The Tempered State (Japanese 歴戦の個体 Rekisen no kotai, roughly "battle veteran specimen") is a phenomenon in monsters that heightens their aggression. Tempered Monsters are old, experienced monsters that have been living in the New World for a long time. From them living in the New World for so long, these monsters have gained the bioenergy of Elder Dragons. Every large monster in Monster Hunter: World and Iceborne can be affected by the Tempered State (including Elder Dragons, Subspecies, and Variants) except Great Jagras, Kulu-Ya-Ku, Tzitzi-Ya-Ku, Great Girros, Dodogama, Leshen, Ancient Leshen, Yian Garuga, Shara Ishvalda, Safi'jiiva, Raging Brachydios, Alatreon, and Fatalis.

In-Game Mechanics

Tempered monsters have a metallic sheen to their bodies, deal more damage, become enraged more often, enter powered-up states faster, and are resistant to Flash Pods. Tempered monster investigations can be unlocked by gathering traces of Tempered monsters and by breaking Tempered monster parts; these investigations have Feystones as special rewards. Scoutflies glow blue instead of green when tracking a non-Elder Dragon Tempered monster or finding a trace of one. The icons of Tempered monsters have a purple outline.

Practical Uses

Tempered monsters are necessary to get various types of items called Streamstones and Spiritvein Gems. Streamstones are obtained as rewards from High-Rank Tempered monster quests, while Spiritvein Gems are obtained from carves or shiny drops from Guiding Lands Tempered monsters. Streamstone Shards, Streamstones, and Gleaming Streamstones can be used to meld decorations and augment High Rank weapons, while Spiritvein Gem Shards, Spiritvein Gems, and Great Spiritvein Gems are used in augmenting Master Rank weapons and upgrading charms. Streamstones and Spiritvein Gems can also be used to unlock the limit of armor upgrades, allowing to increase their defense furthermore. Tempered monsters in the Guiding Lands drop special materials that are used in augments, charms, and some weapon upgrades.

Sullied Streamstones and Shining Streamstones can be appraised and they are converted into Warrior's Streamstones or Hero's Streamstones. Warrior's and Hero's Streamstones are used to augment fully-upgraded weapons; augments are special final upgrades for a weapon. There are five available options for HR weapons: Attack, Affinity, Defense, Slot Upgrade, and Health Regen. The amount of augments available depends on the weapon Rarity. Warrior's and Hero's Streamstones can be used to augment a specific pair of weapons classes: Sword (Great Sword and Long Sword), Blade (Sword and Shield and Dual Blades), Hammer (Hammer and Hunting Horn), Lance (Lance and Gunlance), Axe (Switch Axe and Charge Blade), Shaft (Insect Glaive and Bow) and Ranged (Light Bowgun and Heavy Bowgun).

List of Tempered Material Sources

This is a rough list of each Tempered material's sources, based on the rewards of their respective quests.

Arch-Tempered Monsters

Arch-Tempered Monsters (Japanese: 歴戦王) are even stronger versions of Tempered Monsters. They have a darker and more pronounced metallic sheen, have more health and deal more damage, sometimes have new behavior and attacks, and their icons' outlines are orange. So far, only Elder Dragons except Behemoth, Blackveil Vaal Hazak, Ruiner Nergigante, Safi'jiiva, Shara Ishvalda, Alatreon, and Fatalis are known to be effected by the Arch-Tempered State. Arch-Tempered monsters are event-exclusive and their quests reward more streamstones than Tempered monsters and special tickets to craft γ (gamma) armor sets and layered armor sets.
