Ioun stone is named after Ioun, a god of knowledge and prophecy revered on some worlds. Many types of
Ioun stone exist, each type a distinct combination of shape and color.
When you use an
Action to toss one of these stones into the air, the stone orbits your head at a distance of 1d3 feet and confers a benefit to you. Thereafter, another creature must use an
Action to grasp or net the stone to separate it from you, either by making a successful
Attack roll against AC 24 or a successful DC 24
Dexterity (Acrobatics) check. You can use an
Action to seize and stow the stone,
Ending its
Effect.
A stone has AC 24, 10
Hit Points, and
resistance to all damage. It is considered to be an object that is being worn while it orbits your head.
Absorption (Very Rare). While this pale lavender ellipsoid orbits your head, you can use your
Reaction to cancel a spell of
4th level or lower cast by a creature you can see and targeting only you.
Once the stone has canceled 20 levels of
Spells, it burns out and turns dull gray, losing its magic. If you are targeted by a spell whose level is higher than the number of spell levels the stone has left, the stone can’t cancel it.
Agility (Very Rare). Your
Dexterity score increases by 2, to a maximum of 20, while this deep red
Sphere orbits your head.
Awareness (Rare). You can’t be
surprised while this dark blue rhomboid orbits your head.
Fortitude (Very Rare). Your
Constitution score increases by 2, to a maximum of 20, while this pink rhomboid orbits your head.
Greater Absorption (Legendary). While this marbled lavender and green ellipsoid orbits your head, you can use your
Reaction to cancel a spell of
8th level or lower cast by a creature you can see and targeting only you.
Once the stone has canceled 50 levels of
Spells, it burns out and turns dull gray, losing its magic. If you are targeted by a spell whose level is higher than the number of spell levels the stone has left, the stone can’t cancel it.
Insight (Very Rare). Your
Wisdom score increases by 2, to a maximum of 20, while this incandescent blue
Sphere orbits your head.
Intellect (Very Rare). Your
Intelligence score increases by 2, to a maximum of 20, while this marbled scarlet and blue
Sphere orbits your head.
Leadership (Very Rare). Your
Charisma score increases by 2, to a maximum of 20, while this marbled pink and green
Sphere orbits your head.
Mastery (Legendary). Your
proficiency bonus increases by 1 while this pale green prism orbits your head.
Protection (Rare). You gain a +1 bonus to AC while this dusty rose prism orbits your head.
Regeneration (Legendary). You regain 15
Hit Points at the end of each hour this pearly white spindle orbits your head, provided that you have at least 1 hit point.
Reserve (Rare). This vibrant purple prism stores
Spells cast into it, holding them until you use them. The stone can store up to
3 levels worth of spells at a time.
When found, it contains 1d4 − 1 levels of stored
Spells chosen by the GM.
Any creature can
Cast a Spell of 1st through
3rd Level into the stone by touching it as the spell is cast. The spell has no
Effect, other than to be stored in the stone. If the stone can’t hold the spell, the spell is expended without
Effect. The level of the slot used to cast the spell determines how much space it uses.
While this stone orbits your head, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell
Attack bonus, and
Spellcasting ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the stone is no longer stored in it, freeing up space.
Strength (Very Rare). Your
Strength score increases by 2, to a maximum of 20, while this pale blue rhomboid orbits your head.
Sustenance (Rare). You don’t need to
eat or drink while this clear spindle orbits your head.
