Item: Ring of Maniacal Devices (Greater)

This magic 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 Thieves' Toolkit from the ring. This toolkit appears in your hand and any part of it folds 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.

Effect You create the effects of a Rune Trap ritual containing your choice of either a 7th-rank Howling Blizzard or 7th-rank Fireball. You can have only one trapped rune from a ring of maniacal devices active at a time, even if you have multiple rings, and the rune disappears if you lose your investiture in the ring.
