Downtime
This supplement adds downtime activities for campaigns that include weeks, months, or years between adventures. Characters can use these periods to pursue long-term projects, develop their skills, spend accumulated treasure, and influence the changing world around them. Wars, political shifts, and other events can unfold over an extended campaign timeline. The options can replace or expand on downtime activities in the Player’s Handbook and Dungeon Master’s Guide.
スキルベース（スキルを購入または獲得）ポイント制（ポイントを割り振ってスキルや能力を得る）属性／ステータス制（STR、CON、PERなど）
