Eternal Elixir
Level 16 Alchemist

Prerequisites: Extend Elixir

Your body readily accepts and retains minor changes. When you drink one of your alchemical items that has the elixir and infused traits and a duration of 1 minute or more, you can make the elixir’s duration indefinite. You can do so only if the elixir’s level is half your level or lower. If you later consume a different elixir and make it indefinite, the effect of the previous indefinite elixir ends.

Exploitive Bomb
Level 16 Alchemist Additive 2

Trigger: You craft an alchemical bomb using Quick Alchemy that’s at least 2 levels lower than your advanced alchemy level.

You mix a substance into the bomb to foil resistances. The bomb reduces any resistance the enemy has to its damage type by an amount equal to your level, but only for that attack.

Genius Mutagen
Level 16 Alchemist

Specialized tweaks to your formula that supplements your genius considerably broaden the benefits you gain from cognitive mutagens. When you’re affected by a cognitive mutagen you created, you also gain the mutagen’s item bonus to Deception, Diplomacy, Intimidation, Medicine, Nature, Performance, Religion, and Survival checks. In addition, you can communicate telepathically with creatures within 60 feet with whom you share a language. The communication is two-way once you establish it, so a creature you contact can also communicate with you.

Persistent Mutagen
Level 16 Alchemist

Prerequisites: Extend Elixir

You’ve trained your physical form to remain stable within the a given altered state. Once per day, when you consume an alchemical item with the infused and mutagen traits that you have crafted, you can retain its effects until the next time you make your daily preparations instead of its normal duration.

Improbable Elixirs
Level 18 Alchemist

Your mastery of alchemical secrets enables you to replicate effects most believe can be achieved only via magic. Select a number of potions equal to your Intelligence modifier (minimum 1) of 9th level or lower. You gain formulas to Craft these potions as alchemical items with the elixir trait. When Crafting these alchemical elixirs, you can substitute alchemical reagents for an equal value of magical components, and you can use alchemist’s tools instead of any other required tool kits. Other than that, the formula does not change. Once you’ve chosen the potion formulas, they can’t be changed.

Mindblank Mutagen
Level 18 Alchemist

With a minor adjustment of ratios in the formula for your serene mutagen, you gain mental protections. When you’re affected by a serene mutagen you created, detection, revelation, and Scrying effects of 9th level or lower detect nothing from you or your possessions and auras. For instance, detect magic would still detect other magic in the area, but not any magic on you.

Miracle Worker
Level 18 Alchemist

Your alchemical mastery can resuscitate the recently slain.

You can administer a true elixir of life to a creature who has been dead for no more than 2 rounds. When you do, that creature is immediately returned to life with 1 Hit Point and becomes wounded 1.

Perfect Debilitation
Level 18 Alchemist

You have perfected the formulas for bombs that impede your enemies. When you use Debilitating Bomb, your target avoids the condition the bomb imposes only if it critically succeeds at its saving throw.

Craft Philosopher’s Stone
Level 20 Alchemist

Your research has paid off, culminating in the legendary philosopher’s stone. You learn the formula for the philosopher’s stone and can add it to your formula book.

Mega Bomb
Level 20 Alchemist

Prerequisites: Expanded Splash

You add an incredibly powerful additive to a held bomb to create a mega bomb, greatly increasing its area and power.

You use an Interact action to throw the mega bomb, rather than Strike, and you don’t make an attack roll. The mega bomb affects creatures in a 30-foot-radius burst, centered within 60 feet of you. The bomb deals damage as if each creature were the primary target, with a basic Reflex save.

On a failed save, a creature also takes any extra effects that affect a primary target (such as flat-footed from bottled Lightning). While all targets in the area take splash damage as primary targets, there is no further splash beyond that area. If your next action after creating a mega bomb isn’t an Interact action to throw it, the mega bomb denatures and loses all effects.
