While the first two Gaiden games, Wizardry Gaiden: Suffering of the Queen and Wizardry Gaiden II: Curse of the Ancient Emperor, stuck fairly close to each-other and to Wizardry V: Heart of the Maelstrom, Scripture of the Dark started introducing more radical changes to the formula. This was mostly in the form of incorporating elements of Wizardry VI: Bane of the Cosmic Forge, but retaining the core gameplay derived from Wizardry V.
Notable additions include:
- Genders (male and female).
- The Faerie, Dracon, Rawulf, Mook and Lizardman races.
- The Alchemist, Bard, Ranger and Valkyrie classes.
- Distinct outdoors areas that do not function like dungeons.
- An Alchemist school of spells (based on both Alchemy and Psionics spells from Wizardry VI).
