How it plays
Throw things and see what happens, then learn exactly what happens. Every substance you leave on the ground reacts with the next. Be the frantic field medic as the Apothecary, set off whole chains as the Volatilist, or drink the formula and wade in with claws as the Mutagenist.
Fights with flasks, satchels. Wears leather.
Every Alchemist has
The core kit, whichever Path you take.

FirebombOne vial of liquid fire: it bursts where it lands, sets everything in the blast burning and leaves the ground on fire for 3s. Your next thrown vial comes at once and ignites what it lands on. Fire sets your substances off: gas Explodes, a Poison Cloud becomes a Toxic Blast, healing liquid boils into Steam.

Volatile GasThe fuel: one vial of choking gas hangs over the ground for 8s, slowing and choking whoever walks through it - weak on its own, but light it and it goes up. Fire makes it Explode, acid turns it into a Poison Cloud, and healing liquid into an Anaesthetic that puts enemies to sleep.

Blast JumpSmash a vial at your own feet and ride the blast: you are blown 3 tiles away from your enemy, and the spot you left bursts into flame and stays on fire for 3s. The fire sets off any gas lying there.

Reagents PassiveFlasks cost vials: 6 in your satchel, one back every 6s in a fight. Every substance of yours that burns out or reacts leaves Residue: walk over it for a vial and 4% of your health. Your own healing liquid heals you at 40%, and your own explosions hit you for 50% (they never kill you).
Three Paths to choose between
Each Path adds three spells and a passive of its own. You can change it later at a trainer.
Apothecary
Healer
A frantic field medic: medicine thrown on the move, fire into the healing liquid for Steam, and a syringe for whoever is dying.
Healing Flask
Emergency Injection
Panacea
Field Medicine Your vials come back every 4s in a fight, and Residue of healing liquid returns 2. Reactions with healing liquid (Steam, Anaesthetic, Salt Glass) are 50% stronger. Your heals are 10% and your damage 20% stronger.
Volatilist
Damage
A spectacular chain-reaction artist: gas and acid on the chase path, fire to light it, and the whole line goes up.
Acid Flask
Chain Reaction
Grand Explosion
Volatile Mixtures Your reactions spread: an Explosion, a Poison Cloud or a Toxic Blast leaps to every substance of yours lying beside it and sets it off too. Your reactions hit 30% harder, your fire damage is 10% higher and all your damage 15% higher.
Mutagenist
Damage
A monstrous experiment: saturate them with toxin from range, spill mutagen under the pack, then drink the formula and wade in with claws.
Leech Toxin
Mutagenic Spill
Unstable Transformation
Saturation Your thrown vials (your auto attack) saturate what they hit with a dose of Leech Toxin. Blows on a saturated enemy heal the most injured ally near the one who struck. While transformed your own explosions cannot touch you. Your damage is 15% higher.
Knacks, small extras any Alchemist can pick: Smoke Flask, Quaff, Homunculus.
