Poison

Poison is meant to weaken, sicken, and kill. The Poison theme focuses on poisons, poison damage, and debuffs, with some utility and protection related to poisons.

Spells from the Poison theme allow you to intoxicate creatures, release toxic fumes, detect poison, protect creatures from poison, putrefy water and food, sicken creatures, and create clouds of poisonous and nauseating gas.

Poison feats

You can take each feat only once, unless the feat’s description says otherwise. You must meet any prerequisite specified in a feat to take that feat. If you ever lose a feat’s prerequisite, you can’t use that feat until you regain the prerequisite.

Prerequisites: The ability to create a concoction or cast a spell that deals poison damage

When you roll a 1 on a damage die for a concoction you created or a spell you cast that deals poison damage, you can reroll the die and must use the new roll, even if the new roll is a 1.

If you, or parts of your body, are ingested by a creature, the creature must succeed on a Fortitude saving throw or be poisoned for 1 minute. Each turn while poisoned from you, the creature takes damage equal to your level + your Constitution (minimum 1). The poisoned condition ends if the creature regurgitates you or your body parts.

You have advantage on saving throws against poison and advantage on saving throws against being poisoned.

Prerequisites: Poison Adept feat

Spells you cast and concoctions you create ignore resistance to poison damage.

You can detect poisons as the detect poison spell at will, without casting the spell or expending mana.

Poison concoctions

1 hour/catalyst

As an action, you can create a vial of foul-tasting, milky tonic. A creature can drink the contents as an action to have advantage on saving throws against being poisoned, and have resistance to poison damage for the duration.

If it is poisoned, the poison is neutralized. If more than one poison afflicts the target, a random poison is neutralized.

Augment

Immunity. You can expend 2 additional catalysts so the creature is immune to the poisoned condition and poison damage.

unstable, 10 minutes/catalyst

As an action, you can create this poisonous oil. As an action, a creature can coat one weapon with the oil to cause it inject poison into creatures it hits. For the duration, the weapon deals an extra 1d6 poison damage when it hits.

Alternatively, you can touch a quiver containing arrows or bolts, granting the ammunition pulled from it the same effect. The oil’s effect ends on a piece of ammunition when it hits or misses.

Augment

You can increase the damage by 1d6 for each additional catalyst expended and an additional 1d6 for every other additional catalyst expended.

As an action, you can create a packet of fine gray powder. As an action, a creature can throw the packet at a point within 9 meters, where it bursts on impact. Each creature in a sphere twice as big as normal centered on that point must succeed on a Fortitude saving throw or be affected for 1 minute. An affected creature has disadvantage on attack rolls and ability checks.

A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

1 day/catalyst

On a failed save, a creature smells like weak prey to predators. Creatures can smell a marked creature at five times the normal range. If they smell it, they can note its direction, pinpoint it when it is within 9 meters, and track it by scent with advantage on its ability checks. Immersion in water within 1 round of exposure washes it off; otherwise the effect decreases by one range increment per day (four times normal range after 1 day, three times range after 2 days, and so on) until the creature is again at normal scent levels.

1 hour/catalyst

As an action, you can create a vial liquid with white powder that has green pieces suspended in it. A creature can drink the contents as an action to have advantage on saving throws against being poisoned, and resistance to poison damage for the duration.

1 minute/catalyst
