Greetings,Trundle main here this is my first guide ever!
I love Trundle that's why I'm making this guide and hopefully someone will find it useful.
Here I will show you how you'll become unstoppable fast hitting,healing tanky monster!Our home is beautiful isn't it? let's show those bastards what winter can do to them!

Ahh my favorite,attack speed on Trundle.
Take 9x AS on Trundle when in jungle you'll clear camps faster and you'll heal more.
Take AD runes if you're playing on Top.Armor protects you against those creatures in jungle,it's also good against auto attack champs and poke champs!1 is enough we still need to do some damage from our Q.Even faster smashing! 1 is enough though.Take 1 life steal it's good with your w + our AS will heal us even more!These are good against AP champs,poke and low cd champs also goes well with our tankiness!Scaling armor,these are good after lvl 9 you'll mostly be in the jungle so when you come out...Seal of scaling health is good for sustain even better with Spirit Visage.And...Same as the seals

Pros

Chomp This gives a short slow it has a very good chasing ability, it also gives Trundle some AD, of this amount the enemy loses half. This has a low cooldown and low mana cost,no longer works on towers.

Frozen Domain Gives you increased move speed and attack speed, this is the best ability you have for trades, it can be used as an escape,can only last 8 seconds so use this wisely, Frozen Domain should be used before Subjugate and the active from Blade of the Ruined King this will make the heals stronger and make you so too, this is the best combo for Trundle Also you destroy towers quickly with w+q.

Pillar of Ice This has a very big range so can be used to save allies or troll them, it is also good for escaping or blocking enemies from escaping.

Subjugate Perfect against tanks,in fights you should ult the enemy tank always.

More will be added soon!
Bilgewater Cutlass Is the core item for the troll,the active on it will help you win most fights the extra attack damage is perfect as is the lifesteal for sustain.

Blade of the Ruined King Oh yeah all you need right here. buy this then go full tank! Attack speed awesome,that life steal and active perfect,all we need in one item,you will survive longer in fights.

Boots Are really good on Trundle early, hard to evade especially with his Pillar of Ice + Frozen Domain

Spirit Visage Everything on this item is perfect,CD,healing increase,health,magic resist,health regen.

Randuin's Omen This is the best item it gives a lot of armor & health has an active, the best choice against auto attack based champions..

Dead Man's Plate Awesome item for chasing down your victims,enough armor,health,the passive is great.

Sterak's Gage My favorite item,awesome for surviving longer in team fights and if you're being focused.

Banshee's Veil Buy when you are being focused by crowd control effects,counter poke damage.

Thornmail Buy this if enemy team is pure attack damage.

Frozen Mallet It's good on Trundle but there are better items,this one is situational if you are having a hard time catching up someone.

Guinsoo's Rageblade It's good on the troll,some AD,AP for our ultimate and attack speed the passive is good,I would buy this only with Botrk.

Mercurial Scimitar Good item,never buy it over Botrk though.

Trinity Force Pretty good you may take it with Blade+Rageblade then 2 tanky last items if you're doing well, be careful though you'll be squishy. Good item for Trundle too.

Rapid Firecannon If you need a quick good item buy this. I like it on Trundle. if you know what I mean.

Phantom Dancer Like I said about Rapid but it's even better.

Hextech Gunblade If you want even more healing with botrk,Gunblade isn't that bad take it if the game is going well enough.

Statikk Shiv It goes well into my build also nice for split pushing. Take it if you're winning and being tank isn't an option.

Ravenous Hydra You may have seen every Trundle building this. not me. It's nice it has split pushing potential,damage and life steal. But there is something special about Blade of the Ruined King I can't resist.

Oh yeah. Just have something to say,if going on a lane 1 v 1 against a melee champ feel free to farm with your q,use your q on a minion then attack the enemy champ with AA be aware that you waste a lot of mana early game,don't spam it too much.
Against range champions when you're comfortable enough place your Pillar of Ice behind the enemy champion quickly Frozen Domain and bite his meat Chomp

While in the deep deep jungle.

I will be updating this guide frequently I know it sucks now but it's a start and I need your opinions.
If you win a game with this build you can take a screenshot and send it to me and I shall put it here for other viewers to see.
Here are some of my games:

Precision "Improved attacks and sustained damage." Let's start with these as I feel this set is the best for Trundle right now.
Press the Attack PASSIVE: Basic attacks versus champions apply stacks. Attacking a new target removes all stacks from the previous target. At 3 stacks, the target takes 30 - 120 (based on level) bonus Ability powerAttack damage Adaptive damage and is made Vulnerable, taking 12% increased damage from all sources for the next 6 seconds.
With Trundle you activate it with just q + basic + basic in less than 2 seconds.
Triumph PASSIVE: Champion takedowns restore 15% of your missing health and grant an additional Gold 25. This one is useful and can save your life most of the time. Imagine dueling someone both of you are low on health he ignites a ignite! on you you just get that last Q and kill him your health goes to 10 bom! you get 15% more from this rune.
Legend: Alacrity PASSIVE: Gain 3% (+1.5% per Legend stack) bonus Attack speed icon attack speed, up to 18% with 10 stacks.
LEGEND: Gain Legend stacks for every 20 points earned, up to 10:
20 points for champion takedowns
20 points for epic monster takedowns
5 points for large monster kills
1 points for minion kills
Do I have to even explain? Attack speed is everything for our troll.
Coup de Grace PASSIVE: Deal 10% increased damage to champions below 40% health.
Additionally, you gain 9 bonus Attack Damage or 15 Ability Power (Adaptive) for 10 seconds whenever you score a champion takedown. This bonus does not stack.
ADAPTIVE: Grants bonuses based on which stat you already have the most bonuses for. Defaults to the first listed. When you get those bastards to low health EASILY with your beast mode and my guide when they reach low health finishing them will be easy thanks to this bad boy,de Grace! oh and 9 bonus AD when you kill someone and bonus AD from our Q?! double kill!
Inspiration I love this look below!
Future's Market PASSIVE: You can enter debt to buy items, up to Gold 150 (+ Gold 5 per Minute), which is displayed as negative gold in your treasury.
Your first loan is Gold free, after which you will be charged a Gold 50 lending fee. The fee is added on to the amount you owe after leaving the shop.
You cannot borrow money before 2:00. I'm loving this a lot and can be useful in lane or jungle since we benefit with more items! more items early game more power and benefit! World domination.
Cosmic Insight PASSIVE: Gain 5% Cooldown reduction icon cooldown reduction and increases the Cooldown reduction icon cooldown reduction cap to 45%. Additionally, reduces the cooldown of summoner spells and item actives by 5%. CDR is nice to our abilities less cooldowns and we can spam our q more.
