Everyday when i come to this site i c the same Q everytime..
What is the best build?
Int need wep skills?
OK..
There is no best build in this game i hope u all get it by now!
If there was a best build why dont we all get it and stop waste time on the bad ones..End of that story.
Now for the Q about sword skills at Int S/S
1.The passive raise ur BR its very good becuase just that block can save ur life
2.Light chain..This is the best skill for a S/S nuker..Get the stats on ur enemy and after that make a nuke and u will c that ur nuke gonna HURT so bad on the one u wanna dmg

and if he survie that fast make a KD and try get stab + stab after eachother whit imbue and almost 80% of ur challangers is dead...Depends on gear ofcourse.
3.Imbue..
This is very important when u use wep skills...Whitout it ur wep skills gonna sux...but whit it u hit as hard as a pure str or more..
4.So..
What we get in our heads now?
use lightchain and try to fix the 3 stats at ur enemy and after that nuke and WOW ur nuke hits 2-3k more dmg..
Passive..BR increase good for tanking when ur block chances is higher..
Wep skills is as good as a pure str when u use imbue..
So if ur a pure int ur like the best from 2 worlds but whit low Hp...
