Every role has a job to do in a team fight. For the ap carry, its kill the enemy squishies. Many times in a team fight your allies will get stuckk focusing the tank. This is not ideal, but you can work with it if you have to. The ap carry is solely designed to get past the tank and kill the enemy ap carry, support and ad carry. If you are super fed then you can probably do this alone. If not, try and make an opening for your tesm to jump onto the enemy squishies. This can be achieved in a number of ways.
Here is a list of each mainstream ap carry and their main ways to get to squishies with your team.
: Unless the enemy team has oracles or a pink ward, just jump at the squishies, chuck your shroud down and feast.
: Anivia takes some skill to initiate with. You can either lob a q over at the squshies, because a sloow and stun are great ways to isolate the squshies. Or, if you feel up to it, you could go for a clutch wall and split the enemy team so that your team can easily pick of half at a time.
: Build your stun up, then either run at/flash at the enemy squishies (after telling your team you are going to) and tibberf*** them. The aoe stun is more than enough to get your team in on the action.
: I dont play brand much, but in most cases, you can just lob your pillar of flames at the enemy (yes i know that lob doesnt really apply to this spell but you get the point) If you land it then you can do a lot of damages, and then try land a q on them. Or you could flash closer and mash all the buttons at once and click someone.
: You can either stun the enemy tanks and your team can walk past them for easy kills, or set yourself up with flash or good positioning to stun the enemy squishies. Either one will be a good move. That or you could slow them with miasma.
: not really a mainstream ap carry but it can work. However if you need ot be told how to intiate as cho i dont think you should be playing him...
: AP galio is great at this part. Flash and ult and watxh your team and your ult decimate them.
: This guy seems to be an easy question. However, positioning the ult is quite hard. I recommend using your bodyslam and/or flash to get close enough to bomd just behind or between the squshies, knocking them away from their allies or into the fight.
: Karma isn't as strong an ap champ as many others, but it can be done, and her passive gives a low health karma a surprising punch. Explosive shield your tank or initiator for the damage, or use the shield on a carry for defense, and try line up your slow through as many enemies as possible. Hold off on your q until you can mantra q for a heal for your whole team.
: The equivalent of a suicide bomber. Chuck your wall down toggle on e and run at them, if you die just keep hitting them and ult before your passive wears off.
: just trololol them. jump in use q and e, jump out, jump in and q again. If they get frustrated enought o chase you your doing your job and your team can kill the rest of them.
: Wait for the cc to get used if possible, thjen shunpo/flash to the squshies and ult.
: Flash in and ult, then zhonya if possible.
: jump over to them, q then r then e then ignite and then press w again to jump out. You should decimate one of the squishies.
: Land your snare and e, and then ult if u feel its necessary. Your team should go in with the snare.
: Put your pool down in the area the enemy is fighting in if it is confined. This forces them to move out of it or take a lot of damage. If they are out in the open, try to harass the enemy down with your malefic visions and silence, and when their cc is down, pool under someone and ultimate them. This gives your team a large opening.
: Throw your saplings everywhere in the fight, and try isolate an enemy squishy with your snare. Put your ultimate down around yourself when you reach the target and your team should follow.
: I refuse to acknowledge this guy as an ap carry. Not a real issue, but my opinion is he doesnt fill the role as well as many other champs.
: TROLOLOLOLOLOLZ flash into themiddle of the enemy team with your spell shield on, put your pool down, start your ult then zhonya if you have it.
: Generally its easiest if one of your tanks inititiates and you shield them and then use your ultimate to disrupt the enemy team. Otherwise, you can use command:attack to move the ball into the enemy team then command:dissonance and then command:shockwave
: Use your ultimate down the middle of the team and try split them with it.
:snare anyone that overextends, tanks included, and then as the team rushes forward to help swap focus to the squishies and try burst them down.
: Try and land your nevermore, or if you are tanky enough just use your ult and run at them. Slow someone with laser bird and do as much damagge as you can.
: Try and use a quick gold card on an overextended enemy and burst them with your wild cards.
: Put your event horizon down in the teamfight and stun everyone or as much as you can.
: Run in and use your transfuse, tides of blood and ult then pool and watch your team shred the enemy. Also, it is advantageous to have your tides of blood at max stacks when initiating this way as it adds a lot of damage.
: I don't play xerath very much, but the basic aim as xerath is to sit as far away as possible from the fight but stay in range, and then try to stun a squishy, and nuke them with your ultimate. If you can take out an enemy champion before the battle even fully starts then your team will have a definite advantage.
: Double time bomb the closest person, speed up your ranged ad or tank and be ready to ultimate whoever is targeted.
Ok bare in mind that these are situational tactics, and that they are also my opinion. I do not play all of these champs all the time, but i have played them all at some point. Feel free to use any of these tactics or disregard them as you please.
Also you may argue about a few ap champs i left out, but i dont think i missed any major ones, and if i missed some minor champs please let me know :)
