TEXT: Belt of Kameha
  Rarity: rare
  Equipment: Belt (requires attunement)
  This simple cloth belt is worn and tattered, and bears 
  wounds of an untold number of battles. While attuned 
  to this belt, When you activate the Energy Beam psionic 
  talent, you may also choose to activate the Beacon 
  psionic talent as a free action. If you do so, the damage 
  dice of your Energy beam increases from a d8 to a d12.
  Ring of Final Destinations
  Rarity: Legendary
  Equipment: Ring (requires attunement)
  This Cursed ebony ring bears a silver inlay of the visage 
  of death itself. When first attuned to a new creature, the 
  ring gains a random number of charges. The number of 
  charges is known only to the DM. 
  While attuned to this ring, if any event (such as an attack, 
  failed save or otherwise) would result in your unnatural 
  death, and the ring has charges remaining, one of these 
  charges is automatically spent, and your death is averted 
  by an absurdly strange or unlikely chain of events. When 
  the ring’s charges are fully expended, It’s silver inlay 
  turns black, and you suffer the following effect:
  • Any time you roll a critical failure, you are 
  immediately reduced to 0 hit points by a convoluted 
  chain of events and happenstance, as determined by 
  the DM.
  This effect lasts until removed by a Wish spell or similar 
  magic, or until a different creature attuned to the ring 
  triggers the same effect.
  Staff of the Class 2 Lever
  Rarity: Very Rare
  Weapon: QuarterStaff (requires attunement)
  This mundane-looking rod of iron makes a surprisingly 
  useful arcane focus, and excels at multiplying force. 
  This Staff contains 4 charges which can be spent in the 
  following ways: 
  • When you cast a spell who’s effects include forced 
  movement, you may choose to expend one charge 
  contained in the staff to double the distance of this 
  movement
  • When you cast a spell or cantrip which deals force 
  damage, you may expend 2 charges to double the 
  amount of this damage.
  The staff regains 1d4 charges at the end of a long rest.
  Belt of Arcane Reserve
  Rarity: Very rare
  Equipment: Belt (requires attunement)
  This intricately crafted belt is made of interlocking 
  plates of silver, and bears 5 enormous gemstones who’s 
  color seems to shift before your eyes. It is highly sought 
  after by mages, who use the gemstones to store unused 
  arcane power for when it might be needed most. A 
  creature attuned to this item may spend a 10 minute 
  ritual to expend a spell slot of 5th level or lower, storing 
  it inside one of these gemstones. As an action on their 
  turn, a creature attuned to this belt may release one of 
  the spell slots stored within the belt, immediately using 
  it to cast a spell they know and have prepared. 
   
  Spell slots stored in the belt remain so until used, even 
  if the creature who expended the slot to store it regains 
  their spell slots through a rest or other means,
  Pilfered Coin of the Rat King
  Rarity: Very Rare
  Item: Coin (requires attunement)
  This well-worn coin has changed hands more times than 
  any can count, and attracts thieves almost as well as 
  it attracts rats. As an action while attuned to this coin, 
  you may throw it at a point within 20 ft. Roll 1d20. On 
  a 1, you realize the coin has been stolen. Otherwise A 
  swarm of Starving and bloodthirsty rats fills a 10-foot-
  radius zone, centered on the coin.
  When the swarm appears, each creature in its area 
  must make a Constitution save. A creature takes 2d10 
  piercing damage on a fail, or half on a success. It must 
  also make this saving throw when it enters the Swarms 
  area for the first time or ends its turn there. Corpses 
  within the swarm’s area are instantly devoured by the 
  rats.
  The Swarm spreads around corners, and lasts for 1 
  minute, or until all creatures within it’s area are dead, 
  whichever comes first. Once this coin has been used, it 
  must be recharged by the light of dusk before it can be 
  used again.
