My first guide- Bwhahaha. Mad chemist powers, an amazing passive, and great initiating abilities make Singed an extremely fun champion to play. There are a few things to know before hand though.

-You are NOT invisible, you are just as tanky as everyone else in the beginning.

-Your "Q" cost mana! You can't just spam your "Q" (Poison Trail) all the time.

Lets get started!

All right. I generally use flat magic penetration marks for your Poison trail and your Fling. I take flat Armour seals and magic resist glyphs. The Quints of Swiftness just make it a little easier to get around, which as the team fight initiator, it means a lot if you get taken on by all the champions and have to make the quick getaway.

I go 0/9/21 in my masteries just to get the health per level in defense. The twenty one down the utility tree mainly for the cooldown reduction. It helps a TON with your flip as it has a relatively high cooldown.

I start with the Sapphire Crystal just to help with your passive, and with the point in your Poison Trail you can use it for a little while longer. I also always start with the health potions because of the early game ignites, and for the fact that you're not tankier than anyone else at the beginning. You really want to rush Catylyst, so focus on last hitting minions for the first part of the game. Once you get Catylyst, you can use your Poison trail to kill minions and get almost EVERY last hit. Make sure to toggle your Poison Trail though, as it does cost a lot of mana. After Catylyst, I try to save up until I can go back and get both boots and the blasting wand for the Rod of Ages. I find rushing Rod of Ages is the best idea because it gives an additional 525 mana, which in turn helps your passive. After Rod of Ages, I get get Boots of Swiftness because the majority of champions get tier two boots and outrunning them while their chasing you is a HUGE advantage as long as you have your Poison Trail activated. After that, I work a Force of Nature purely for the health regeneration and how tanky you have become purely based on your mana. After working the force of nature, if you're well fed, go for the Deathcap, but if you are the initiator and are being really focused, I love the Warmogs. Especially because of its passive and the fact you can just run around minions with your Poison Trail. After that, I get the Deathcap. Make your poison annihilate anything, aside from really tanky champions. Rounding off the build with a Spirit Visage for, you guessed it! Even more tankiness! If you're doing good, you can easily switch out the Spirit Visage for a Rylia's Crystal Scepter, if you were to want to, It is a good alternative item as the slow from its passive helps you kite your opponents better.

I ALWAYS take Ghost on Singed, as it adds to his Ultimate. It also helps early game before you get his ultimate if you get caught in a tight situation and need to get out fast.

The next one I take is always a toss up. Sometimes, I take flash to help the close-quarters and sticky situations. Sometimes, I also take Exhaust so the carries around me can get the kill. However, I seem to have the most success with ignite. It seems whenever I get a champion low, they seem to flash or use an ability to get away and barely escape death by poison. Ignite solves this, and can secure kills early and late game.

Farming, as I have stated, gets insanely easy after you get your Catylyst. Your poison, along with selective hitting of the low-health minions, you are guaranteed so many last hits. Before your Catylyst, however, you need to be VERY selective about the minions you hit and just try to get as many last-hits as possible.

Pros
-One of the Best tanks
-Very good escapability
-Amazing late game farm

Cons
-Mana problems early if you use your "Q"
-Fairly slow without your boots (Slow early game)
-Bad early game farm

I always take the early point in Poison Trail and max it at level 9. I do this for those early lane fights. You get a BIG advantage in those. I take the point in fling at level 2 and max it at 13. I put a point in mega adhesive at level 4, as it mainly helps you kite and get away from opponents that you don't really need early game. I max mega adhesive last. I put a point in my Ultimate whenever I can.

Well, I hope you guys enjoyed and learned some things about Singed that you didn't know or didn't think to try. As I stated prior, this is the first guide I have made and there might be a few flaws, and a lack of visually appealing aspects (Too lazy to look up how to do it, I will figure it out, however). Once again, I hope you guys enjoyed, and thank you for reading!
