Lot's of cool new stuff to talk about!
Sanity
This version of the game introduces a sanity mechanic called "wits." This is an experimental system that will require players to manage their character's sanity level. Delve too deeply, too fast, and you may wind up in serious trouble.
There are ways to mitigate your sanity. Having a nice cup of tea can help a lot!
Allies
Allies will require a little extra effort on your part. A saucer of milk, a bone, a shiny gem ... and some darker things may be necessary to convince the denizens of the underworld to join you in your quest
Demotivated
Enemies can get demotivated now. If you stop attacking them, they can be talked to, traded with and more ... albeit reluctantly.
