Alnus

As a young boy Hector Tristain awoke from a haunting dream. A large blood red eye with a gold colored iris was before him and spoke in a language he didn't understand. While he didn't know the language he comprehended its desire. Shaken to his soul he spent his life fulfilling its haunting task, creating an object to bring it's site into the material world. His entire life was spent working to create the Alnus, By day trying to perform enough good to undo what the horror the Alnus would bring on the world.

This large ring is made of a strange black material, similar to black onix but much harder on par with adamantine. The empty space is approximately a foot across and the ring itself is 2 inches wide and an inch thick, covered with runes of an unknown language.

While holding the ring it acts as a casting focus. It also gives the attuned the ability to cast counter spell.

Through an hour of meditation a caster can empty a spell slot to charge the Alnus. Spending a 5th ot 6th spell slot gives one charge, 7th ot 8th gives 2 charges, a 9th gives 3 charges. This action can be performed until 30 charges are obtained. After 30 charges can only be obtained by countering spells of 4th level or higher, one charge for countering 4th-7th, 2 charges for 8th or 9th.

The Alnus is fully charged at 50 charges.

While the Alnus has at least 10 charges any spells cast have a +2 bonus to spell save.

Charges can be used to create spells slots. The slot is used immediately cast spells as part of a single action. Slots can be created at any level at a cost of spell level +50% rounded up. These created slots can be of any level and can used to cast any spell up to the 7th level. (example - a 9th level slot can be created to cast a fireball)

Gaze of the Forgotten God: spend all 50 charges on the Alnus- A eye opens inside the Alnus ring and fixes gaze at any point within line of sight of the ring. The wielder chooses either Radiant or Necrotic Damage, at the point the eye gazes upon reality distorts, everything in a 30 radius takes 15D6 necrotic/Radiant damge, 15D6 Psychic damage and 15D force damage. Afterword the wielder must make a Constitution DC of 18 or fall unconscious, even if the DC is passed the wielder takes a level of fatigue.
