I was once asked:
Add the DoS of the [applicable sage lore] check to the next check or war made by the caster. This spell requires a physical component (or medium).
I have some questions:
1> Is it possible to "chain" divinations, such that the DoS of a successful divination check is added to a divination check on a subsequent turn, etc., until some great gob of bonus is either expended on some other task, or, more likely, tragically wasted when the diviner rolls the inevitable critical failure (DOOOOHH!!!)?
2> Does divination require the expenditure of at least one mana?
3> The description of divination for Aeromancy omits the requirement for the physical component. Is this an oversight, or do Air Elementalists not require them?
1> No and yes. Making a scry check with divination will give you a modifier to the next check or war, so if the next check was another divination you would add the previous modifier (to make a bigger modifier). Multiple divinations from multiple casters are cumulative.
2> Divination is a "use of power", therefore pool must be expended.
3> Correct, Air elementalists do not need a medium, (as they read the air, water elementalists use water).
Hope that helps!
