Issues Without Official Errata
- Do agent bond scores increase as Arts (Houses of Hermes: Societates, p. 144) or as Abilities (Lords of Men, p. 25)? [1]
- RoP:M, p. 39: Oath-Swearing costs 10 points like a level 50 effect, but Init is Qik-10 as for level 25. The Ritual Power Magic Quality only gives 25 levels of powers. Proposed Solution: In analogy to the Binding Oath Ritual Faerie Power from RoP:F, p. 56 (which is 50 levels) change Init to (Qik-20), cost to Ritual Power x 2. [2]
- Inconsistencies concerning the waxing and waning of Infernal power[3]:
- RoP:I p. 11: "At dusk on Good Friday, all Infernal auras are temporarily reduced to a strength of zero, and the Dominion often flows to fill the spiritual void. This situation lasts until Easter Monday, at which point, over the course of the following week, Infernal auras gradually regain strength at a constant rate, until they are back to their resting values."
- This is contradicted by DE p. 415: "Infernal auras are particularly strong on Easter Saturday, the day between the Crucifixion and the Resurrection."
- However, DE p. 478 suggests that Easter Saturday is a bad time for demons: "In Christian lands, all demons are forced to abandon their physical form at dawn on Holy Saturday (the day between Good Friday and Easter Day); furthermore, no demon may spend Might points from this point until dusk on Easter Day. This is a reminder of Christ's victory over Satan and subsequent descent into Hell to bring the good news to the souls trapped there."
