Mission from Sigil
Ioun Stone, Iridescent Spindle
Effect: Sustains creature without air
- These crystalline stones always float in the air and must be within 3 feet of their owner to be of any use. When a character first acquires a stone, she must hold it and then release it, whereupon it takes up a circling orbit 1d3 feet from her head. Thereafter, a stone must be grasped or netted to separate it from its owner. The owner may voluntarily seize and stow a stone (to keep it safe while she is sleeping, for example), but she loses the benefits of the stone during that time. Ioun stones have AC 24, 10 hit points, and hardness 5.
We found three ioun stones after the battle with the Taskmasters in the Formian Hive. Akira took the iridescent spindle because it will be useful for the work she does with poison.
