Ring of Maniacal Devices (Greater)Equipment 18
Source Pathfinder Core Rulebook
Price 21,000 gp
Weight negligible
This ring seems like simple tarnished brass, but it enhances your curiosity about traps and devices of all kinds.
You can use an Interact action to pull a set of thieves' tools from the ring. These tools appear in your hand and fold back into the ring if they would leave your possession.
They grant you a +3 item bonus to Thievery checks to Disable a Device and to Pick a Lock, and the ring's insights grant you the same bonus to Crafting checks to Craft and Repair snares and traps.
Activate 10 minutes (Interact)
Frequency once per day
Effect You create a 8th-level Glyph of Warding containing your choice of either Prismatic Spray or 7th-level Fireball.
You can have only one glyph of warding from a ring of maniacal devices active at a time, even if you have multiple rings, and the spell ends if you lose your investiture in the ring.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
DivinationThe divination school of magic typically involves obtaining or transferring information, or predicting events.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
