Duration: Up to 1 minute, Concentration
Class: Cleric, Lich, Wizard
Spell Cost: 9 Points

From either the Ethereal or Material Plane, tear open a rift in the Border Ethereal, from which wailing souls flood into the Material Plane. They flow from a point within range, forming a line toward any direction you choose with a length of 120 feet and a width of 20 feet. Moving out of range of a rift will close it.

The first time a creature enters or starts its turn in the area each round, it must make a Charisma saving throw or receive 12d8 Necrotic damage and fall prone. Those that succeed receive half damage and do not fall prone.

Until this spell ends, you can use an action to tear open another rift or close an existing one. Creatures can only receive damage or healing from this spell once per round, even if they are in a space where multiple zones of this spell overlap.

You can end this spell with a bonus action. When you cast this spell, you can select up to 5 creatures you can see to be protected, spending 1 hit-die per creature. While in any of the zones of this spell, these protected targets restore 12d8 hit-points instead of receiving damage and falling prone. Protected targets may also pass through the rifts, entering or exiting either plane at will. Both damage and healing increases by 1d8 for each hit-die you were missing when you first cast this spell (after spending hit-dice on this spell).
