The Poisoner Class for Dungeons & Dragons (D&D) Fifth Edition (5e)

Base Class: Rogue

as a poisoner rogue, you will obtain a mechanic known as toxin die in order to craft a number of toxins that may be inflicted upon your enemies in a wide variety of ways. some of your toxins are simply and just poison your opponent and deal damage, others linger into your opponents mind and essentially blind them. whether it be by exposing yourself to poison constantly to gain immunity, or studying your opponents until the end of the earth. ultimately this class offers a decent subclass built round the poisoner feat in order to bring forward a new approach to poisonous and toxic substances in general.

Poison Crafter

you gain access to a pool of toxin dice. These toxin dice are treated as the ingredients to make your toxins. Your toxins are treated as non-magical and require expanding an amount of toxin dice equal to its cost and at least 1 hour of downtime to create.

In addition, your toxins are all injury poisons unless stated otherwise.

Toxin dice are represented by the following table

When you make a damage roll, you ignore resistance to poison damage.

You can coat a weapon or 5 pieces of ammunition in poison as a bonus action, instead of an action.

You gain proficiency with the poisoner's kit if you don't already have it. With one hour of work using a a number of toxin die as stated for each toxin individually (which your toxin dice can be attained by buying 50 gp worth of materials per dice, or by spending a short rest looking for materials in the wild, however this requires a Wisdom (survival) check, on a 1-5 you gain no toxin die, and a 6-10 you gain 1 toxin die, on a 11-15 you gain 2 toxin die, on a 16-20 you gain 4 toxin die, and on any number above 20 you simply gain all your toxin die back, you cannot go looking for materials more than once per day, all your toxin die also reset on a long rest), when you sit down for a hour to create a toxin, you can choose to create a number of toxins equal to or less than your proficiency bonus, however you still have to expend toxin die in order to make these, (such as if i am spending a hour making 2 “debilitating” toxins, it will still cost me 4 toxin die but no additional hours of work). Once a toxin is applied to a weapon or piece of ammunition, the poison retains its potency for 1 minute or until you hit with the weapon or ammunition a number of times equal to your proficiency bonus. You cannot have more than one toxin applied to a weapon at any given time.

infectious strike

your understanding of creatures' bodies and exactly how your toxins affect them have caused you to know exactly where to hit to inflict the most pain. You can now apply sneak attacks to anything affected by your poisons.

Toxic exposure

your constant exposure and understanding of your own toxins has begun to limit what substances of a poisonous nature can do to your body. You are now immune to the “Poisoned” condition, and all poison and psychic damage you receive is halved.

Perfect Application

You have mastered the art of applying poisons to your weapons. You can now apply up to 2 toxins at the same time to a weapon now instead of just 1.

In addition, once you’ve applied your toxins to a weapon that you're proficient in, that toxin is so potent that it remains with the weapon even after it's dried and the toxin won't wear off until you remove it. When a creature is hit with a 2 toxin weapon, the effects are treated as happening at the same time.

When making your toxins they do not have to be just injury anymore, you can now make your toxins in the form of ingested, inhaled, or contact poisons as well.

Finally, you have advantage on checks to apply poisons elsewhere, such as in food with ingested toxins for example.

Deteriorating poisons

At 17th level, your constant exposure to the creatures of the world has lead you to realize most things of a higher caliber are not affected by your brews, thus you have spent so much time analyzing creatures that are immune to your toxins that you have perfected the crafting of your toxins to defy creatures that would have laughed in your face when presented with your creations. Any creature that has immunity to psychic or poison damage when you attack it is treated as having resistance, any creature that has resistance to psychic damage is treated as not having so.

LIST OF TOXINS

The amount of damage your toxin’s deal is equal to the amount of toxin dice associated with them.

In addition, your toxin’s can stack with each other but again you cannot have more than 1 toxin applied to 1 weapon.

In addition, creatures that are immune to poison damage are immune to these effects at all, unless otherwise stated by another ability.

Lastly, each of these concoctions are unstable and after 1 day has passed, they go inert returning to the base toxin solution mixture that works as a baseline for creating any toxin.

MASTERCRAFTED TOXINS

In order to create a master crafted toxin you must spend 50gp worth of materials and a short rest and expended the appropriate amount of toxin die associated with it. For master crafted toxins, their abilities cannot stack, whether it be with themselves or others, a creature can only be affected by 1 master crafted poison at a time. A creature affected by a master crafted toxin repeats the saving throw at the beginning of each of its turns until accumulating either 3 successes or 3 failures. If 3 successes happen the creature is immune to the master crafted toxin for 1 day. However, it can still take the poison damage as per usual. If 3 failures occur however, the effect becomes permanent, and each master crafted toxin has a correlating effect for what happens if the effect becomes permanent.

NAME OF TOXIN	NUMBER OF TOXIN DIE REQUIRED TO MAKE	DESCRIPTION: for each of these toxins, they will have to make a saving throw with a DC of (8 +your proficiency bonus + your wisdom modifier) the targets take half damage on a successful save.

Antidote	Equal to the associated poison	When making this poison you must choose one of your other toxins to base your antidote off, that toxins toxin dice is how many toxin dice you need to expend to make the antidote. When you are subjected to a poison, you can use your reaction and expend one antidote to have a bonus on your saving throw against the poison by the number you roll on the toxin dice used to make the antidote, and reduce the poison damage by the same amount. Your antidote also fully neutralizes the effects of 1 toxin that you base it off and can be given to another creature for them to imbibe.

When a target takes damage from this toxin, if it is the associated creature type all dice are doubled to 16 rather than 8. The target affected by this poison must make a CON save to take half damage.

Toxic Blood

At 17th level, your time with poison has changed your biology, and your wounds and injuries give off noxious fumes and toxic blood. when a creature hits you with a melee attack, you can use your reaction to expose them to your toxic innerworkings. The target must succeed on a CON save equal to your Toxin save DC or become poisoned until the end of its turn, and if the target is immune to poison you can spray your acidic blood over the targets armor and weapon, giving them a -1 to AC and -1 to the damage their weapon wields if these penalties go to -5 the weapon or armor is destroyed. You are resistant to all damage that attack does
