Heartsteel Amumu build with runes and items. Heartsteel Amumu guide offers in-depth how-to play, skill order and tips. Play Heartsteel Amumu build in League of Legends Patch 25.05!
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.
How to play
General
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
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
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!
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
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.
Triumph is better (heal + gold), but if you want to have easier time with your mana, go Presence of the Mind.
During game
Your main damage and power comes from auto attacks - Grasp of the Undying, Heartsteel
This is auto attack oriented Amumu build, so do it! Especially if running with Titanic Hydra and Sundered Sky as well.
You can prioritize switching between champions in the fight, just to farm more Heartsteel procs.
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.
Remember to consume your Heartsteel procs!
Remember to consume your Grasp of the Undying procs!
Tips and Tricks
Champion
You have great engaging tools - Bandage Toss (Q) and Curse of the Sad Mummy (R)! Always play with the team and do not be shy and do not wait for 'special moment'!
You can pretend to face another direction / go another direction to land easier Qs.
Simple and easy, but excellent combo that wins fights is: Bandage Toss (Q) or Mark (Snowball) to a minion + Flash into an enemy team + use Curse of the Sad Mummy (R).
Riot
Amumu is highly dependent on teammates, so try laning with your friends for maximum effectiveness.
Cooldown Reduction on Amumu is very strong, but it's often difficult to itemize for it. Grab the Golem buff whenever possible to gain Cooldown Reduction without sacrificing stats.
Despair is very effective against other tanks, so make sure you're in range of opponents with the highest Health.
