Hello everyone, this is the way I build Trundle and how I play him. I've been playing Trundle as on off-main champion for quite some time now and I thought it was appropriate to try my hand on helping those in need of pointers or the newer Trundle players who want to know what the troll is all about. He takes some time to get the hang of, but after you got it all down he's an unstoppable force of destruction.

Greater mark of Desolation - In addition to his amazing tank murdering ability through his ultimate, these marks and quints will leave your target at little to no armor remaining, and being entirely physical damage he needs that boost.

- As a jungler, you can choose between armor and dodge, I prefer dodge for avoiding large attacks altogether in the later game against physical carries.

- CDR is a general glyph for me, it's probably the best choice as far as sustained dps goes because your contaminate cools down fast enough to leave your enemies in tears.

I use a 21/0/9 build as Trundle, I find that maximizing his damage output through masteries is better than for survivability, as Trundle has alot of that through his abilities already.

Start with Cloth Armor and 5 Health Potion, this should be self explanatory, then get Madred's Razors to further increase your jungle speed, get Mercury's Treads following that to make ganks extremely easy and make any cc attempt on you virtually useless, complete your Madred's Bloodrazor, by now the laning phase should be over and you'll need some survival for team fights, pick up Frozen Mallet for the health and slow, a guardian's angel for obvious reasons, grab a Black Cleaver and top it off with a Phantom Dancer and you're set.

Pros:
Amazing ganker
Unrivaled chase capability
Tank buster
Very tough
Moderate cc
Almost unaffected by cc

Cons:
Pillar of filth takes some practice
...I got nothing

Trundle is a jungler. Plain and simple. You can use what you have seen good results with as far as pathing goes, I personally find that starting at blue first and recalling after lizard to be the most successful. Theres not much to discuss here so I'll throw wards into play, get wards for your buffs as soon as possible, the enemy jungler or AP carry tends to attempt to take them from you mid-late game, secure your buffs and invest in wards, the kills from ambushing your foes will easily cover the ward prices needed.

As a jungler, your goal is to hurt your enemies and help your allies through ganks. Always remember that you'll need to gank the solo lane as much as you possibly can to let your teammate get some much needed farm, only gank if you know you can do one of three things:

1.Kill the enemy
2.Get the enemy to blow a summoner spell
3.Save a teammate

Any of these three goals are worth your time out of the jungle and will overall increase your chances of winning. Also on the ganking checklist is surprise, the single most important thing about ganking, NEVER let the opponent know you're there until you can ambush them without needing to chase too far, always try to run in from behind your target instead of running at them where they can see you ahead of time.

Trundle is a very position reliant ganker, make sure your allies know when you're going in so your enemies will be out of place and easy to pick off. Use Contaminate from the brush and a Pillar of Filth when they realise whats going on, ensuring their demise, as it's almost impossible to escape. When it comes to team fights, focus the carry and ult the meat shield, you can charge into a fight and come out almost unscathed with the enemy tanks defenses working in your favor.

All of Trundle's skills need to be explained to an extent to get the most out of them, Pillar of Filth can be used in 1 of 2 ways, either block an enemies escape route, or deny your own naive teammate from running into a 1v5 gank scenario. Rabid Bite usually has it's passive bonuses ignored, please don't ignore it, the AD bonus you receive and the AD leeching that happens to the enemy AD carry. Contaminate is useful in it's unique ability to cripple cc against you, always keep it up in any fight you enter. Agony is a DoT, a steroid, and an anti-tank ability, keep all 3 of these aspects in mind when using the ability, as it is very powerful when used correctly. The most unique thing about Trundle in my opinion is that he's balanced around steroid abilities, meaning he's not very item Dependant no matter how the game is going.

When you need to cover lanes, farming is generally poor, last hit what you can and let your passive bring you back up from the enemy harassment, remember as a jungler the majority of your gold will be from kills and assists so don't try too hard.

I know alot of people who come here looking for item builds for a champion expect the exact same item build to work for every game, but the truth is it won't. If you're fighting a team of all AP champions than pick up a Banshee's Veil or Force of Nature in place of another item, or a Thornmail for AD, the point is to adapt to your game and build what counters your opponents best while still building up your personal damage. Take everything in this build with a grain of salt, there are a few items we couldn't live without, there are others that are situational, and then just plain useless ones for the champion you're playing, please just use your best judgement to fit your team the best.

Well that's all I got for you all, hope you enjoyed the guide and it helped you in some way, best of luck to you all and as always, have fun.
