Random Effects

Whether you’re using the Chaos Magic house rule or just need a random effect for a potion or herb, this table can help you quickly come up with some ideas.

Roll two D6 dice, or one D20 and flip a coin. Then find the matching numbers on the table (H is heads, T is tails). All effects end after a few rounds of combat, or a few minutes of exploration.
