Alchemist

You have learned many things about alchemy during your studies. Starting at 1st level, you can add half your proficiency bonus, rounded up, to all skill checks made to identify herbs, potions, poisons, or other alchemical substances. If you are proficient with such a skill, this bonus stacks with your normal proficiency bonus.

Starting at 1st level, you can create volatile alchemical bombs using your alchemist's supplies and material components. The cost of materials necessary to create these bombs is negligible, but you must have alchemist's supplies and a component pouch on hand to create anything. After 24 hours, an unused bomb becomes inert.

You are proficient with your bombs and can't throw more than 1 bomb per round. You do not have disadvantage when throwing a bomb while within 5 feet of a hostile creature. If you miss your attack roll with a bomb, the bomb does not explode. When a creature without proficiency with bombs makes an attack roll with one, there is a 50% chance that the bomb detonates before being thrown, dealing full damage to the attacker.

Your bombs are finesse thrown weapons with a range of 30/60 feet. Unlike other thrown weapons, you add your Intelligence modifier to damage, rather than Strength or Dexterity. On a hit, the target takes 1d10 fire damage and each creature within 5 feet of it must succeed a Dexterity saving throw or take half as much damage. You can also choose to throw a bomb at an empty space within range, which is considered to have an AC of 10.

The amount of damage dealt by your bombs increases as you gain levels in this class, as shown in the Bomb Damage column of the Alchemist table.

Beginning at 2nd level, your research has granted you insight into new formulae for your bombs. Select three bomb formulae from the "Bomb Formulae" section below. You can apply a formula to one of your bombs when you make an attack with it. When you gain certain levels, you learn additional formulae of your choice, as shown in the Bomb Formulae Known column of the Alchemist table.

Additionally, when you gain a level in this class, you can choose one of the formula you know and replace it with another formula.

While all alchemists share a common knowledge base, most alchemists specialize into a particular field of study. When you reach 3rd level, you select your field of study. Your field choice grants you features at 3rd level and then again at 7th, 10th, and 17th level.

When you reach 4th, 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

At 4th level, you can use your bonus action to surprise a creature within 10 feet with a small mundane explosive. The creature can't take reactions until the start of its next turn.

In the course of your research, you have made a number of discoveries regarding the nature of alchemy. At 5th level, you gain two discoveries of your choice. When you gain certain alchemist levels, you gain additional discoveries of your choice, as shown in the Discoveries Known column of the Alchemist table.

Additionally, when you learn a new discovery, you can choose one of the discoveries you know and replace it with another discovery that you could learn at that level.

At 6th level, you learn to create magical potions with ease and speed. You have a number of alchemy points equal to half your alchemist level (rounded up). During a long rest, you can brew potions by expending these points. You regain all expended alchemy points when you finish a long rest. The potions retain potency 24 hours, after which they become inert.

You can brew potions of climbing, growth, healing, and water breathing for 1 alchemy point each. At 9th level, you can brew potions of heroism and resistance for 2 alchemy points each and at 14th level you can brew potions of invisibility and speed for 3 alchemy points each.

When you reach 8th, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

At 9th level, you can brew potions of heroism and resistance for 2 alchemy points each

When you reach 12th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Beginning at 13th level, your experience with avoiding your own bombs' explosions has granted you the ability to nimbly dodge out of the way of certain area effects, such as a red dragon's fiery breath or an ice storm spell. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

At 14th level you can brew potions of invisibility and speed for 3 alchemy points each.

When you reach 16th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

When you reach 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

At 20th level, you unlock the secrets of alchemy. Using your alchemist's supplies and 1000 gold pieces worth of materials, you can spend 1 week of work creating a philosopher's stone, a dynamo of elemental energy encased in a fist-sized, glowing jewel. Your philosopher's stone only works in your possession, and you can only have 1 at a time. To any other creature, it is just an ordinary (if beautiful) gemstone. As long as you possess your philosopher's stone, you gain the following benefits.

The philosopher's stone also has devastating destructive potential. As a bonus action when you throw a bomb, you can replace its reagent with the philosopher's stone, creating a nuclear bomb. A nuclear bomb has a blast radius of 500 feet, dealing 10d10 + 50 damage to all creatures in the area.
