Lingering Injuries

Here's my expanded and home brewed Lingering Injury rules.  The intention here is to provide injuries that are somewhat less severe than those in the DMG; injuries that a PC might suffer after a fall, botched exploration, etc.  I'll be using these in conjunction with a list of random wilderness travel hazards that I'm compiling.

Healing

Each Lingering Injury has a Severity DC (Severity).  Each Long Rest, a PC with a Lingering Injury rolls a Constitution Saving Throw.  If the result meets or exceeds the Severity, the injury is healed.  After each failed roll, reduce the Severity by 1 to model the effects of healing over time.  The PC should make this Saving Throw after any Medicine Checks or magical healing is performed.

Medicine Checks

During each Long Rest, a character can attempt a WIS(Medicine) Check on someone with a Lingering Injury.  Another character with Medicine proficiency can Help in this attempt.  These healers can attend to only one injured PC per Long Rest.  While there's a good chance that this ministrations will help, there is also a chance that they could make matters worse.

Medicine Check Result
0-5: Increase the Severity by 1d6.
6-9: No effect.
10-14: Decrease the Severity by 1.
15+: Decrease the Severity by 1d6.

Magical Healing

Every 10 points of magical healing applied to the injury reduces the Severity by 1.
