Roleplaying an injury on a roleplay server is not only beneficial to the roleplay of bystanders that interact with your character, including the fire department, but it is also crucial to the development of your character and an injury can play an immensely important part in the future actions that your character will take. For example, if your character was shot due to trespassing on a gang's turf, they would know not to return to the area out of pure fear of repeating their injuries and going through the exact same pain and trauma that they previously did.
There are multiple types of injuries, so many that it would be difficult to list all of the injuries that you could possibly roleplay. Psychological or mental injuries are usually an entire different field of expertise, however I'll briefly go over a few that are common simply to benefit this guide. By utilising the information within this guide, you'll be able to strengthen your roleplay and provide more detailed roleplay for your injuries for not only the fire department but everybody around you, including your character. If you want more information on how to roleplay a certain injury, reply to this thread and I'll happily explain how to roleplay it by adding a new section, or adding additional information to a certain section.
