In the Dragon Age RPG, we are told on page 47:
When doubles are rolled on certain types of tests, this generates stunt points. You can then use these points to pull off a number of special maneuvers. Stunt points are used primarily in combat encounters (see page 54) to keep fghts dynamic and fun, along with spell stunts, which let mages enhance their spells (see page 106).
Here's the problem... per page 46, tests require you to roll three dice. So, rules as written, it is impossible to roll doubles, as you are never rolling two dice. There seems to be no place in the rules where you only roll two dice for a test. There's also no rules example in this section.
However, many of the game's equivalents to "critical hits" require stunt points, generated by "rolling doubles." So, what are doubles?
Trying to read the rules lead to four interpretations.
- Any Two Out Of Three: "Doubles" count any two dice among three matching, including the dragon die as a die that can match. While it's the most permissive interpretation of the rules, it's unlikely from a gameplay standpoint; matching two on 3d6 leads to 4/9 of rolls (technically 96/216) generating stunt points. (This also leads to a followup question: if all three dice match, do these "triples" count as "doubles"?)
- Doubles Only Count Non-Dragon Dice: "Doubles" count the two non-dragon dice. This is the most sensible from a grammatical standpoint, since the two non-dragon dice are the only pair of dice you roll in a test. However, it would still generate stunt points 1/6th of the time.
- Tests Are 2d6, The Dragon Dice Is Rolled With The Test In Case It's Needed: Tests are just 2d6 + modifiers, with the 'dragon die' rolled simultaneously with the test die but the dragon die's value only becoming relevant if the 2d6 come up doubles. This is another possible reading of the rules, since the rules never explicitly state that the dragon die is added to the result of the test; the only mention of using the value of the dragon die outside of generating stunt points are the opposed test tiebreaker rules and the degree of success rules on page 48. This still generates stunt points 1/6th of the time.
- Tests Are 2d6, 'Doubles' Are Generated If The Non-Dragon Dice Match The Dragon Dice: Implied by the paragraph of Combat Stunts on page 54, it has the most sensible frequency for generating stunt points (1 in 36 rolls). However, it is contradicted by the rules example on the following page.
