if you are having trouble agianst magic then get the veil instead of the frozen heart or the guardian angle.try not to get focused allot as if you do you will be useless so play defence when need to and go agresive when the enemy is least expecting it.

I suggest if you are using this guide then dont be too agresive in lane before level 7 as you wont have that much damage output but once you reach level 7 then you should be able to rack up alot of gold and kills by going through his basic damage combo. use this in order: cut throught, nox deplomacy, rake, ult. (e,q,w,r) this will get you your most damage output and would enable you to get many kill just by using 1 combo. as an assassin you need to judge your enemy movement and damage output. killing somebody with too much health will probably get you killed for no benifit .

this build is a very effective build if used correctly. this build gives you some defence bonus to stay in team fights for longer but you still wont be able to take much damage so try to not get focused allot with this build. Another bad thing about this build is that it is not as elective on tanks as i would like. you could probably get a tank down to about half health with the combo but since talon needs he ability to do damage you would need to wait for cool-down but by that time the tank would of killed you. try to take out the enemy dps threat so your team would have an advantage in team fights but use your ult to get away from people if need to so don't always waste your ult to get a kill.
