  • Immutable Form. The ioun wyrd is immune to any spell or effect that would alter its form.
  • Ioun Affinity. An ioun wyrd integrates 1 ioun stones into its body. Because an ioun wyrd sees all ioun stones as equal and gains no benefits from them, the wyrd’s ioun stones can be swapped out by any creature the wyrd trusts.
  • Share Iouns. An ioun wyrd can choose to share the benefits of any ioun stones it contains with a single creature within 30 feet. If using optional thirdparty rules for obtaining a familiar, a spellcasting character can bond an ioun wyrd to them as their familiar. In this case, the ioun wyrd always shares the benefits of its ioun stones with its master when they are within 30 feet of the ioun wyrd.


  • Stone Strike. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 7 (1d12 + 1) bludgeoning damage. This is considered a magical weapon.


At first glance, these creatures appear to resemble some manner of earth elementals, but they’re actually bizarre constructs created by spellcasters from certain types of minerals and gemstones. Ioun wyrds are occasionally found in the wild, typically near the haunts of spellcasters and arcane societies where the strange little creatures escaped their former masters. A typical ioun wyrd is roughly 2 feet in diameter and weighs between 15 and 20 pounds.
