Heartsteel Rek'Sai Build

1. You play Heartsteel Rek'Sai.
2. You rush Heartsteel #1 and stack as much HP as possible.
3. You build items that scale and benefit from HP, then add Armor and MR depending on the enemy team.

1. You are an ultimate bush master (more in Tips and Tricks section). It is especially important when playing Heartsteel Rek'Sai.
2. You can be really good peeler. Enemy going after your carry? Stay close to your carry and knock them up with your Unborrow (W) to peel the enemy off. More enemies coming? Just burrow and knock them up, one by one, as well!

Getting started

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.
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).

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.

During fights

1. Your main damage and power comes from auto attacks - Grasp of the Undying and Heartsteel.
2. This is auto attack oriented Rek'Sai build, so do it! Especially if running with Titanic Hydra or Sundered Sky.
3. You can prioritize switching between champions in the fight, just to farm more Heartsteel procs.
4. Remember to consume your Heartsteel procs!

Adapting

1. 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.
2. Sundered Sky is very good damage item for this build (as #2-#4 depending on the game). It scales off your HP. It gives damage and pretty good sustain in fights. Remember to switch targets to maximize the effect!
3. You can use Bandlepipes to give your whole team an attack speed boost whenever you CC enemies. Great synergy with auto attackers.

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. Remember to consume your Grasp of the Undying procs!

1. You can use your Void Rush (R) for survivability and disengage. Getting focused really hard in the fight? Use it, so enemies will lose target, stop attacking you, so then you can run away.
2. You can use your Queen's Wrath / Prey Seeker (Q) (when burrowed) to scout bushes.
3. You will detect enemies moving in the bushes thanks to Burrow / Un-burrow (W) (passive part while burrowed).
4. Your ally got hit with a Snowball? Burrow and go close to them, to knock them up when they arrive. You can even time it to knock them in the air. Often it will be certain death for enemy player.

1. Keeping tunnels spread out across the map will ensure you have choices when you want to cast Void Rush.
2. Cast Burrow before travelling around the map to take advantage of the increased Move Speed and the safety provided by Tremor Sense.
3. Tremor Sense can warn you of enemies closing in, and is particularly useful when entering enemy territory.
