Which a good attribute build for an assassin?

I would wait till after cr2 because they are capping the attributes at 30 and the only way you can get attributes from then pn is lvling. so if your stuff is at 30 or under 30 keep it that way, so you can get used to it.

You dont realy need points for assassin, ok so focus helps a tad but you can make Stealth, stealth damage etc up in clothes :smileyhappy:

wow dont listen to the post about cloths. After The CR2.0 cloths will be meaningless or almost atleast. You want to Put your attributes like this belief 10 %. Perception 40%, focus 40%, reason 5 % and vitality 5%. I think on redpill rescue there is a calculator made from a spreadsheet to help you calculate exactly what you should put in. Also I want to warn you that missioning with assassin/ spy is Extremely difficult. and you may want to also have a MA build ie: Karate or Kung Fu.

Yeah I agree... No matter which spy tree you choose you should add a pinch of MA as you'll definitely need it after a sneak attack.

I disagree with the hard to mission with assassin is hard, once you are high enough to get the disguise ability with some of assassin its actually quite ez (very hard with sneak because they see past it instantly and look at you lol), only thing you have to worry about is evade shields.
