Tonics are the special episodic mechanic for Destiny 2s episode Revenant, the second in Bungies post-Final Shape epilogue releases. These Tonics help you target certain gear pieces to farm (granting you bonus loot of your chosen type) and can also enhance your artifact perks for the season, making your build even more powerful. Unfortunately, it takes a lot of work and resources to unlock all of the Revenant Tonics.In this Destiny 2 guide, well walk you through how to unlock Tonics and give you a full list of all Tonics you can craft.How to unlock Tonics in Destiny 2Tonics branch off of each other, starting with uncommon, moving to rare, and then to Legendary. There are two Exotic Tonics you can craft, but you unlock the ability to do so by collecting the Intrinsic upgrades for the Slayers Fang shotgun in the Kells Fall Exotic mission.To unlock all of the Undiscovered Formula Tonics, you simply need to buy Tonics of a lower tier. Crafting five uncommon Tonics will unlock a rare Tonic in the same branch, and crafting four rare Tonics will unlock a legendary in the branch. The only catch here is that, for Tonics that have multiple branches you can unlock, youll gain access to a random Tonic every four or five that you purchase.For example, if you wanted to get bonus drops of the Gridskipper pulse rifle from Season of the Splicer, you might want to unlock the Tonic of Gridskipper in the Tomb Gear Tonic track. To do that, youd want to buy five uncommon Tonic of Tomb Gear potions. Doing this will randomly unlock either the Tonic of Tomb Weaponry or Tonic of Vintage Tomb Weaponry.For the sake of the example, lets say you unlocked the Tonic of Tomb Weaponry, which isnt the Tonic that Tonic of Gridskipper branches off. You need Tonic of Vintage Tomb Weaponry. To get what you actually want, youd need to craft five more Tonic of Tomb Gear potions to unlock the Tonic of Vintage Tomb Weaponry, and then craft four of those to unlock one of the three legendary Tonics that branch off it one of which is Gridskipper.If youre looking for a specific Tonic, its a bit of a luck of the draw system, where youll be gambling various resources (which you can learn about where to find via the Tonic Capsule in-game) until you get the Tonics you want. But if youre just looking to unlock all the Tonics to complete Eidos Fieldworks, just craft each uncommon Tonic until youve unlocked all the rares in that category, then craft each rare until youve unlocked all the legendary Tonics that stem off of them.Just a fair warning here that the rare resources will be your bottle neck in this process, as you need one for every rare Tonic you need to craft. Be prepared to play a lot of the Revenant activities if you want to unlock all of the Tonics.All Tonics list in Destiny 2There are two major categories for Tonics in Destiny 2: Volatile and Enriching. Volatile Tonics power up your artifact perks, while Enriching Tonics give you bonus chances for specific loot drops.Weve broken down the complete Tonics list and branches below.Volatile TonicsThere is only one category of Volatile Tonics, with each Tonic branch focused on two perks.Diluted Tonic of Protecting Frost -> Potent Tonic of Protecting Frost -> Refined Tonic of Protecting FrostDiluted Tonic of Stasis Crystallization -> Potent Tonic of Stasis Crystallization -> Refined Tonic of Stasis CrystallizationDiluted Tonic of Renewing Finishers -> Potent Tonic of Renewing Finishers -> Refined Tonic of Renewing FinishersDiluted Tonic of Weakening Void -> Potent Tonic of Weakening Void -> Refined Tonic of Weakening VoidDiluted Tonic of Amplified Arc -> Potent Tonic of Amplified Arc -> Refined Tonic of Amplified ArcDiluted Tonic of Brawling -> Potent Tonic of Brawling -> Refined Tonic of BrawlingDiluted Tonic of Void Shrapnel -> Potent Tonic of Void Shrapnel -> Refined Tonic of Void ShrapnelEnriching TonicsDrinking an Enriching Tonic will guarantee you a specific piece of gear or a piece of gear from a selected loot pool.
