Singed descended from a long line of Zaun's revered chemists. Even in his youth, his talent for concocting potions far outstripped that of his peers, and he quickly distinguished himself from his less extraordinary chemist compatriots. It came as no surprise to anyone when he was selected for apprenticeship by the infamous Warwick, master apothecary on a lucrative retainer with the Noxian military during their campaign against Ionia. Within Warwick's laboratories, Singed toiled without end, rapidly absorbing every detail of his predecessor's deadly craft. Singed had little concern for the death and destruction that was the fruit of his labors. By the time the curse of lycanthropy descended to claim his master, Singed was poised and eager to make the transition from workhorse to innovator; he was ready to share his genius by bringing a new brand of suffering to the Ionian front. His zeal for progress was unquenchable, and when suitable test subjects proved to be in short supply, the eager chemist was often thought to turn his volatile mixtures on his own flesh.
When the uneasy peace created by the League of Legends settled on the world, Singed journeyed to the one place where he was still able to showcase his beloved craft: the Institute of War. By this time he was barely even a man, his body both ruined and sustained by his ingenious craft. A thousand burns - accidents of shadow and flame - mar his ravaged form, and exposure to such harsh conditions has deadened his nerves, hardened his body, and strengthened his physique, transforming him into a veritable juggernaut. This, combined with a formidable arsenal of deadly concoctions, make Singed a force to be reckoned with on the Fields of Justice.

"My deadliest dose shall bear my patron's name!" –- Singed, having just christened the Insanity Potion

-VERY FAST

-Great damage
-Can easily carry the team and a must in team fight

CONS


-Not very effective against magic resist items (If you are new and don't know about counters)
-Doesn't Jungle well (kills Baron and Dragon pretty slow)
-Slow attack speed (unless you get an Elixir of Agility... ONLY DO THIS LATE GAME!) meaning buildings take longer to go down (Unless you pop ult)
-Mana runs out quick early game (levels 1-5) if played to aggressively (Take 1 Mana potion to help)

Passive: Empowered Bulwark - (Innate): Increases Singed's health by 2.5 for each 10 points of mana he has

A decent passive but your not going to build all mana so it has little use. But it is nice to have that extra mana.

Q: Poison Trail - (Toggle): Singed lays a poisonous trail which deals 22 / 34 / 46 / 58 / 70 (+30% of ability power) magic damage per second.
Cost: 13 mana per second
Cloud radius: 20

One of Singed's important spells. This spell is extremely mana hungry at the beginning and if over used u can run out of mana fast. With this build the poison trail is deadly at 300 some dmg per second. Some ppl like having a Rylia's Crystal Scepter to do slowing as well. But i dont like it because it wrecks the whole reason on having them follow you. Remember to turn this on when your farming, running away, and in teamfights, and always conserve your mana. If your bored u can always cover an ally champion with smoke :D especially if u have Riot Singed!

W: Mega Adhesive - (Active): Throws a vial of mega adhesive on the ground causing all enemies who touch it to be slowed as long as they are in the adhesive and for 1 second once they are out of it.
Cooldown: 14 seconds
Range: 1,000

This spell can save your allies' and your life (Its nice getting a Thank You from an ally). Or you can use it to slow an enemy down to fling. This is one of the games best slow.

E: Fling - (Active): Singed flings an enemy over his shoulder, dealing 100 / 150 / 200 / 250 / 300 (+100% of ability power) magic damage and slowing the enemy when they land.
Cooldown: 10 seconds
Range: 100
Flip distance: 550 (estimate)

This is one of Singed's most messed up spells (I Know thats just crazy). Plz dont fling champs away from teammates when they r trying to chase the enemy. Only do that to save someone. But other wise if your a mean person this is a great spell to ks when you have high ap. Great for interrupting ults such as ww's or nunu's. Remember use tactics when using this spell. Ex. Flinging the enemy into a turret.

Ultimate: Insanity Potion - Singed drinks a potent brew of chemicals, granting him 35 / 50 / 65 enhanced damage, attack speed %, ability power, armor, movement speed, and regeneration per 5 for 25 seconds.
Cost: 150 mana
Cooldown: 100 seconds

This is great if you r running away or chasing down someone. It is also a good tool too trick someone to continue chasing u because of your low health while u use your ult to heal.

For summoner spells I use Ghost and Exhaust.

Ghost is great to add that extra speed to catch someone or run away. It works well with your ult. This is the must have for Singed.

Exhaust is great to do more slow to someone your chasing or you can also use it too escape from someone. This spell is great especially when combined with a turret. If your low on health you can fling get them in turret range then use your ult and exhaust and then the enemy champ is screwed. Or u can fling someone in turret range and use it as a slow to keep them in turret range.

Another good spell for Singed is Cleanse

Cleanse is great for all tanks because they are the ones that go in and take the damage and you dont want some lousy crowd control to stop u from getting a kill.

The Doran's ring is a great item for singed at the beginning. It provides the much needed mana regen when you r using your poison trail and ap to boost the dmg. I recommend this item highly for solo laning. (I play a defensive game in the beginning making this useful because im not running in and getting my health drained away)
* Alternatively you can get the basic boots first so you can quickly run and fling.

The Boots of Swiftness is a must get for Singed. This is what makes him fast and this will lead to you catching more ppl with fling. I do not recommend any other boots.
*Some ppl like the Mercury Threads it is good tank boots but not really worth it unless they have alot of ap or cc.

The Rod of Ages is also a must get for Singed. This item works well with its passive because it gives mana and health. And the passive takes the mana and makes more health! YAY! It also give a decent amount of ap making you more deadly and tanky. Cheap and Effective HP item giving 812 extra HP when maxed.

The FoN is my favourite even when the other team has no magic caster. First of all it increases your movement speed and it increases health regen. This is the item that helps you run away AANNDD if the person is STUPID enough too follow u he well slowly loos health while you run in circles getting healed and then you go and attack
*This item can be postponed for ad resist items if needed.

By this stage you my want a good synergy with your Poison Trail. This is why u get a Sunfire Cape. Not only does it give you health it does dmg per second wich is pretty useful.
*Remember dont stack sunfires they r unique. Man i miss the days when you could do that.

Now if you got all your tank items u u should get something that gives you big ap like a Rabadon's Deathcap. This item makes your fling do 600 some dmg and your Poison Trail 300 some. Now YOU ARE INVINCIBLE and scary. BUHAHAHAHA!

Other items you can get includes the Zohanya Hourglass after you get Rabadon's, Rylia's Crystal Scepter, Thornmail if your against ad champs r they ad champ scares you, and Randuims Omen if they r ad. Magic resist items to get include Quicksilver Sash and BANSHEE VEIL (this item is pretty good for Singed).

An item i havent tried yet for singed is an Archangels Staff. I think it might be good with singed ill report back with my findings

I dont think i need to discuss into this topic but if you need help farming u use q and click in circles around minions and toggle off the q when the last one is almost died. Stay behind and just get experience if you are getting over harassed and your team mate aint that good.

Another Strategy if over harrased is waiting for minions to die against the tower, then h***ing the opposing minions as they advance is a simple, yet effective strategy for farming lanes, and keeping enemies far away.

You can get a gold giving item if you fell that you r not getting enough money. For this I only recommend one.

Thank You For Reading this Guide! Hope u have fun playing Singed!

THANKS TO Ezreal and Guinsoo for developing SINGED!

Any comments I will take into serious considerations and add it on

Singed's line, "To shake, or not to shake," is a play on "To be, or not to be," a famous quote from William Shakespeare's play Hamlet.
His /joke "Shaken, not stirred." is a reference to the famous quote of James Bond.
His /dance is the "Jump on It" dance from The Fresh Prince of Bel-Air.
