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.

You can maintain a spell with hardly a thought. You immediately gain the effects of a Sustain a Spell action, allowing you to extend the duration of one of your active bard spells.
Studious Capacity
Level 16
Bard
Prerequisites: Enigma Muse, Legendary in Occultism
Your continued study of occult magic has increased your magical capacity, allowing you to cast spells even when it seems impossible. You can cast one spell each day even after you've run out of spell slots of the appropriate spell level, but you can't use this ability to cast a spell of your highest spell level.
Auspicious Mount
Level 16
Champion
Prerequisites: divine ally (steed), Imposing Destrier
Guided by your ongoing care, your steed has developed incredible intelligence and skill. The mount you gained through the divine ally class feature is now a specialized animal companion (page 217). You can select one of the usual specializations or the auspice specialization.
Auspice mounts gain the following benefits: Your companion is marked by your deity’s religious symbol as a sacred creature of your deity. Its proficiency rank in Religion increases to expert, it can speak the language associated with your deity’s servitors (Celestial for champions who follow the tenets of good), and its Intelligence modifier increases by 2 and its Wisdom modifier by 1.
Instrument of Zeal
Level 16

Prerequisites: divine ally (blade), tenets of good

Shield of Grace

Prerequisites: Shield Warden
You protect an ally with both your shield and your body. Whenever you use the Shield Block reaction to prevent damage to an ally, you can evenly split the remaining damage after the Shield Block between the ally and yourself.
Eternal Bane
Level 16
Cleric
Prerequisites: evil alignment
A life of evil has made you a nexus for your deity’s vile power. You’re continuously surrounded by a bane spell with a spell level equal to half your level (rounded up). The radius is 15 feet, and you can’t increase it. You can Dismiss the spell; if you do, it returns automatically after 1 minute.
