All of this will be coming to the game when it launches on PC next month but, sadly, not sooner. First up is crafting your own skill books (some of which are not available as random drops or buys in the game) by combining other skill books (e.g., Necromancy + Water = Blood Rain), then rune crafting to boost your gear, and finally talking to ghosts. If you're interested in what else Larian has in store for the game, then the rest of the video goes on to talk about a few new features coming to the sequel.
If that's all you care about, then watch those two minutes, be joyous and happy, and enjoy the rest of the day! The co-op features are covered (rather cleanly, I must say) in the first couple minutes of the update video. But wait, it gets better! Combo co-op, either online or via LAN, will also be supported.
The most recent Kickstarter update video for Larian Studios' Divinity: Original Sin 2 shows off a feature that we've been anticipating: local co-op on the PC.
