In the fiery world of Monster Hunter Wilds, securing the elusive Flame Sac and Inferno Sac is key to forging powerful fire-based weapons and armor. But these rare materials don’t come easy-they require hunting down some of the fiercest fire-breathing monsters like the Guardian Rathalos and Yian Kut-Ku. Ready your weapons and prepare for a blazing challenge as we guide you through where to find these coveted sacs and how to use them to ignite your arsenal.
How to get Flame Sac and Inferno Sac in Monster Hunter Wilds
In Monster Hunter Wilds, the Flame Sac is a Low Rank material obtained exclusively from the Guardian Rathalos, which can be found in the Ruins of Wyveria. This sac has about a 20% chance of dropping after defeating and carving the Guardian Rathalos, and it is essential for crafting fire-element weapons in Low Rank. To farm it efficiently, players should focus on Low Rank quests targeting this monster and use the Wishlist feature at the Smithy to track needed materials. On the other hand, the Inferno Sac is a High Rank material dropped by several fire-element monsters, including Yian Kut-Ku, Rathian, Rathalos, Guardian Rathalos, and Gravios. These monsters can be found in various regions such as Scarlet Forest, Oilwell Basin, and Ruins of Wyveria. The Inferno Sac is used for crafting and upgrading High Rank fire-based weapons and armor. Hunting these monsters repeatedly increases the chance of obtaining Inferno Sacs, which are crucial for progressing in High Rank fire equipment crafting.
The Flame Sac is a Low Rank material that exclusively comes from the Guardian Rathalos, which you’ll encounter toward the end of the main campaign, once you reach the Ruins of Wyveria. It’s an infrequent carve from the monster, and will only drop about 20% of the time. Notably, the other Low Rank fire monster, Quematrice, cannot drop a Flame Sac and uses a different mechanism to create its flame attacks.
The Inferno Sac is the High Rank version of the Flame Sac, and comes from far more monsters than its predecessor. Here are all the High Rank monsters that can drop an Inferno Sac in Monster Hunter Wilds:
- Yian Kut-Ku
- Rathian
- Rathalos
- Guardian Rathalos
- Gravios
Each time you kill these monsters you’ll have a small chance to get their Flame Sac or Inferno Sac, depending on which they drop.
What to use Flame Sac and Inferno Sac for in Monster Hunter Wilds
The Flame Sac and Inferno Sac in Monster Hunter Wilds are crucial materials used primarily for crafting fire-based weapons and armor. The Flame Sac, a Low Rank item, is obtained exclusively from the Guardian Rathalos and is necessary for forging weapons in the Guardian Rathalos fire weapon tree. In contrast, the Inferno Sac is a High Rank material dropped by several fire-elemental monsters including Yian Kut-Ku, Rathian, Rathalos, Guardian Rathalos, and Gravios. It is used to craft and upgrade a wider range of fire-themed weapons, armor, and charms, including equipment related to Kut-Ku and Quematrice. Both items are essential for players aiming to build powerful fire-element gear as they progress through the game’s ranks.
The Flame Sac and Inferno Sac are primarily used for crafting fire weapons and armor based on fire monsters – go figure.
In Low Rank, you’ll need a Flame Sac from the Guardian Rathalos to build any weapons in the Guardian Rathalos tree that deal fire damage. Hammer enjoyers, for example, will need three Guardian Rathalos Scales, two Guardian Rathalos Webbing, and one Flame Sac in order to craft the Albirath Bludgeon. You won’t need any Flame Sacs to build the Guardian Rathalos armor set.
In High Rank, you’ll need an Inferno Sac for multiple different projects, including some pieces of the Kut-Ku armor set, Kut-Ku weapons, Quematrice weapons (funnily enough, considering it doesn’t drop any), High Rank upgrades to your Low Rank fire weapons, and more.
What’s the easiest way to hunt fire monsters for Flame and Inferno Sacs
The easiest way to hunt fire monsters for Flame and Inferno Sacs in Monster Hunter Wilds is to target the Guardian Rathalos in Low Rank for Flame Sacs, and for Inferno Sacs, hunt High Rank fire-element monsters such as Yian Kut-Ku, Rathian, Rathalos, Guardian Rathalos, or Gravios.
To efficiently farm Flame Sacs, join Low Rank quests that feature Guardian Rathalos, especially the optional quest “His Eternal Reign” in the Ruins of Wyveria biome, where the monster roams. Using traps like Shock Traps and Pitfall Traps, as well as exploiting its weaknesses to Dragon and Thunder elements, Sleep, Paralysis, Blastblight, and Stun, can make the fight easier. Capturing the monster instead of killing it can also reduce the time needed for repeated hunts.
For Inferno Sacs, focus on High Rank hunts against the listed fire monsters, as they have a chance to drop this rarer material. Joining multiplayer hunts or SOS flare quests can speed up locating and defeating these monsters. Keep in mind that both Flame and Inferno Sacs have relatively low drop rates (around 20%), so persistence is key.
What traps or tactics make Guardian Rathalos easier to hunt for Flame Sacs
To make hunting Guardian Rathalos easier for Flame Sacs in Monster Hunter Wilds, use a combination of traps and tactical tools:
-
Shock Traps and Pitfall Traps are highly effective to immobilize Guardian Rathalos, giving you crucial windows to land heavy attacks.
-
Flash Pods are essential to bring the Rathalos down from the air, as it spends most of the fight flying and is difficult to target otherwise.
-
Exploit its elemental weaknesses by using Dragon and Thunder-based weapons to deal increased damage.
-
Utilize status effects like Sleep, Paralysis, Blastblight, and Stun to further incapacitate the monster, making it easier to control the battle.
-
When the Rathalos is grounded, focus on breaking its wings to reduce its aerial mobility, and target its head to reduce the frequency of its fireball attacks.
-
Capturing the Guardian Rathalos instead of killing it can save time for repeated hunts, as capturing often yields better rewards and shortens the fight duration.
These tactics combined will help you efficiently hunt Guardian Rathalos and increase your chances of obtaining Flame Sacs.
