +9% Damage Increase which is important if you want your Assassin to Hit Hard. Now, if you can afford it, go get the Murim Assassin Chakram XG from the Item Mall. It gives a good amount of Damage. then just get a pet and some accessory that Adds % Damage and you're good to go. My pet gives an additional 2% damage, I also has a good accessory for that as well.
