If you’d like to create your own monsters, use the table above for your monster’s stats. You can also mix and match stats from different levels for a different kind of monster. For each special ability added (e.g. the Kobold’s "Noooo!" ability), lower the HP or damage 1 step or treat the monster as 1 step stronger.

Example If you wanted a glass cannon type of enemy, like a mage or an assassin, you can use damage from 1-5 rows higher, and the HP from an equal number of rows lower. A level 5 mage might have 34 HP and deal 26 damage per round. If we give the mage a teleport ability, it’d be as strong as a level 6 monster. For a tanky, defensive creature, lower the damage and increase the HP/Armor.

What die size to use?

Default to d8 for custom monsters—it offers a balanced chance of hitting, missing, and critting. Any die size is fine as long as overall damage per round stays consistent. Here are some thematic guidelines:

  • d4: Undead (slow, with BIG bonus damage).
  • d6: Goblins (small, chaotic, likely to miss or crit).
  • d8: Humans (balanced and reliable attackers).
  • d10: Beasts (stronger than humans).
  • d12: Giants (superhumanly strong/accurate).
  • d20: The mightiest creatures (massive damage).
