 How to get
|Golden Molten Giant||1600||400|
- The mana cost of a Molten Giant is in reduced by 1 for each point your hero is below their maximum Health. It is not affected by the total damage taken in the game, only the current level of the hero's Health compared to their maximum. For example, if a hero's Health is lowered from 30 to 15, Molten Giant's cost will be reduced by 15, for a cost of 5 mana; however, if a hero's Health is lowered from 30 to 15, then restored to 25 using healing abilities, Molten Giant's cost will only be reduced by 5, for a total cost of 15 mana.
- All regular heroes have a maximum Health of 30. However, the warlock legendary Lord Jaraxxus creates a 15 Health hero. Since 15 is the maximum Health of this hero, only damage taken beyond this level will reduce the cost of Molten Giant. Damage taken by the warlock before playing Lord Jaraxxus will not affect the cost of Molten Giant once Lord Jaraxxus has been played.
- Molten Giants have the best synergy in warlock decks or decks that revolve around Health manipulation.
- With their Life Tap hero power, warlocks are able draw cards at a quicker rate as well as self-inflict damage to lower the casting cost of the unit. Adding one or two Molten Giants coupled with cheap taunters such as Sen'jin Shieldmasta will guarantee you heavy hitters as early as mid-game while at the same time protect your lowered Health Points from further weapon or minion attacks. Add Drain Life and Siphon Soul, for Health regeneration after using this combo. Couple them with Lord Jaraxxus to make the best out of Health manipulation decks.
- Priest, druid, and paladin decks are all able to use Molten Giants with some success due to their healing cards and abilities. While lacking this synergy, the card can still be used effectively during the late game by any class.
Molten giants are a type of giant that live in warm mountains and underground. Most live in the Molten Core. Small glowing yellow eyes peer out of a massive red stone skull. In fact, this creature's entire body is formed from chunks of red stone, even what appears to be a beard or mane. Its arms and legs are thick pillars of rock, and every inch is covered with molten veins. Molten giants are the brutal and cunning front-line defenders of Ragnaros' army.
Ragnaros pulled some of those giants from the heart of the Firelands to the Blackrock Mountain and the Molten Core. The Earthen Ring has all shamans forbidden to summon, control and direct those unpredictable and violent fire elementals. The use of such coercion could trigger an event similar to the Cataclysm, if the elements grow sufficiently angry. Garrosh Hellscream recently ordered his dark shamans to force Molten giants into battle.
