Quick point of clarification: when you apply a tag/role, you add +1 to your role. You don't get more dice. From the rulebook:
For example, the First Knight attacks an opponent with their chosen weapon. They use the role Super Soldier, and all 3 tags under it are applicable, so they roll 3D6 and add 4 to the total.
Thanks The Dev Team for pointing it out. I decided to go for a lower number of tags (compared to Lady Blackbird), and it was easier to work out the probabilities with the sum of 3D6. Without role/tags, a character has just over one third chance to succeed. With a role and 1 tag, the odds is increased to just under two thirds.
