Dark Arts Militant

Bonus Proficiencies

Starting at 3rd level, your curiosity for the dark arts and using them in practical ways grant you some abilities. You gain proficiency with alchemist’s supplies, and you learn to speak, read, and write Abyssal and Infernal.

Dark Artist

Starting at 3rd level, you learn how to craft oils and poisons by using the knowledge on the forbidden arts that you have uncovered so far. When you gain this feature, you learn the recipes of one dark oil and one dark poison (see Recipes of Dark Oils and Recipes of Dark Poisons).

Additionally, each time you gain a feature of this archetype, you uncover the recipes of one more poison and one more oil.

You prepare each oil or poison in 10 minutes by using the needed materials and tools. The materials cost 50 gp to prepare a dark oil or a dark poison. Once it is prepared, the quality of an oil or a poison stays intact for 24 hours, after which point, it loses all of its properties and turns into a useless liquid.

As an action, you can use a dark oil or a dark poison. You can also clear them from the applied surface as an action. When cleared, the effects created by the liquid end. However, if the liquid is ingested, it needs to be vomited out to end its effects.

The oils and poisons that you prepare are highly dangerous and profane chemicals. So, it is risky to use them frequently. Once you drink a dark oil or apply it on your body, you can only do so again without harm after you finish a long rest. You suffer one level of exhaustion each time you use the same oil again before finishing a long rest. Due to these recipes’ magical origins, the toxic chemistry of the oils still affects you even if you are immune to being poisoned and exhaustion.

When you apply a dark oil or a dark poison on an item and use it, the applied chemicals leave a residue on the item. If you try to apply the same oil or poison on the same item again before finishing a long rest, the residue builds, harming the item and lowering its quality. Each time the same chemical is used on the same item after the first, the damage it deals takes a -1 penalty, and the item is broken when the penalty reaches -4. The damage that causes the -1 penalty can be repaired in 1 hour by using smith’s tools.

If a dark oil or a dark poison requires saving throws, the DC equals 8 + your proficiency bonus + your Intelligence modifier.

When a dark oil or a dark poison is used, its effects last 1 minute.

Roleplaying Tips

Dark Arts Militants are knowledgeable warriors who constantly search for dark secrets. Although the archetype is oriented around dark powers, do not forget that they are a fighter after all. They seek knowledge, but they seek that which they can use in combat.

Working on recipes, gathering components, and brewing chemicals are important parts of their life, but fighting techniques and martial tactics are also important. A poison is nothing without the blade they infuse it with…

Tools of a Dark Artist

Starting at 7th level, your magical secrets, your dark oils and poisons can make a weapon magical and you have a +1 bonus to attack and damage rolls made with this magic weapon for the duration of the poison or oil.

Dead Inside

Starting at 10th level, because of the constant exposure to dark oils, dark poisons and the chemical materials in their recipes, your body changes slowly over time. After some time, these chemicals do not affect you as much as they did before. Some say you become stronger and some others say you die slowly.

Additionally, your recipes become more effective and your talent as a dark artist grows.

As a result of all of the above, you can use dark oils and poisons twice instead of once without causing any harm, before finishing a long rest.

Poisoned Blood

Starting at 15th level, your tireless experiments with recipes and the countless failures these experiments brought change your body. This change grants you immunity to poison damage and to being poisoned.

You also discover a new oil recipe that is given below, which is added to your list of known recipes automatically:
