These crystalline stones always float in the air within three feet of their owner while active. When a person first acquires a stone, they must hold it and then release it with a single action command, whereupon it takes up a circling orbit 1d3 feet from their head. Thereafter, a stone must be grasped or netted to separate it from its owner with a DC 40 check. The owner may voluntarily seize and stow a stone without a check, but they lose the benefits of the stone during that time.
Ioun stones have AC 30, Hardness 10, and Toughness 6. The powers of each stone vary depending on its color and shape. You can have up to three stones active at a time. Each floats a different distance from the user’s head. The tag for an ioun stone depends on its effect or spell at the GM’s discretion.
If an intact ioun stone ever gains the Broken condition, it is treated as cracked. If a cracked or flawed ioun stone gains the Broken condition it becomes a Dull Grey stone. A cracked or flawed ioun stone cannot be repaired. Unless otherwise listed, an ioun stone is a common item.

Some ioun stones have extra rules:
- Agate, Cracked Pale Orange, and other ioun stones with a one-time use become a Dull Grey ioun stone after being used.
- Lavender, Pale Lavender, and those stones that absorb spells require their users to expend a reaction to absorb a spell. Absorbed spells can then be used to power the user’s own spells. The user can expend a number of absorbed spell levels equal to or greater than the level of their spell being cast. This reduces the number of usable spell levels that were absorbed. However, it does not reduce the number of levels the stone absorbed for the purpose of reaching it maximum number of spell levels it can absorb. Once the maximum number of spell levels a stone can absorb is reached, that stone becomes Dull Gray ioun stone.
- Orange stones users can change the Spell Slot and Spell Known each time they gain access to a new Spell Level.
- Pearly White stones only cure damage with Regeneration that the user took while the stone was active, not prior to its activation.
- Vibrant Purple stones store spells cast only by a creature with the Spellcasting trait, but the stored spells can then be used by anyone at any time in the future. Those who cast the stored spell, can regain their expended Spell Slots after resting without the ioun stone losing the stored spell.
- Those with Item bonuses stack with each other, unless otherwise stated. All active ioun stones count as a single Item bonus for the purpose of determining the limit of Item bonuses.
Crafting Requirements: You must be able to craft runes. When crafting an ioun stone, if you fail the check, rather than failing completely to make it, it is cracked or flawed. Roll 1d100. On a 01-60, the stone is flawed and on a 61-100 the stone is cracked. A cracked stone is worth half as much as an intact stone and a flawed stone is worth a quarter as much. This sometimes drops the rarity of the stone too.
