Heartsteel Trundle Build

General

1. You play Heartsteel Trundle.
2. You rush Heartsteel #1.
3. You are gonna have tons of HP.
4. You build items that scale and/or benefit from HP stacking.
• And you build Armor and MR tanky items, depending on the situation and adapting to the enemy team.

General

1. You rush Heartsteel #1 unless it is going to be hard to proc it - they are all ranged and just poke you. Then you start slow with Guardian's Horn instead.

Item Order

1. Item Order after Heartsteel is flexible. You need to see what you need in particular game:
• Get Overlord's Bloodmail for more damage and AD.
• Get Warmog's Armor as anti-poke item (helps you stay in lane) and for some sweet HP.
• Get Unending Despair, if there are prolonged fights in which you can stay near enemies (or enemies near you). The items gets better, the more HP you get.
• Get various Armor and/or MR items to counter enemy team.
• Get Titanic Hydra for more fun , more damage and some survivability.

Items

1. Sundered Sky is very good damage item for this build (as #2-#4 depending on the game). It scales off your HP (so Grasp, Heartsteel, Overgrowth). It gives damage and pretty good sustain in fights. Remember to switch targets to maximize the effect!
2. Guardian's Horn is a surprisingly good item for its price. You can keep it for a very long time (or even have it as 6th item).

Runes

1. Second Wind scales off with your HP, so it is going to be powerful sustain rune. You can use it by purposefully triggering it by letting enemies poke you a little or walking over some harmful spells.
2. Triumph is better (heal + gold), but if you want to have easier time with your mana, go Presence of the Mind.

During game

1. Your main damage and power comes from auto attacks - Grasp of the Undying, Heartsteel
2. This is auto attack oriented Trundle build, so do it! Especially if running with Titanic Hydra and Sundered Sky as well.
3. You can prioritize switching between champions in the fight, just to farm more Heartsteel procs.
4. You need to adapt your items to the game. Enemy team heavy on AP? Buy MR. They heavy on AD? Buy Armor. You need some damage? Well buy that.
5. Remember to consume your Heartsteel procs!
6. Remember to consume your Grasp of the Undying 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.
