Expanded Injuries

Here are some variant rules you can add to the Injuries module presented in chapter 9, “Dungeon Master’s Workshop,” of the Dungeon Master's Guide.

Confirm a Lingering Injury

When you suffer an effect that would cause you to roll for a lingering injury, first roll a d20. On a roll of 1–9, roll on the Lingering Injuries table as normal. On a roll of 10–20, the effect doesn't cause you to suffer a lingering injury. This variant rule is meant to reduce the number of lingering injuries which occur at the table.

Lose an Eye, I Choose You

When you score a critical hit by attacking a paralyzed or unconscious creature within 5 feet of you, you can choose the lingering injury which effects the creature as a result of the critical hit instead of rolling on the Lingering Injuries table.

You Fireballed My Leg Off!

In addition to the options already presented in the Dungeon Master's Guide, a creature may sustain a lingering injury after rolling a natural 1 on a saving throw against a spell, magical, or trap effect that deals damage to the creature.
The Expanded Lingering Injuries table is meant to expand the injury options from the ones presented in the Dungeon Master's Guide. Whenever you would roll on the Lingering Injuries table, you can choose to roll on the Expanded Lingering Injuries table instead.
