Ingredient Substitution[edit]

At first level, when Brewing a Potion, you may substitute one ingredient per potion. You can only do this if the ingredient is the same type, is of equal or more value, and of equal or more rarity.

Poison Novice[edit]

At 1st level you become proficient in brewing poisons. It takes a fourth the cost of the poison in ingredients to make poisons for you and you only need to spend a fourth the time it would take to make a full poison (ex. Assasin's blood costs 150 gp, most people have to use 75 gp worth of ingredients and would take 30 days to create the poison. You only need 19 gp of ingredients and 8 days to create the poison and on that 8th day you can start making a new poison). You also add your proficiency modifier to the DC of any poison you have studied. You have a journal in which you contain the poisons you are competent with starting with Assassin’s Blood and Serpent Venom and any other poisons you work out with the DM. You are also allowed to your medicine skill in using Poisoner’s kit rather than intelligence if you choose. Poison is a loose term you can also create acids if you have the right items.

Proficient Harvester[edit]

At 2nd level you are now quite focused at harvesting new items for poisons. You may use a medicine rather than nature roll for these types of effects. You may also roll a DC 20+ ½ creature CR – proficiency – wisdom modifier to attempt to know the weak points of a creature. If so you have advantage on attacks against the creature.

Poisoner Archetype[edit]

At 3rd level, you chose a poisoner archetype. Choose between a crafty Intelligent Disperser, the cruel Reaper,the skilled Monster Harvester or the versatile Medical Adept, all detailed at the end of the class description. Your choice grants you features at 3rd and again at 6th, 11th, and 17th.

Ability Score Increase[edit]

When you reach 4th level, and again at 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.

Poison Apprentice[edit]

At 5th level you can craft 25 gp worth of poison a day. Poisons you create also have 2 extra die worth of damage (poisons that due no damage naturally gain 2d6) and if unnoticed the victim has disadvantage on the save. You may analyze poisons you haven’t made in order to learn an ingredient of the poison. This consumes a dose of the poison.

Dirty Fighting[edit]

Weapons you use at 7th level that are poisoned have an extra d6 of damage and retain 1d4 +proficiency uses of poison rather than just a single use.

Poison Adept[edit]

At 9th level you can make 50gp worth of poison a day and use only a fifth the ingredients. Poisons you create gain another 2 die of damage. You may alter poisons you haven’t made to add 2 die to the damage. You may perform 2 analysis of poisons you haven’t made. The second analysis consumes the poison.

Adaptive Poisons[edit]

At 10th level you get the ability to create poisons that have different up take techniques from the usual. You and the DM will need to discuss the effects these changes will have on the poison (ex. Injury based assassin’s blood may need to deal less damage.)

Poison Expert[edit]

At 13th level your poisons become very effective against almost all creatures. All poisonous attacks you make against anyone or anything that creature must make a DC16 constitution saving throw or take double damage. You also are able to poison weapons in the middle of combat as a bonus action.

Powerful Poisons[edit]

At 14th level you create such powerful poisons that creatures with a physical form that are normally immune to poison only have resistance to them and creatures with resistance have none. This does not apply to items and only to the damage type poison.

Ingredient Substitution[edit]

At 15th level your intensive study on different ingredients has allowed you to find combinations of ingredients that can substitute more expensive ingredients in poisons. This makes the poison less potent but can greatly reduce the cost of creation of the poison.

Taste of your own medicine[edit]

Starting at 17th level any poison that you are affected by has the opposite effect depending on the poison. You are also able to convert other potions into deadly poison. For all poisons you are affected by the constitution saving throw is subtracted by your proficiency + your constitution modifier.

Death Drink[edit]
