Hextech Rocketbelt Trundle Build

General

1. You rush Hextech Rocketbelt #1, Liandry's Torment #2.
2. You get Cosmic Insight rune to use Hextech Rocketbelt more often.
3. You poke with Hextech Rocketbelt and First Strike to earn gold and burn enemies.
4. After core items, you adapt. You can play as a tank or as a damage dealer.

General

1. Use Hextech Rocketbelt active to poke your enemies all the time, earning gold with First Strike.
2. Adapt to the enemy team. Build tanky or more damage. You can play as a utility tank, poke, or even you can go some AD items to still have plenty of damage. Depends on the team and how you want to play.
3. For utility tank, remember that Liandry's Torment works good with Serpent's Fang (to counter shields) and Oblivion Orb (to counter healing).
4. Cosmic Insight reduces the cooldown of all active items, so Zhonya's Hourglass really works well with this build.
5. Wait for the First Strike and proc it with your combo, to deal damage and earn gold.
6. Be careful to not get poked, because you waste First Strike procs.

Items

1. Be careful when playing Fimbulwinter, as your Pillar of Ice (E) triggers this item and you waste shield proc!

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.
