- Knowledge domain: replace Command with Grant Fluency.
- The creation of teleportation circles is a secret known only to the duergar. The spell is unavailable to non duergar PC’s unless the formula is gained as an adventure reward.
- Translation magic is very limited: the spells Comprehend Languages and Tongues do not exist. In their place is the spell Grant Fluency: 1st level divination (ritual), available to any caster (incl. subclasses which grant casting to non-casting classes), touch range, duration six hours; V and S components. For the duration, you understand the literal meaning of any spoken language that you hear in which the caster is fluent. You also understand any written language that you see in which the caster is literate. It takes about 5 minutes to read one page of text in this manner, or a few seconds for a single word or short phrase. This spell can also be used to create a Circlet of Tongues, a minor magical item which grants basic fluency and/or literacy in one or more languages in which the caster is fluent and/or literate.
