Plague Warden

Some rangers devote themselves to protecting society from the ravages of contagious disease and poisonous pollutants. Known as plague wardens, such rangers use their martial prowess to fight against disease-spreading monsters and those who would poison the world, augmenting their fighting with miasma absorbed from the air. They use their skills to cure those afflicted by toxins and brew poisons to wield against their enemies.

Plague Warden Magic

Starting at 3rd level you learn an additional spell when you reach certain levels in this class, as shown in the Plague Warden Spells table. If the table lists multiple spells for a leveL you choose only one of them to learn. The spell counts as a ranger spell for you, but it doesn't count against the number of ranger spells you can know. These spells can't be replaced when you gain a level in this class, but instead you can change your decision for one level on the table.

Ranger Level	Spells
3rd	purify food and drink, spasm
5th	lesser restoration
9th	plague vector, stinking cloud
13th	envenomed weapon
17th	cloudkill, contagion

 

Miasma Infusion

At 3rd level you gain the ability to infuse your weapons and magic with noxious miasma. On your tum, when you hit a creature with a weapon attack or deal a creature poison damage or necrotic damage, you can cause the attack or effect to deal ld6 bonus poison damage. If the creature is immune to poison damage, this feature adds ld4 necrotic damage instead, or ld6 necrotic damage if it is among your favored enemies. You cannot use this feature more than once per tum.

Plague Doctor

Also at 3rd level, you become preternaturally aware of the presence and nature of toxins. You gain proficiency in the Medicine skill, in herbalism kits, or in poisoner's kits (your choice). You can also cast detect poison and disease as a ranger spell without expending a spell slot or requiring components.

You can use this feature to cast the spell a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Herbalism Kit Proficiency

You gain proficiency in herbalism kits.

Medicine Skill Proficiency

You gain proficiency in the Medicine skill.

Poisoners Kit Proficiency

You gain proficiency in poisoner's kits.

Toxin Tolerance

Starting at level 7, you gain resistance to poison and necrotic damage, and you have advantage on saving throws against poison or disease. You are also immune to the effects caused by any stench or bad smell such as the stinking cloud spell

Infectious Corruption

At 11th level you learn how to spread miasma from foe to foe, increasing its power as it spreads. When you deal damage to a creature using your Miasma Infusion feature, you can also deal ld8 poison damage to up to two other creatures of your choice within 15 feet of the target. If a creature is immune to poison damage, it takes ld6 necrotic damage instead, or ld8 necrotic damage if it is among your favored enemies.

Fuming Wounds

Starting at 15th level your wounds and injuries give off noxious fumes that you direct. When a creature hits you with a melee attack, you can use your reaction to expose the attacker to these poisonous fumes. The attacker must succeed on a Constitution saving throw against your ranger spell save DC or become poisoned until the end of its next tum. If it can't be poisoned, its speed is reduced by 10 feet for the same duration instead.
