Well, with the Curse of Strahd making a comeback to gaming tables, it seems only fitting to expand your player options in the direction of Gothic Horror. Whether you're playing a game set in Barovia or Ravenloft or just your own setting, adding a bit of horror to your game might help spice things up.
Items include the new Revenant Subrace which makes it so "True Res" or "Writing Up A New Character" aren't the only options open to you if your character bites the big one. There's also the Monster Hunter and the Inquisitive archetypes to give you characters who fit in well with Gothich Horror themes.
As usual, this stuff can be thought of as "open beta," and will get some small tweaks and changes before they become official sometime in the future and printed.
