Lingering Injury - Fire

Burst Knee: Your speed on foot is halved, and you must use a cane or crutch to move. You fall prone after using the Dash action. You have disadvantage on Dexterity checks made to balance. If your knee is splinted with a successful DC 15 Wisdom (Medicine) check, then magical healing of 6th level or higher, such as heal and regenerate, mends the broken leg , or it will heal naturally in 8 weeks. If it is not splinted before it's healed or allowed to heal, the effects remain until it is rebroken and splinted.

Fourth Degree Burns. You have disadvantage on ability checks and Strength, Dexterity, and Constitution saving throws. If you fail a saving throw against an effect that causes fire damage, you also gain the stunned condition until the end of your next turn. Magic such as the regenerate spell cures this damage. If you already have fourth degree burns, you must succeed at a DC 15 Constitution saving throw or die.

Third Degree Burns. You have disadvantage on ability checks and Constitution saving throws. If you fail a saving throw against an effect that causes fire damage, you also gain the stunned condition until the end of your next turn. Magic such as the regenerate spell cures this damage. Alternatively, someone can tend to the burns and make a DC 15 Wisdom (Medicine) check once every week. After ten successes, the burns heal. If you already have third degree burns, you instead suffer fourth degree burns.

Major Neuralgia. You are in constant pain from nerve damage. Whenever you attempt an action in combat, you must make a DC 15 Constitution saving throw. On a failed save, you must take 2d10 psychic damage or lose your action and can't use reactions until the start of your next turn.Magical healing of 6th level or higher, such as heal and regenerate, cures the neuralgia, or if you spend twenty days doing nothing but resting it resolves on its own.

Second Degree Burns. You have disadvantage on Strength, Dexterity, and Constitution checks. Magic such as the regenerate spell cures this damage. Alternately, they will heal on their own in 4 weeks. If you already have second degree burns, you instead suffer third degree burns.

Minor Neuralgia. This has the same effect as Major Neuralgia above, except that the save DC is 10, the damage is only 1d10, and it only takes ten days to resolve on its own.

Horrible Disfigurement. You have burn scars to the extent that can't be easily concealed. You have disadvantage on Charisma (Persuasion) checks and advantage on Charisma (Intimidation) checks. Magical healing of 6th level or higher, such as heal and regenerate, removes the burn scars.

Blisters. You have severe blisters. You have disadvantage on Dexterity checks with your hands, and vulnerability to fire and acid damage. The blisters heal if you receive magical healing. Alternatively, someone can tend to the blisters and make a DC 15 Wisdom (Medicine) check once every 24 hours. After seven successes, the blisters heal.

Heat Stress: You have vulnerability to fire damage. This effect ends if you spend a short or long rest in a cool environment, or if you take any cold damage.
