Blackjack

Prerequisites House of Cards, House of Darts, House of Dice, or House of Roulette

When you make a D20 Test and fail, you can roll another d20 and add it to the test, potentially causing it to succeed. If the sum of the d20s exceeds 21, the test automatically fails.

Once you use this trick, you can’t do so again until you roll Initiative or finish a Short or Long Rest.
