General Information

Welcome to our guide for Ragnaros, a Bruiser in Heroes of the Storm. Within these pages, you will find everything required to understand how best to play this hero, in both different map styles and team compositions.


Ragnaros's Overview

Ragnaros is a unique battle-mage-like Bruiser. His high proficiency at dealing large amounts of area of effect damage is offset by the avoidable nature of his Abilities. Opposing insects stand no chance against Ragnaros when he overtakes Structures (or their smoldering ruins), for his true power can then be unleashed... until a group of appropriately-geared adventurers go and claim their weekly treasures, that is.


Ragnaros's Strengths and Weaknesses

X Weaknesses
  • -Most Abilities are telegraphed and thus avoidable

Ragnaros's Empower Sulfuras Build has strong single-target damage and provides a high amount of survivability, especially while laning.

The damage comes from Blistering Attacks Icon Blistering Attacks at Level 7, Giant Scorcher Icon Giant Scorcher at Level 16, and Sulfuras Smash Icon Sulfuras Smash at Level 10.

After hitting enemy Heroes hit with Blast Wave Icon Blast Wave, Slow Burn Icon Slow Burn at Level 4 helps you land more Basic Attacks on fleeing enemy Heroes and helps you to connect Sulfuras Smash Icon Sulfuras Smash.

The survivability while laning comes from Sulfuras Hungers Icon Sulfuras Hungers at Level 1 that, after completing the Quest, will allow you to get more healing while hitting a full Minion wave using Molten Power Icon Molten Power.


Ragnaros's Synergies and Counters

V Ragnaros synergizes with

Ragnaros is at his best when coupled with Heroes that feature some form of reliable ranged crowd control so as to help him setup his own Abilities. He is particularly effective with Bruisers due to the Movement Speed increase provided by Blast Wave Icon Blast Wave.

X Ragnaros is countered by

As a generalist, Ragnaros is not particularly vulnerable or effective against anyone; still, his lack of crowd control makes him inadequate against some specific Heroes, notably Chen. He is also prone to be kited due to his lack of an effective gap closer.

Ragnaros's weaker maps

Since Ragnaros offers both excellent waveclear and sustained damage, and a reasonable amount of self-sustain, he is not particularly weak on any Map. Molten Core Icon Molten Core and Lava Wave Icon Lava Wave, however, make him exceptional at dealing with particular Map mechanics. Molten Core can specifically be used to absorb a number of Blackheart's Bay's or Sky Temple's Map mechanic attacks that would otherwise be aimed at Structures. Lava Wave heavily damages the Zerg wave on Braxis Holdout, and one Lane worth of Webweavers on Tomb of the Spider Queen. Molten Code does a good job of handling these mechanics as well, making Ragnaros particularly effective on these Maps.


Ragnaros's Tips and Tricks

  • Empower Sulfuras Icon Empower Sulfuras resets your Basic Attack; hit once, and then activate the Ability for a quick burst of damage.
  • Living Meteor Icon Living Meteor works best against Heroes that are running in a specific direction, such as during chases or escapes.
  • Blast Wave Icon Blast Wave can be quickly self-cast by holding ALT, and then pressing the Ability's hotkey (by default E).
  • Sulfuras Smash Icon Sulfuras Smash's Stunning effect can be used to setup for your own E-W-Q chain.
  • Lava Wave Icon Lava Wave moves very slowly, but might just catch opponents that are not paying attention by surprise.
  • Molten Core Icon Molten Core's effect can be used to mitigate the damage of certain Map Objectives, such as on Blackheart's Bay or Sky Temple.

Role in the Current Meta

Although labeled a Bruiser, Ragnaros works best when positioned at a midpoint within any given team's formation, somewhere between the frontline and the backline, so as to be able to make the most out of his positional Abilities. Without any non-Heroic crowd control and a very weak gap closer, Ragnaros is ill-equipped to be played like a typical melee Hero that would seek to single-out vulnerable targets. He is, however, incredible at following up on any crowd control or opportunity provided by allied Heroes. This makes Ragnaros a natural fit to any team composition that may be able to lock down their foes but lack that "finishing touch".

The features that makes Ragnaros stand apart from Heroes that fulfil a similar role, however, lie in two of his Abilities: Molten Core Icon Molten Core and Lava Wave Icon Lava Wave. These two Abilities have the capacity to outright counter or heavily impact certain Map mechanics. Molten Core is also particularly potent against teams that rely heavily on pushing to generate an Experience or Structural advantage. These Abilities will be discussed further, in the Abilities and Strategy section of this guide.
