Dungeons and Dragons – Mystara Secret Crafts
Secret Craft of the Bloodmancer
aka Bloodmancer, Bloodologist or Master of Blood
They are known as a Bloodologist in the library of the Great School of Glantri. They started out (and can still be found) as the Master of Blood or Bloodmancer of the Makai in Ierendi and Minrothad and the Traladaran of Darokin, Glantri and Karameikos. This is an expansion of the Secret Crafts inspired by Gazetteer 3.

This secret craft was developed by those who have a deep connection with necromancy and the element of water. These are abilities granted by the grace of the patrons of the necromancy. Their magic concentrates on dealing with the manipulation of the blood.
Source Material: This secret craft was built from material gained from various editions of the game. Principalities of Glantri (GAZ3), Deep Magic – Blood and Doom (DM12), Encyclopaedia Arcane – Necromancy (Beyond the Grave – MGP1005) and Blood Magic (Oath and Sacrifice – MGP1018), Ultimate Prestige Classes (Blood Child, Darksoul, Blood Hunter).

Secret Craft – Bloodologist – Initiate
- Craft Bonus = Proficiency + Con + circle +2 (Darkness or Water Aspected, Makai or Traladaran)

- Expanded Magic: Characters gain extra spells to their spell list from this secret craft. A prepared caster gains them as spells in their spellbook, a spontaneous caster can swap out the spells with their known spells during craft downtime.
- Artefacts of Blood (Entropy and Water) You can make a craft check to use a artefact of blood without expending the items power by paying for it with your own life force instead. This avoids the chance of a penalty being activated. You can also steal power from an artefact to heal your soul burn. If you are attuned to the artefact, you can use its power to activate your secret craft features without a chance of a penalty being activated. Makai or Traladaran attuned racial magical items allow you to pinch their charges for the day using 1 charge to replace 1 soul burn, and for each level or rarity above common the magical item can replace an additional point.
