About Me
Hello, I'm H4xDefender, an average 1300-1400 player who watches a lot of online/offline league of legends tournaments as well as pro streams. I was a competitive player of some renown in some other games, but thats not important. I made this guide because I felt that I didn't really see many good (if there are any good ones at all) singed guides on this site. I have two builds up, one for solo top and one for jungling.
Singed - Trolling With A Purpose
Singed is a menace of a champion. He is the master of kiting, yet killing you while at it. Hes a great solo queue champion for annoying the **** out of people, and he fits in a good amount of team comps due to his tankiness and utility he brings to the table with his fling, and his powerful slow. He can farm like no another champion can, simply running through minion waves with poison on will drop them quickly, racking you up gold. Singed has been seen in low ELO to tournament play (mainly from Dyrus although The Rain Man has played him) as he is an easy champion to learn and very effective when used correctly.
Generally Singed is played top lane, but is a strong jungler as well with lots of AoE coming from 
Poison Trail as well as strong CC for ganks from 
Mega Adhesive and 
Fling. Singed does alright mid lane vs some AP champions, mainly ones that cant do much damage to him early on until he gets his 
Catalyst the Protector which gives him tons of HP and sustain, as well as mana to harass enemy champions mid. I feel singed is not good in a support role the way that some tank champions like 
Leona might, as prior to popular belief, he is not tanky earlygame.
Just for clarification, the first build is the solo top build, second is the jungle build.
The Abilities and Basics Of Singed
If you are new to the game or even a longtime player ask yourself: Do you want a champion that takes damage by the truckloads and still delivers kills? Do you want a champion that has an innate trolling ability? How about one of the best escapes in the game too? You can find all of these in Singed, The Mad Chemist, and in this build I'll show how to make him the most effective trolling monster there is out there.
Empowered Bulwark (Passive)
Pretty simple stuff, every 4 mana gives you 1 hp, which is why items like Rod of Ages that give mana, hp, and AP are so stronk on singed.
Poison Trail (Q)
Singed's main damage skill. This leaves a trail of AoE poison behind you when toggled on, damaging enemies caught in it over time. Toggle this on and run through minion waves to farm quickly, but beware this will push a lane very quickly. When being chased and when ganking or in teamfights, make sure this is on, it can make the difference between a kill and someone escaping with 50 hp. Just make sure you turn it off when not trying to push a lane or harass/fight. Max this first most of the time.
Mega Adhesive (W)
One of the most powerful slows in the game, it leaves an AoE piss puddle wherever it is aimed, and it is a humongous slow that only gets stronger with levels. Champions like 
Gangplank or 
Garen with slow removes will be slowed even through 
Remove Scurvy and 
Judgment respectively because the slow is an AoE that does not disappear immediately. When initiating ganks, drop this slow then go in with 
Insanity Potion and or 
Ghost to try to get a Fling down with Poison Trail trailing behind you. In teamfights, use this to separate teams to get an initation Fling down. Max this second.
Fling (E)
The famous trolling skill of singed. This is a knockup that actually knocks the target champion behind you. It is pretty straightforward. Make sure you do not try to last hit champions with this because you may actually end up saving them, and always make sure you fling enemies behind you, instead of flinging them in front of you which can aid their escape. When teamfighting as the initiator, do NOT fling tanks because they are the closest, ESPECIALLY if they have heavy CC. I cannot stress this enough as you may easily lose your team a teamfight this way by getting a tank free access to CC your carries. Take 1 point at level 1 and max this last. It is used mainly for positioning, not damage.
Insanity Potion (Ultimate) (R)
Singed's ultimate synergizes nicely with the rest of his kit. Use this to start ganks, initiate, chase, or run. It is not a strong ultimate damagewise, but it is very good utility wise, granting a large array of stats, including CC reduction and movement speed. Take points in this whenever possible. It is on a pretty low cooldown so don't hesitate to use it.
Masteries
I like to run a 1-21-8 mastery setup, the 1 point in offense for the buff to ghost, a standard 21 mastery in defensive, and 8 in utility for that nice movement speed boost. Pretty standard stuff. With movespeed quints, the
Initiator
and
Swiftness
masteries, singed gains a 9.5% MS boost, which is huge coupled with the MS boost from FoN, Insanity Potion, and ghost. There aren't too many other mastery possibilities on singed, 0-30-0 or 9-21-0 or even 21-9-0 if you are going for more of an AP damaging build but 1-21-8 are the most standard.
Items
A strength of Singed is his versatility. Depending on the champions that he is laning against, champions that are fed, and his role and position on his team, singed can change his build around and can be very strong it as well. Many items, from AP damage 
Archangel's Staff to sheer tankyness, 
Frozen Heart work fine on him. The recommended items are the most standard build to follow as it gives balanced resists to magical and physical damage, as well as enough damage to divert attention from carries and clean up kills.
Some other viable items on singed include:
Will of the Ancients: Decent for jungling, good synergy if you have an AP mid as well as top.
Thornmail: Cheap armor and lots of it. Counters 
Tryndamere. and AD 
Master Yi, well but frozen heart is for the most part better for the job for ranged ad carries like 
Graves
Banshee's Veil: Good for protection and absorbing nukes. Provides good HP, giving mana and hp, as well as MR but 
Force of Nature is better for tanking through sustained magic damage.
Archangel's Staff Amazing for trolling, or AP singed, as the mana will give you hp, since toggling Poison Trail does not stack it however, have fun getting mana through Fling and Mega Adhesive.
Rabadon's Deathcap: If you are getting fed or want Fling to nuke people, go for it.
Aegis of the Legion: Better for more of a support role, get it if you are struggling early on as it provides cheap overall tankiness as well as an aura, sell it lategame.
Randuin's Omen: Another supportish item. An amazing active that works well when you run into teams trying to get a fling, as well as decent tankiness in stats.
Warmog's Armor: Provides a **** ton of hp, pretty straightforward.
Shurelya's Reverie Great regen synergy with FoN, active is great, even if you have a support don't underestimate double Shurelya's, feel free to use it to pick up a quick fling if needed.
Summoner Spells
Singed doesn't utilize too many summoners but i'll run down the line real quick.
Ghost: Almost necessary for singed, use to catch up to fling and to run from people
Teleport: Used to go back for your catalyst which makes Singed a monster in lane. Gives you map control and a ***** to lane against.
Smite: Only when jungling, use to secure or steal buffs. If you build Will of the Ancients keep in mind smite procs the spellvamp.
Surge: Is ok when you want to splitpush or nuke with AP, not a strong choice overall.
Flash: Better against some champions than ghost, but worse against others. Up to you whether you want to take flash or ghost, I prefer ghost.
Revive: Good with teleport, but too long a cooldown most of the time to have much use.
Heal: Can be used on everyone really, but I don't like it on 
Singed as he is more of a passive farming laner, not an aggressive kill happy laner like Tryndamere Take it if you are really scared of a lane matchup.
Ignite: Good if you are not scared of needing an escape, is very deadly when used in conjunction with Poison Trail.
Clairvoyance: Save it for the support, if you are tank/support you could take it I guess.
Promote: You push the lane fast enough with Poison Trail no need for this.
Clarity: Singed isn't all that mana starved to begin with, especially if you start with a 
Sapphire Crystal a poor choice overall.
Cleanse: You get plenty of tenacity and CC reduction from 
Mercury's Treadsm
Juggernaut
mastery, and Insanity Potion. Not completely useless but a bad pick.
Boot Selection
Much like Summoner Spells, only a select few boots are good on Singed.
Mercury's Treads
My favorite choice, you have lots of movement speed from other sources, and the MR as well as tenacity is great.
Boots of Swiftness
I see many players grab this on Singed but the extra tenacity and magic resist of Mercury's Treads are just not worth the extra movement speed in my opinion.
Boots of Mobility
A possible choice if you are pushing then ganking side lanes ala 
Kassadin or 
Sion but it is just unreliable in my opinion, especially if you opt not to take Teleport. It helps when ganking from the jungle a bit, but makes you less tanky, and gives you hell early on in the jungle unless you start 
Cloth Armor anyway, but if you do not upgrade it into 
Ninja Tabi it means it is sitting wasted until you get a Randuin's Omen, Frozen Heart, or Aegis of the Legion
Ninja Tabi
The optimal choice for jungling, usually the best choice to upgrade from cloth armor which is the best start for jungling Singed in my opinion. Can be used in lane vs AD heavy champs like Garen, Tryndamere, or 
Renekton, but the usefulness of it drops off lategame.
Sorcerer's Shoes
Can be used for AP Singed or trying to push a lane advantage with kills, but Singed doesn't kill well in a straight up 1v1 lane fight anyway, and even when I play AP singed this is only situational.
Berserker's Greaves
AD Singed actually can work but no... just no.
Ionian Boots of Lucidity
I can see it on a tanky/support Singed ala 
Shen, but Frozen Heart provides a support aura and should be all the CDR you need anyways.
Lane Matchups
While Singed can really destroy some champions top lane, some can really shut him down as well. Here are some common lane matchups top and mid.
Top Lane Matchups:
Garen
Garen is a pain to deal with, especially if the Garen your laning against has specced 25 armor pen in runes as well as magic resist glyphs. Your only hope is to try to Fling him into tower range and go for a kill with Mega Adhesive and Poison Trail, but any smart Garen will know not to do this, and eventually he will outsustain you and win the lane. Try to bait him into tower diving you, then Fling him away and slow him, and hope the tower finishes the job. Tough lane.
Renekton
Another pain to deal with, as he has no mana to worry about, only fury that makes him do even MORE damage. My god. If he tries to get aggressive and dash to you, Fling him away and slow him, and get into cover of the brush then juke away. Trading with him unless you are under the tower is a bad idea. Take into account his 
Dominus as if you are not careful he will pop it when diving and just kill you. Another tough lane.
Olaf
You have to bully him early, but once he gets points into 
Reckless Swing and his 
Wriggle's Lantern the lane becomes awful. Beware if he has Ghost and is level 6, it basically means if you are low and cant outrun him you are dead. Zone him early and try to get an early Catalyst the Protector to press your advantage, but if the lane goes on too long you are going to lose.
Rumble
If you don't have much MR this lane is going to be a nightmare. Everytime you try to farm you are going to get a 
Flamespitter in the face. If you face a flamespitter happy Rumble, try to bait it and get him to overheat, but beware the extra damage he gets when his heat bar is yellow. He cant really kill you unless you play stupid, but watch out for 
The Equalizer when he hits level 6. The ult provides a humongous slow, and when done right, his full combo will end with a bonus damage from heat Flamespitter which can kill you really quickly.
Yorick
Not that bad a lane, his ghouls are annoying, but once you have Catalyst you can walk through them. You will have Catalyst before he gets 
Manamune so press your advantage while you can. IF you are having serious problems you can consider grabbing Ninja Tabi as well. He shouldn't kill you and you shouldn't really kill him either.
Tryndamere
It really depends on the way the Tryndamere you are against plays. If he is aggressive, let him push the lane to your tower then drop him if he tries to dive you. Bully him level 1 if you can before he has fury bar stocked up to crit you. Make sure you bring plenty of armor runes and grab a Ninja Tabi, but once he is level 6 and has 
Undying Rage be super careful and play smart, or you are going to end up dead, and a fed Tryndamere is a nightmare for you and your team.
Nasus
Easy lane you should deny him as much as possible, go for flings with your Poison Trail trailing behind you for strong harass, deny him cs at tower with a sight ward near tri bush/golem bush or entrance/exit to blue buff for jungle ganks depending on what side you are on.
More to come soon and on request.
Jungle Specifics
Start with Poison Trail unless you are nearly CERTAIN you will kill off a gank at level 2. In that case you may start Fling and grab Mega Adhesive at level 2. If you gank at level 2 and do not get the gank kill, you are pretty much ****ed, GL clearing jungle without your Q.
Start wolves at 1:40 with some help from mid/bot lane.
Head to blue buff with a leash from mid/bot lane.
Level Fling and go to gank or continue jungling.
Clear wraiths, then go back to wolves.
Gank here or continue jungling.
Clear red or golems, then clear the one you didn't clear right after.
You may not be high enough to gank, but if food presents itself, clean your plate, if you catch my jist =)
Clear wraiths, and if you are high enough, clear wolves and back.
You should always have Ninja Tabi on your first back, start your 
Hextech Revolver after finishing it.
Summary/Closing
Singed is a strong but situational pick. He beats some heroes top lane, and loses to his fair share as well. He is a strong jungler as well, but champions in lane with strong escapes really hamper him as he is not the fastest jungler, and taking his first blue buff really hampers him a bit. Remember that he can cleanup some heroes mid lane as well, and is an alright pick if you really want a tanky support. He is cheap, costing only 1350 IP and fun to play, especially when running from ganks then getting kills as you recall. Remember to use your Fling and Mega Adhesive correctly, and you will become a strong force in teamfights, even if you are feeding.
Happy Singing!
