This page details how I use the 5th edition rules. Comments welcome.

Only rules from the core rulebooks and Xanathar's Guide are allowed.

• All races from the Player's Handbook are allowed with the following restrictions:
  • Dragonborn and Tieflings are not allowed.¹⁾
• All Variant Rules in the Player's Handbook are allowed – with the following comments:
  • Equipment Sizes (PHB, p.144): Using armor of a different size is allowed without modification. However, a day of this will incur one level of Exhaustion (PHB, p.291).
  • (others?)
• Significant Injury Houserule: When a character drops to zero hit points, they acquire one level of Exhaustion (PHB, p.291). Every time they fail a death saving throw, they acquire one more level of Exhaustion.
• Combat is typically done on a square-grid battlemat with miniatures.
