Caution: This guide is for people who know how to harass and play Well under different circumstances and know how to use Kass' abilities well. If your expecting a quick nuke guide to carry your team i suggest you scroll back up and look at those other random guides.

Playing as kassadin, you need to understand that your going to start out squishy and that even if you get fed or if you have all your items ready by mid to late game, your still pretty squishy but your burst damage will be Stupidly powerful and useful for your survival. But he's still an assassin so that means dont go initiate a fight when everyone is running back and forth at a turret trying to pop off hits at each other but too afraid to go fight another team fight because more than likely they have someone that can turret dive. You can stay in the middle or back and wait for an opportunity to get kills and you will need to do this Alot for your meij's.

Starting out, if you have a support character laning with you, Then this build is going to work quickly for you but you still need to play smart when harassing because if your with sona, she can help you get kills or finish off a champion kill for you and you still get stacks if you already have your soulstealer.

If your not laning with a support and you have a melee or ranged fighter or a mage, Don't get ballsy when someone is low because you've harassed them to 200 health. Depending on who is with that person, you may or may not get that kill. In the end it depends on the persons skill, lucky mis-clicks, and a good internet connection.

By mid game hopefully you will have a deathcap already and be doing some damage. You can go around and get gold off creep waves or jungle of your base and the opposing base if the other team is trying to fend off your waves or in the middle of fighting your teammates.

After you've gotten a blue buff, stick with your team and try to get assists or kills for your stacks and this will help you with your damage dealing until you've got both of your Archangel staffs. At this point your going to be nuking the **** out of the other team and you'll be a big help if you get a surprise attack on the opposing team while their fighting but just know that this build is for "in and out nuking". You may not always be able to stay in the fight and keep sending the damage through.

If this happens, you could decide on whatever you want to sell, and either buy a banshee's veil, zhonya's hourglass,zhonya's ring, or thornmail. it depends on who is dealing more damage to you and be observant to who is plowing in your face the next time you die so you can figure out what to use.

Feel free to give any advice useful and for the runes sorry if that doesnt look right my browser was being weird while i was making this and wasnt quite cooperating when i was choosing some of the items for this build so just leave a comment if you have a question about it and ill tell you what to try and use or do what ive been doing and do research. I've been playing a month now and it's not that hard to learn the game but getting good at different situations clearly takes skill that usually why when you play with level 30's with 300+ wins are usually carrying your team with almost any character from my experience with my friends.

Thanks for checking it out, im playing LoL everyday so you may see me on.
