Pathology

Ill Knowledge

By 2nd level, you have gained additional knowledge regarding diseases and plagues. You gain proficiency in the Medicine skill and the Herbalism Kit, and you have advantage on saving throws against diseases.

Plague Magic

Beginning at 2nd level, you have begun your journey into plague magic. Whenever a creature fails a saving throw against a spell that you cast of 1st level or higher that deals either necrotic or poison damage, the creature becomes infected with a temporary disease. Until the end of its next turn, the creature suffers one of the following effects of your choice:

• The creature's movement speed is halved.
• The creature has disadvantage on Constitution saving throws.
• The creature must spend its bonus action retching and coughing, if it has a mouth.
• The creature cannot gain temporary hit points.

Sanitize & Infect

At 6th level, you have learned how to both remove and bring disease. You add the lesser restoration and stinking cloud to your spellbook, and lesser restoration is considered a wizard spell for you. When you cast stinking cloud, you can choose to have the spell centered on yourself and move with you for the spell’s duration, and you are immune to the spell’s effects while it is active. The spell also does not require concentration when cast in this way. Once you cast stinking cloud in this way, you can’t do so again until you finish a short or long rest, though you can still cast it normally using an available spell slot.

Afflicted Constitution

By 10th level, you have become attuned to the effects of disease. You gain immunity to the poisoned condition and disease.
In addition, you add the contagion spell into your spellbook. When you cast contagion, you can inflict a target with two effects instead of one.
Once you cast contagion in this way, you can’t do so again until you finish a short or long rest, though you can still cast it normally using an available spell slot.

Malady Mastery

At 14th level, the diseases and poisons you create have become dangerously efficient. Whenever a creature fails a saving throw against one of your spells that deals acid or poison damage or inflicts a disease, the creature’s maximum hit points are reduced by an amount equal to twice your wizard level plus your Intelligence modifier for the next year. A creature can only be affected by this ability once per year, and a creature affected by this ability cannot restore these lost hit points for the duration of the effect, aside from the greater restoration or wish spells.
