What's Your Story?

Awesome 5e Content Every Month

Welcome back to Calydon, where blood magic continues to stain more than just the streets. A city of white walls, crowded markets, hidden gangs, desperate citizens, and secrets buried beneath every clean cobblestone - where the Vermillion Order continues its work behind a mask of mercy. Disease is studied, blood is weaponized, and the people most in need of help are the easiest to make disappear. Will your players have what it takes to stomach the atrocities?

This 42+ page Urban Blood Magic supplement includes:

  • 5 ready-to-use encounters that can be dropped into an existing game, or strung together into an adventure
  • 5 monster statblocks - Face creatures like the Blood Bot, a blood-fueled construct that bursts through walls and drains victims with a massive needle; the corpse-wearing Hemoscoma; the ravenous Bloodfly; and more!
  • Player Options - 1 new Gravebound subclass and 1 new player subrace
  • 8 new items - Tools, weapons, and gear designed for surviving in the gritty urbanscape
  • 11 new magic spells - Expand our Blood Magic subschool of Necromancy
  • 12 maps and 9 VTT tokens - Bring the bloody horrors to life in your online games!
  • New rules, hazards, lore, and more!

  • I've already said this before and I'll say it again, you guys are fantastic world builders. It's a shame that you guys are underated. It's basically a hidden gem in the world of DnD5e!

    -Breno Pelissoni

  • I loved the unique aspects and themes that you guys create, the crazy creatures like the golem locomotive to the entire theme of the Mages' war. I was very impressed with the high level of quality, thought, and balancing that goes into every bit of work you guys create. It shows the level of dedication, care, and passion the whole team and community has for the brand

  • At first (i was drawn in by) the monster stat blocks, then I bought the sourcebooks and haven’t looked back

    - Archie Wyman

  • I've been playing Dungeons & Dragons for 6 yearsnow, always looking for a new ways to play and things to try. Only (the) CriticalCrafting Team were able to keep up with me for now with their flavorful playeroptions and fun new monsters to defeat. Also who wouldn't want to get to play acowboy or real necromancer, especially that these are not the only great thingsthey offer.

    – Prim

  • I have been following the Critical Crafting crew for a while, and I even picked up the loremaster tier on Patreon. If you're thinking about looking into buying their work, or even supporting their Patreon, you will find it incredibly worth it, for both the quality of content you receiveand the versatility (you) can use it for. No matter if you're a player or a DM, they cater to all players. The community is sincerely one of the best places I have found in small company dnd content creators, with the people being incredibly friendly and with the true light of passion they all have for the game is amazing. It truly is a close community who always welcomes players and dms, new and old with warm and open regards.

  • (The first thing I noticed was) how beautiful the artwork was at first, but what keeps me coming back is how well balanced most of the magic items, monsters, and even subclasses/classes & races
