A reward in my Oriental Adventures campaign. Posted here for my PCs to reference. I am using the nemuranai tag for OA magic items since in Japanese Mythology magic items are not forged or made (this is seen as disrespectful to the indwelling spirit). Instead, the items awaken through various processes – spontaneously, or through powerful magic.
Wondrous Item (amulet), legendary (nemuranai, requires attunement by a wu-jen)
Omen: After wearing the amulet for at least 1 hour, it grows warm and the nine-tales occasionally moves and purrs (audible only to the wearer).
This platinum amulet has a jade set-piece and depicts a nine-tail kitsune – a powerful icon of magic.
The amulet has 50 charges for the following properties. It regains 4d6 + 2 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 20, the staff regains 1d12 + 1 charges. As a nemuranai weapon it grants its benefits based on the attuned characters proficiency bonus:
- Void Adept. While you wear the amulet, you gain a +1 bonus to spell attack rolls. You may expend 2 charges to increase this bonus to +2 or 4 charges to increase this bonus to +3 for the duration of an encounter.
- Arcane Health. You gain 10 temporary hit points each day at sunrise. These hit points remain until expended or 24 hours pass.
- The Fire of Inspiration. You can use an action to cast one of the following spells from the staff without using any charges: arcane lock, detect magic, enlarge/reduce, light, mage hand, or protection from evil.
- Element of All Thing I. You can spend a charge to cast arcane spells of up to 3rd level that are extended as though using the Extend Spell metamagic class ability.
The Five Rings. You can use an action to smash the amulet. The amulet is destroyed and releases its remaining magic in an explosion that expands to fill a 30-foot-radius sphere centred on it. You have a 50 percent chance to instantly travel to a random plane of existence, avoiding the explosion. If you fail to avoid the effect, you take void damage (unspecified damage) equal to 16 × the number of charges in the amulet. Every other creature in the area must make a DC 17 Dexterity saving throw. On a failed save, a creature takes an amount of damage based on how far away it is from the point of origin, as shown in the following table. On a successful save, a creature takes half as much damage.
Nemuranai were man-made items of exceptional quality that had had their kami awakened, either through the skill used in creating them or through their association with great deeds. These items can usually only be attuned or used by a single person. They grow in power as the hero who owns it also grows in fame, honour and power.
