I am a DM, and one of the things I feel a DM needs to be prepared with is pregen characters incase the worst happens, a character bites the big one and is no more. I tell my players to have back up characters but in the event they do not, or a new player walks in and has not made a character they have the option to pick one of these now. I may never use these but I think they are still essential just in case. Thank you
