Consume Life. As a bonus action, the will-­o’-­wisp can target one creature it can see within 5 feet of it 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 will-­o’-­wisp regains 10 (3d6) hit points.

Ephemeral. The will-o'-wisp can't wear or carry anything.

Incorporeal Movement. The will-­o’-­wisp can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Variable Illumination. The will-­o’-­wisp 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 will-­o’-­wisp can alter the radius as a bonus action.


Shock. Melee Spell Attack: +4 to hit, reach 5 ft., one creature. Hit: 9 (2d8) lightning damage.

Invisibility. The will-o'-wisp and its light magically become invisible until it attacks or uses its Consume Life, or until its concentraion ends (as if concentrating on a spell).

Unofficial Description: Will-o'-wisps appear as floating balls of light. This light can be of any color.[1]
