Universe:
Focus - If a task is aligned with a focus that you have then each success counts as 2 successes for overcoming difficulty or generating momentum.
Not quite how a focus works. It only increases the chance of getting 2 successes from one die.
You need to roll TN or less to get a success. A "1" is a critical and gives you two successes.
If you have a Focus that applies, you get a critical on a roll of your Discipline or less.
Example:
Cheng attacks a Romulan with his ushaan-tor. Daring 10 + Security 4 gives him a target number of 14. I decide to add Threat to buy 2 bonus d20s. This gives Universe 3 extra Threat, but I get to roll 4d20.
Say I roll 3, 5, 14, and 19. Normally, that would be 3 successes for 3 dice below 14 and no "1"s.
But, Cheng has the Focus Hand-to-Hand Combat. With his Security Discipline of 4, that turns the die that rolled a "3" into a critical giving him an additional success.
