Death comes from inside

The Black Plague is a job focused on applying different debilitations to an enemy, and using their applied statuses to boost the power of their other skills, alternatively, they can use sheer brute force to kill them with axe skills.

The Black Plague is a strong job when correctly used, and almost useless when not correctly built or played. It has important restrictions but these come with massive Pay-off.

Best: Many debuff options, high skills scaling, tanky.

Worst: limited potential against some enemy types, very complex rotations and build.

Weapons: Dagger, Sword, Katar, Axe

Gameplay Identity

The Black Plague has a variety of tools that can be used to massively boost the power of its skills, according to one's resources, time and skills, this makes them:

A very resistant debuff-stacker that can apply cumulative damage based on how much they debilitate their enemy with multiple burst window skills.

The Black Plague has many complex rotations. Most of the Axe-side of the tree is very simple to use, albeit with some HP costs and management buffs.

It's strongest potential comes on its poison skills. By applying it through many ways (Envenom, Enchant Poison, Venom Splasher...) one can stack a massive venomous bomb into an enemy, ready to be detonated with different means.

The Black Plague can also carry Toxins, specific items that can be applied anytime to improve their combat capacity and debuff enemies even further. They may also craft such toxins themselves, which might be preferable for long fights as the materials are much lighter than the toxins themselves.

NOTE: The Poison negative status and element have been reworked in Return to Morroc, allowing them to be useful and reliable. Check Stat Changes and Elemental Table for more details.

Core Gameplay Loop

The Black Plague can be a very complex job to manage. Due to the depth of its gameplay style, correctly playing a Black Plague can deal incredible damage and quickly assist any party members due to enemies being very debuffed:

• It's important to apply Poison status to targets to take full advantage of the kit.
• Against poison-resistant enemies, the Axe skills are not only a backup plan but a very viable strategy.
• Toxins are a strong buff/debuff at the same time, when correctly used, can make impossible situations easier to manage.
• There are many ways to passively deal damage as a Black Plague.

• Building a Black Plague is very complex and many skill can be used regardless of situation. It's important to find a healthy balance of offense and utility to ensure the effectiveness of the job.

• Final Skill: Enchant Deadly Poison (Lv3). A powerful buff that increases the multiplying power of most offensive skills of the Black Plague, adding yet another bonus damage layer.

Due to the large amount of tools to keep track of, it's important to elaborate the best way to apply all debuffs to a target, in a way you both have sufficient time to apply all of them, and to make use of them.

A simple example rotation: Apply poison status with Envenom, Increase poison element strenght with Venom Mark, debuff poison defenses with Death Cloud, deal massive damage with Venom Buster, which deals poison-element extra damage according to poison status and state of target. This can be further expanded with Enchant Deadly Poison, Toxins, Axe skills and many more.
