Here are the base Damage and Health Ratings for each Survivor Class. This does not factor in any Marksman or Strong Trait that a Hero or Survivor may have. Some of these ratings may be off by 1 or 2 since I can’t quite figure out all of the rounding rules that NG used.
These should be up to date as of 3/15/2018
