Removing body parts
Removing a part from your PC or someone else PC's body is a major set back which will cripple the character both mechanically and RP wise permanently, meaning it requires DM involvement. Any action taken to do so must be carefully considered, to ensure the story is engaging and fun for all involved. Replacing a body part is near impossible, and very difficult to EiG. Meaning the permanent effects is a harsh reality to the victim of the removal.
