Hold on to your butts and roll for initiative, because this might be the greatest game we’ve ever played. Together with our sister site, Geek & Sundry, we invited the one and only Vin Diesel to come play Dungeons & Dragons with us… and not only did he accept, he may have become our new best friend.

It’s no secret that our offices are filled with diehard D&D players — Dan Casey, Jessica Chobot, and Malik Forte have each shared why they love the 5th edition, and of course, Geek & Sundry has their beloved D&D series, Critical Role. So when Dan suggested we invite Vin Diesel to our studio for a rousing game of D&Diesel to promote his upcoming supernatural thriller, The Last Witch Hunter, we thought that would be the coolest thing ever. And then he said yes, and it 100% was.

For those in the dark, The Last Witch Hunter stars Vin Diesel as Kaulder, an immortal witch hunter who must team up with a modern day witch (Game of Thrones‘ Rose Leslie) to stop an ancient plague from ravaging New York City. The story was largely inspired by Diesel’s own Dungeons & Dragons character, so what better way to hang out with the action star than by embarking on an epic quest inspired by the film?

Led by our Dungeon Master, Critical Role‘s Matt Mercer, Vin Diesel joined Dan Casey, Jessica Chobot, Laura Bailey, and Travis Willingham for the quest to end all quests. The campaign debuted last Thursday exclusively on Geek & Sundry’s Twitch channel, and now you can watch the best moments from the game in our latest Nerdist Presents.

Make sure you catch the full campaign over on Geek & Sundry, and stay tuned for our in-depth interviews with Vin Diesel, covering everything from The Last Witch Hunter to Marvel to The Fast and the Furious and beyond, coming to Nerdist later this week!

The Last Witch Hunter hits theaters Friday, October 23, 2015.
