The PS4 version of Diablo 3: Reaper of Souls will get a few new features in addition to its spruced up 1080p visuals (that allegedly run at 60 fps), touchpad support and shorter load times.
As reported by Polygon, perhaps the most exciting new addition to the PS4 version is something called "Avenger Kills," a feature in which certain monsters can kill a player, level up, hop into their friend's game, then try to kill them too.
These monsters will spawn during special events where the skies darken and an announcement will tell the player that "[Insert friend's name here]'s Bane" has arrived. If you manage to defeat your friend's killer, both you and your friend it most recently slayed will get a piece of loot. If the monster kills you, it will level up further and find a friend of yours to hunt. Think of it like a sentient, demonic chain letter. Blizzard is still deciding how to deal with Avenger monsters that get too powerful.
Furthermore, players who acquire a Legendary item from a loot drop will be given a second bonus item that can be gifted to a friend. These gifted items will always be either Rare or Legendary status and can only be used by the player character who opens it - so you can't spread it across multiple profiles.
"Even though you and I are not adventuring together," Berger told Polygon, "I can give you something, and still make it feel like we're playing together."
If you've already purchased the PS3 version of Diablo 3, don't despair: apparently you'll be able to transfer your character from PS3 to PS4, though Blizzard has yet to detail exactly how this will work.
