Carcer Sanguinis

You slam a lattice of binding runes into the air, anchoring arcane wards to the walls, floor, and ceiling of an enclosed space.

For the duration:

• Undead creatures inside the area cannot leave by any means, including teleportation, mist form, gaseous form, burrowing, or planar travel.

• Undead inside the area have their movement speed reduced to 0.

• Undead have disadvantage on attack rolls against creatures outside the area.

• Creatures outside the area have advantage on saving throws against effects originating from undead inside the area.

Living creatures may move freely.

The barrier is invisible but faintly outlined by drifting crimson runes.

This spell does not damage the creatures contained.

It imprisons.
