Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny wispling. The swarm can’t regain hit points or gain temporary hit points unless it uses its Consume Life feature.

Consume Life. As a bonus action, the swarm-o’-wisps can target one creature in its space that has 0 hit points and is still alive. The target must succeed on a DC 10 Constitution saving throw against this magic or die. If the target dies, the swarm-o’-wisps regains 5 (2d4) hit points.

Ephemeral. The swarm-o’-wisps can’t wear or carry anything and is insubstantial.

Variable Illumination. The swarm-o’-wisps sheds bright light in a 5- to 20-foot radius and dim light for an additional number of feet equal to the chosen radius. The swarm can alter the radius as a bonus action.


Shocks. Melee Spell Attack: +4 to hit, reach 0 ft., one target in the swarm’s space. Hit: 14 (4d6) lightning damage, or 7 (2d6) lightning damage if the swarm has half of its hit points or fewer.
