Path of the Plague

.

Plague Carrier

At 3rd level when you adopt this path you gain resistance to poison damage and advantage against being poisoned and the ability to cast detect poison and disease, but only as rituals, as described in the Spellcasting section.

Plague Aura

Starting at 3rd level, you emanate a sickly, magical aura while you rage. The aura extends 15 feet from you in every direction, but not through total cover.

When you enter rage each creature of your choice within your aura must make a Constitution saving throw against your Plague Aura DC, on a failed save they take 1d6 + half your barbarian level in poison damage, on a success they take half damage, and you can activate the effect again on each of your turns as a bonus action.

your Plague Aura DC equals 8 + your proficiency bonus + your Constitution modifier

Plague Soul

Starting at 6th level, you Plague Aura begins to slow your enemies within. Whilst raging your aura counts as difficult terrain for hostile creatures. In addition whenever a creature takes damage from your Plague Aura you ignore resistance to poison damage.

System Shock

At 10th level, your control of toxins is great enough to disable a foes nervous system. As an action choose a creature within 60 feet you can force it to make a Constitution saving throw against your Plague Aura DC, on a failed saving throw it takes 6d8 poison damage and is paralyzed until the start of your next turn. On a successful save they take half damage.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Infectious Aura

Starting at 14th level, when you enter rage you can activate your Infectious Aura gaining additional benefits to your Plague Aura.

For one minute your Plague Aura gains the following benefits:

• Your Plague Aura now becomes 30ft.
• Whenever a creature fails your Plague Aura DC they also become poisoned for one minute and can repeat the save at the end of their turn.
• Whenever you deal poison damage you ignore creatures Immunity to Poison damage.
• If a creature dies within your Plague Aura you can use your reaction to animate it. It remains animate until the end of their next turn, after which time it collapses and dies. While animate in combat it has 1 hit point and It obeys your mental commands, and the only action it can take is the Attack action, making one melee attack.

Once you use this feature, you can’t use it again until you finish a long rest.
