AGoM - The Stone of Nerath

This smooth, palm sized stone is cold to the touch. Ripples skitter across its surface, dancing like a flame in the wind. When closely observed, you can see brief glimpses of a foreign landscape, cities and architecture foreign to Parsius, until it's suddenly enveloped in black smoke, fading away. You feel as though you are intruding on the memories of someone powerful as you gaze into that slowly pulsing core. The slow sting of white light, always followed by an abrupt flash of violent dark light. Some nights you hear pecking at your window, servants partaking in a desperate bid to recover something lost and precious. Memories sacrificed in the name of power, now resting soundly within your grasp. It will be returned with you one day, parallel to your death date. How great a reward 𝒮𝐻𝐸 will bestow you upon returning something so precious.

Raven Guardians

The Stone of Nerath reshapes the Spirit Guardians spell when cast by its wielder, with the following modifications:
At the start of each of your turns, choose whether the effect of the spell is Radiant or Necrotic.

Radiant

Bright light emits within the area of the spell, illuminating it in a 15-foot radius. If a humanoid dies within the spell’s area while in radiant mode, their soul strengthens the effect, giving it an additional effect. A Raven Spirit is spawned and persists until the spell ends.

• Acts at the end of the wielder's turn.
• Stat block: Specter, but cannot leave the 15ft spell effect radius and its to-hit modifier is replaced by the spellcaster's spell to-hit.
• When this Raven Spirit is manifested, the wielder regains 5d8 hit points.
• You can manifest a total number of Raven Spirits equal to your proficiency bonus.

Necrotic

• The area within the spell becomes magical darkness (15ft). The wielder can see through this.
• No health absorption or Specter creation occurs in necrotic mode.

Concentration Fail:

• Losing concentration while Raven Guardians is active causes an immediate 3d8 necrotic damage and 3d8 radiant damage.
• This damage cannot be reduced or avoided in any way.
  
  

Worshipers of the Raven Queen are unaffected by the spell’s damage and may freely move through its area without harm.
