AP Trundle Build

General

1. You play as Mage building Burn items.
2. You rush Liandry's Torment.
3. You burn your enemies. With DOTs. And debuffs.

General

1. Playing AP Trundle build, your default rush is Liandry's Torment vs. HP, Blackfire Torch vs. squishes. Then get the other item
2. Adapt to an enemy team. Are they full of tanks, and they rush tons of Magic Resist? You rush Void Staff as #2 or #3 item to counter MR stacking. Their team has champs with lots of healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item).
3. Items like Morellonomicon or Oblivon Orb are extra effective with this build, thanks to damage over time effects from Liandry's Torment.
4. An enemy team has an extremely strong shielding? You can get Serpent's Fang to counter it. It works with your DoTs, meaning shield reduction lasts longer.
5. Somebody is going after you each fight? Always getting ulted by enemy assassins? Rush Zhonya's Hourglass.
6. If you are doing well, are ahead and want to have some fun, you can buy The Collector item. It works off your damage over time effects!

Champion

1. This AP Trundle build is fun build to play against tanks and bruisers. If an enemy team is full of squishes, you can try getting Luden's Companion or going another build.
2. You play around your Subjugate (R) - ult target with most HP to see him melt.
3. Trundle has AP scaling only on Subjugate (R), to offset that you can buy items like Lich Bane or Nashor's Tooth. But only when you really can use your auto attacks!
4. Serpent's Fang works with your Pillar of Ice (E)!

Champion

1. You can stop an enemy team from pushing your turrets with your Pillar of Ice (E). Everyone died, and the enemy tries to push? Just put E on minions' path.
2. Your Subjugate (R) shreds Armor and Magic Resist by 40%. It is often recommended to use that on enemy tank. This way, you are getting more tanky and can go into fights. Or R enemy tank to burst him down quickly when he comes at your team. Or even some bruiser tries to go all in? Well, Subjugate him.
3. Your Pillar of Ice (E) knocks enemies back from its center. This implies some cool interactions like with Samira's Passive or with Yasuo's Ultimate!
4. Your Pillar of Ice (E) knocks back, so you can use it to interrupt some cooldowns or CC, even in melee range.
5. Your Pillar of Ice (E) can interrupt casting if you cast it on top of enemy champion. If there's Fiddlesticks on an enemy team, you can try interrupting his ult.
6. Weave your auto attacks with Chomp (Q) to maximize damage! Auto - Q - Auto. This works also against turrets.
7. Your Frozen Domain (W) increases healing taken. Use it when taking Health Relic, when there are bigger minions that die (your Passive heals off minion maximum health!), when using R or when there are enemy champions about to drop!

Riot

1. Trundle excels at fighting within his Frozen Domain. Try to draw enemies onto it.
2. Use Subjugate to soften a powerful enemy tank or to create a target for your team to focus fire.
3. Chomp is good for lowering the physical damage of enemies; try to focus it on enemy physical damage dealers.
