Erilipah adds a large variety of debuffs.
Debuff name and details left, debuff icon right
Light Fire - Deals more damage depending on your defense. It also slows you down.
'The more defense you have, the more life you lose and the slower you are'
Infected - Spreads from entity to entity. Turns the debuffed entity black and quickly drains life.
'Find a cure or pray for mercy, but either way, stay away from others.'
Note: This debuff cannot be cured by the Nurse, it can only be removed by dying or The Cure.
If your NPCs get the Infected debuff you can quit out to the main menu and go back in to remove it from them.
