Running a Business

Downtime Activity: Running a Business DMG p129 Adventurers can end up owning businesses that have nothing to do with delving into dungeons or saving the world. A character might inherit a smithy, or the party might be given a parcel of farmland or a tavern as a reward. If they hold on to the business, they might feel obliged to spend time between adventures maintaining the venture and making sure it runs smoothly.
  A character rolls percentile dice and adds the number of days spent on this downtime activity (maximum 30), then compares the total to the Running a Business table to determine what happens.
  If the character is required to pay a cost as a result of rolling on this table but fails to do so, the business begins to fail. For each unpaid debt incurred in this manner, the character takes a -10 penalty to subsequent rolls made on this table.
