Blight

Blightis a damage over time status effect similar to bleed. Heroes and enemies affected by blight will take health damage equal to the strength of the blight at the start of their turn. Most blights in the game last for 3 turns, or 5 turns if applied with a critical hit. When an enemy is killed by blight, they will not leave a corpse behind (this does not apply if you do not have corpses enabled), giving your party an easier time to get rid of big sized enemies' corpses in order to reach the back ranks if you do not have corpse-clearing skills.

Blight can be removed with Antivenom, the Plague Doctor's Battlefield Medicine, the Grave Robber's Toxin Trickery, the Hellion's Adrenaline Rush, and the Flagellant's Suffer.

During camping, every hero (except Flagellant) can remove blight from other heroes with a shared camping skill Wound Care; the Plague Doctor can cure blight from another hero with her skill Leeches, or from herself with Self-Medicate, and the Flagellant can cure blight on himself with Lash's Kiss. The Shieldbreaker can increase her Blight Resist with her Adder's Embrace. Also, the Antiquarian, Leper, and Abomination are capable of increasing blight resistance with the addition of other resistances with specific camping skills, although the Antiquarian can only give the buff to a companion apart from herself meanwhile the Leper and Abomination grant their buffs to themselves.

Blight, like bleed, can kill a character on Death's Door before they can use an Antivenom on their turn by forcing a Death's Door check the moment the hero takes damage from the blight at the start of their turn. If out of combat, there will be a chance to use Food or Antivenom to prevent death, as long as the party does not move. When using Food to avoid your character dying from blight while at Death's Door, it is recommended if possible to give 1 Food per blight tick if the blight damage is too high to countermeasure with the healing Food provides, and also there's the fact that a hero can only directly consume up to 4 Food from the inventory between battles. If this is not the case and the blight damage is lower than what the Food can heal, then it's better to consume enough Food to not have your hero in Death's Door after each blight tick, resulting in less stress for your party and the same result of keeping your hero alive.

List of Combat Skills That Inflict Blight on Enemies
Abomination's Beast's Bile, Antiquarian's Festering Vapours, and Grave Robber's Poison Darts come with a corresponding debuff to enemies' Blight Resist.

The Crusader's Non-Euclidean Hilt Trinket gives all of his attacks a blight for 2 pts/rd for 2 rds.

Blight Resistance
All heroes have a base resistance to blight, which affects how likely they are to receive blight from enemy attacks. Like most other hero resistances, Blight Resist increases by 10% per Resolve Level. For increasing Blight Resistance beyond Resolve Level and Base resistance, there are various Trinkets and also the Antiquarian's combat skill Fortifying Vapours which grants a small buff to both bleed and blight resistance while also healing a small amount. The Leper also can increase his own blight resistance with his Combat Skill Withstand.

Trivia

 * According to the characters in-game, blight is excruciatingly painful and causes a burning sensation. It is unclear whether blight actually burns the afflicted, but its effectiveness against enemies made primarily of bone or stonework (and thus lacking organs to suffer from poisoning) reinforces the implication that it is corrosive.
