Singed.

Generally we always want to take Ghost as movement speed is king on Singed .

Secondary summoner spell should ideally be combat orientated so Ignite / Exhaust (if against heavy AA) is ideal and helps provide grievous wounds as we lack it from Insanity Potion (R) and Morellonomicon is not great for us.

We also take Summoner's Wrath in our masteries so these are all upgraded for us.

You can run Teleport instead but I find the movement speed we stack throughout the game provides us enough mobility to clear side waves and rotate for team fights and the combat summoner spell provides a 1v1 threat that we might otherwise lack.

Always max Poison Trail (Q) , you can afford to leave of a point in Mega Adhesive (W) until at least level 4 as it doesn't ground or root when we flip champions into it and the extra point in Poison Trail (Q) early helps clear waves.

Singed has the best wave clear level 1 and can shove to get to level 2 and Fling (E) your lane opponent into your wave; combined with Ignite or Exhaust can sometimes cheese a first blood.

Quintessence of Movement Speed are your go to Quints every single game as Singed.

The above rune page is a general / safe top lane rune set-up; however seals/glyphs can be swapped for scaling runes depending of match-ups - Seal of Scaling Health / Glyph of Scaling Magic Resist / Seal of Scaling Armor runes generally break even and start to surpass Seal of Health / Glyph of Magic Resist / Seal of Armor runes around level 6.

They can be used instead if the stats they provide as flat runes aren't needed for the laning phase itself or if you are feeling confident and looking to scale harder into the mid/late game for team fights.

Going 21 points into the utility tree provides Singed with very useful stats and/or utility that we either can't buy or get as easily through other methods, and we make use of every point invested very well.

Expanded Mind and 2 points Durability have good synergy together alongside our passive Empowered Bulwark (P) .

Perseverance / Strength of Spirit provides more sustain for lane / into mid game. Meditation alongside Catalyst the Protector allows us to skip picking up a Doran's Ring for mana sustain and helps accelerate us towards Rod of Ages .

Biscuiteer gives us a Total Biscuit of Rejuvenation for even more lane sustain.

Crystalline Flask breaks even when compared to potions and Doran's Ring when we sell it after consuming about 4 charges (so just after 1 refill) and will restore 360 HP / 180 mana per base and can be refilled easily at least 6 times a game quite easily. Doran's Ring costs 55g more and only sells for 22g more (160g vs 138g) than Crystalline Flask and provides 1/6th of its effective HP not accounting for refills.

Try to keep Crystalline Flask in your inventory until your looking to complete 4th / 5th item as its more effective than single components like Ruby Crystal / Sapphire Crystal .

Improved Recall allows us to more quickly reset after a proxy off shoving wave and will be used plenty to help get back to lane and refill our Crystalline Flask.

We could invest 21 points into the offence or defence trees (which is still viable) but we really need mobility due to lacking our modern Noxious Slipstream passive. With this mastery setup we have about 10% additional movement speed out of combat (Wanderer, Nimble,3x Quintessence of Movement Speed ) which stacks on our flat movement speed from Boots of Swiftness - alongside an additional 6% from Twin Shadows makes us very fast, allowing us to move around the map and help dodge skills-shots.

We will have around 445 movement speed without Ghost / Insanity Potion (R) and have around 510 / 650 under the influence of both. Whilst not as fast as modern Singed potentially can be; this requires less let up / drifting between champions. Due to to the lack of general mobility in classic, it will make you very difficult to catch and pin down, especially when spreading Rylai's Crystal Scepter slow via Poison Trail (Q) .

For reference, Master Yi with his Highlander (R) will struggle to catch you.

We also have passive gold income via Greed and Pickpocket to help accelerate our items and power-spikes and has some synergy with Lucky Pick. Pickpocket should be swapped with Explorer if you are 100% going to proxy and/or playing against ranged to help scout the enemy jungle alongside your trinket as you are never going to make use of Pickpocket

Swap Hardiness / Resistance in the Defence tree depending on lane opponents damage type although note that armour generally scales better due to minions/towers and AAs that cannot be dodged unlike some spells.

Summoner's Wrath in the Offense tree is a 1 point wonder as we take both the Ghost and either Ignite or Exhaust summoner spells.
