Potion, rare

This sticky red liquid has a living viscosity to it, churning slowly within the flask. When you drink this potion, you become a fiend (as if by the spell shapechange for one hour.) The type of fiend you become is determined by your level. The new form is a random fiend ith a Challenge Rating equal to your level, up to a maximum of 10. If there are multiple options at that Challenge Rating, roll to determine which option is selected.

When the effect ends and you revert to your normal form, you take 1d6 necrotic damage equal to the CR of the fiend whose form you assumed as the toxins of pure evil attempt to destroy your body before relinquishing control of it. If this damage kills you, your soul is dragged to the realm of the fiends by the malignant will of the fiend.

Potion, legendary

When you drink this potion, you regain all lost hit points, all status effects are removed, all reductions to ability scores are removed, any missing limbs are restored, all diseases are cured, all curses are removed, and all levels of exhaustion are removed, and you cease to age for 1 year. This potion can remove effects that can otherwise only be removed by wish.

If you ever drink a second panacea potion, make a DC 30 Constitution saving throw. On failure, you gain no benefits from it and die.

Concoction, common

A small flask of burbling acid, a strange hissing green viscous liquid. It deals 4d4 acid damage when poured on an object. Can be used as a simple ranged weapon with the thrown (20/60) property, dealing 4d4 acid damage on hit. You do not add your modifier to the damage roll.

Concoction, common

A small flask of volatile orange liquid. It deals 2d10 fire damage when poured on an object. Can be used as a simple ranged weapon with the thrown (20/60) property, dealing 2d10 acid damage on hit. You do not add your modifier to the damage roll.

Concoction, common

A vicious sticky flammable substance. It deals 3d4 fire damage when poured on an object. Can be used as a simple ranged weapon with the thrown (20/60) property, dealing 3d4 fire damage on hit. You do not add your modifier to the damage roll.

On hit, the target creature or object continues to burn for one minute, taking 1d4 fire damage at the start of their turn (or at the start of your turn for an object without a turn) until a creature spends an action to put the flames out.

Concoction, common

As an action, you can open this casting gust without verbal or somatic components. Alternatively, you can breathe from it, letting out only a little bit at a time, breathing directly from the bottle, but each time you must make a DC 5 Athletics check. On failure, you cast gust as above and all the air is lost. You can get 10 minutes of breathable air from one bottle.

Concoction, rare

Drinking this potion allows you to zip around for 1 minute as pure electricity. As a bonus action on each of your turns before the effect ends, you can transform into a bolt of lightning and instantly travel in a straight line to an unoccupied space you can see within 30 feet. This movement doesn't provoke opportunity attacks and you are immune to lightning damage while in this form.

You can pass through small holes, narrow openings, and even mere cracks, as well as through conductive materials such as metal. Each creature in your travel path must succeed on a DC 15 Dexterity saving throw, or take 3d6 lightning damage. You immediately revert to your normal form upon reaching the destination. This potion's stormy liquid arcs with tiny bolts of lightning and it numbs the tongue when sipped.

Concoction, common

When broken and exposed to air, it creates a very sticky, rapidly expanding weblike foam, with the effects of the spell web centered on where the flask breaks. You can reliably throw the flask to a target point within 30 feet, shattering it on impact.

Oil, common

As an action, you can coat a weapon in this oil and ignite it. For 1 minute, the ignited weapon burns, dealing an extra 1d4 fire to attacks made with it, and providing bright light in a 20-foot radius and dim light for an additional 20 feet.

Oil, common

As an action, you can coat a weapon in this oil, causing it to freeze over, covered in icy crystals. For 1 minute, the weapon deals an extra 1d6 cold damage on hit.

Oil, uncommon

As an action, you can coat a weapon in this oil and ignite it. For 1 minute, the ignited weapon burns, dealing an extra 2d6 fire to attacks made with it, and providing bright light in a 20-foot radius and dim light for another 20 feet.

Oil, common

A sparkling chromatic oil. The oil can coat one slashing or piercing weapon or up to 5 pieces of slashing or piercing ammunition. Applying the oil takes 1 minute. For 1 hour, the coated item is considered silvered.

Explosive, common

A fine grey powder with large grains and the faint smell of sulfur and charcoal that comes in small packets weighing 1/2 pound.

When ignited by 1 or more fire or lightning damage, it explodes violently. All creatures within 10 feet of it must make a DC 14 Dexterity saving throw. On failure, they take 1d4 fire + 1d4 thunder damage, or half as much on a success. The amount of damage increases by 1d4 (both the fire and thunder) and the radius increases by 5 feet for each additional packet of Blasting Powder detonated in the same spot, up to a maximum of five packets. Deals double damage to buildings and structures. Creatures in range of more than one stack of up to 5 explosives at the same time take damage only from the highest damage effect.

Frequently used for mining and other responsible things… until adventurers get their hands on it.

Explosive, common

Only dwarves really know if the name of this liquid explosive is a joke or not, but one must assume it is an acquired taste. An explosively flammable liquid that comes in a flask, this flask can be splashed across a 5 foot square within 5 feet. Once splashed, it can be ignited by 1 or more fire or lightning damage. When ignited it explodes in a plume of fire, dealing 2d4 fire damage to all creatures within 5 feet of the container, or within a square that has been soaked with it.

Explosive, uncommon

A simple construction of a two chambered projectile (typically made of glass.) When you add an Alchemist Fire and an Explosive to its separate compartments, it becomes an incredibly dangerous device. As an action, a character can light this bomb and throw it at a point up to 60 feet away. Creatures within the range of the explosive used must make a Dexterity saving throw against the DC of the explosive used, or take damage equal to the explosion + 1d4 piercing damage + 1d4 fire damage.

Explosive, uncommon

A brutal instrument, this mixes explosive powder and nails to create a devastating fragmentation device. An exceedingly dangerous device. Heavier and more deadly than other explosives, the primary damage comes from the metal shrapnel (nails) flung in all directions. It can be detonated by dealing 1 fire or lightning damage to it. As an action, a packet of this explosive can be accurately thrown 20 feet, but will not detonate on impact (usually). When it detonates, all creatures within 20 feet of the target point must make a Dexterity saving throw with a DC equal to the crafter's Alchemy DC. On faiure, they take 8d4 piercing damage, or half as much on a success.

You can fuse your explosives. When fused, intentionally dealing fire damage to the explosives (or otherwise lightning the fuse) causes it to detonate on a delay, selected from: short (the end of your turn), medium (the start of your next turn), and long (2 rounds, at the start of your turn.)

Explosive, common

A fine grey powder with large grains and the faint smell of sulfur and charcoal that comes in small packets weighing 1/2 pound.

When ignited by 1 or more fire or lightning damage, it releases a blast of thick black smoke that fills a 20-foot radius. Everything in this smoke is heavily obscured for 2d4 rounds. At the start of your next turn after the number of rounds rolled, the smoke begins to fade leaving everything within the radius lightly obscured, and it clears completely at the start of your next turn after that.

Additional uses of the smoke powder extend the duration of heavy obscurement for an extra 1d4 rounds.

Explosive, common/uncommon/rare

A bundled explosive alchemical preparation. It can be detonated by dealing 1 fire or lightning damage to it. As an action, a packet of this explosive can be accurately thrown 20 feet, but will not detonate on impact (usually). When it detonates, all creatures within 10 feet (for common) of the target point must make a Dexterity saving throw with a DC equal to the crafter's Alchemy DC. On failure, they 1d8 fire + 1d8 thunder damage, or half as much on a success. Creatures in range of more than one explosive take damage only from the highest damage effect.

You can fuse your explosives. When fused, intentionally dealing fire damage to the explosives (or otherwise lightning the fuse) causes it to detonate on a delay, selected from: short (the end of your turn), medium (the start of your next turn), and long (2 rounds, at the start of your turn.)

Component, common/uncommon/rare/very rare/legendary

Magical ink that is used by Enchanters to create scrolls, made by rendering down magical alchemical ingredients.

The following are alchemical modifiers that can be applied to a potion. All alchemical modifiers require approval from the GM if the modifier will work with a given potion or creation.

You can simply load more reagents into any potion, increasing its potency in different ways, though it increases the difficulty. You can make a 'custom potion' simply by using these modifiers with no base potion. When you do so, the base DC is 8.
