I think is stats based because this were my stats to make the event appear.
One point: I never spend points in power when I completed everything my power was in 3 (with the Sigil of Power and some perk IDR) . Then when I increment my power (to learn Elena's skills) I incremented until 20 with runes, accesories and blessings and enter to the church the event appeared.
Thats makes me wonder how to make this event appears right now when I complete everything.
