Recently, I had a decent game (on SR) as the hat man 
with this build: 
, 
, 
, 
, 
, and 
. It was only until after the game that I noticed that I did not have 
but I could still two-shot everyone on the enemy team when 's active was up.
Are there any situations where you shouldn't/wouldn't buy ? What would you have dropped in the above build to make room for ?
The match stats are included.
I Main Swain2 votesno, rabadsons is actually very often outpicked by many other items by a lot of champions. for example, for swain, I will under no circumstances get a in my build. it can also be outpicked by magic pen items like 
etc, since they all (but ) give some decent magic pen, ap, and defensive stats like health or mr. rabadons is never something that you always want, its just a good item if you want a buttload of bonus ap, like 
soulstealer. I would very seldom "always" get an item, just leave it mostly for situational and for what your team needs most from you.
hope that helped :D
TheOrgansolofan1 votesLooking back now I see that they did not have much in the way of MR, so I did not need a bunch of AP anyways. Thanks!
I Main Swain1 voteslots of ap is actually the way to go if they have little mr. just need maybe 1 pen item if they have extremely little, 2 if they have just a small-ish amound.
I have recently gotten very into getting survivacarry items like 
stuff like that that gives defensive and offensive stats. sry if im being annoying with my posts this is just my big thing.
Rhyto1 votesYou wouldn't really need the D cap unless if your fed hard early game because items like what firedancer2000 suggested are usually bought because they are cheap and have decent stats to work with your champion.
I Main Swain1 votesnot necessarily. it depends on a lot of things, mostly what champs there are. if you are playing someone like 
then DFG would be a great pick, because it works well with her new Charm and, unless she is ridiculously fed, she lacks the necessary burst to 100 to 0 them with 1 of each ability unless she uses her ult. it also depends on the enemy comp and if they have a lot of mr. its a great item against tanks or people you know have to be gone from teamfights before they can contribute anything.
Rhyto1 votesI haven't played Ahri quite alot lately, thanks for the info on the new charm friend. ^^
I Main Swain1 votesjust so you know, basically they nerfed her w dmg, reworked her passive heal to be a set heal for each unit hit with a spell, nerfed her w damage and made it so her e increases damage dealt to the charmed unit.
basically, now you have to hit Charm for her to have very significant damage.
Rhyto1 votesTalk about pressure :o
I Main Swain1 voteslol seriously. that's why you don't see her nearly as much.
Gondlink1 votesi woulda drop void staff unless they have quite a bit of mr
I Main Swain3 votesactually, natural mr can go a surprisingly long way, and you would be shocked to see how much extra dmg you do when you get a little magic pen for that natural mr. although, depending on their team, it may be better to get something with more of a mix of survivability and dmg that gives magic pen if you are going for that.
Roaranor1 votesRabadon's is quite simply raw Ability Power. Nothing more, nothing less. Keeping this in mind, the only time you should build this is when you don't need any other stats/perks other than raw damage and/or won't for awhile.
As for the above build, Void Staff and Magic pen boots are what shredded through the small amount of mr that the enemy team did have, bringing you pretty close to true damage. Lich Bane is core. I don't know that both Zhonya's and GA were necessary, but if that was the case then more power to ya'. If you didn't actually need them both, then I would've dropped one or DFG(late-game). I'll explain why.
While DFG pretty much guarantees you a kill on one specific target (which is really important in lane and for roaming), Rabadon's 120% AP bonus synergizes really well with the Lich Bane passive and gives you a higher damage output to multiple targets throughout a team fight.
This is, of course, just my preference. Either way, your build accomplished the job that it was supposed to, which makes it A-okay,
