History of Reagents

Reagents are crafting materials from Episode: Revenant that are used to brew tonics at the Tonic Laboratory for Apothecary Eido. Different reagents come from different sources.

Sources

• Most reagents drop from defeated enemies and from Revenant activities. Reclaimed Vitality also comes from destination materials.
• Onslaught: Salvation is the recommended farming route. It is launched from the Last City map in 10-wave or 50-wave versions and rewards reagents as well as Revenant gear. Volatile and Enriching reagents come from it, and higher difficulties improve the chance of Nugget reagents.
• Tomb Flake comes from Tomb of Elders and Contest of Elders. Reflective Flake comes from the Exotic mission Kell's Fall and from Tonic Reagent Sacks.
• Completing minor fieldwork from Apothecary Eido rewards Tonic Reagent Sacks, and Ingredient Bundles give varying amounts of reagents depending on their size.
• Dismantling Revenant gear can also yield reagents.

Use

Reagents are spent at the Tonic Laboratory to craft tonics. Only one Volatile Tonic and one Enriching Tonic can be active at a time, and consuming a new one replaces the effect of the previous one.

Notes

Reagent sources and tonic recipes were reported mainly during Episode: Revenant. They change with each season, so check the in-game Tonic Capsule for current sources.
