This cloud of buzzing insects boils toward its victims, droning ominously in its strangely deep pitch and accompanied by the sickly sweet aroma of blood.

A bloodmote cloud is made up of undead mosquitoes with a blood thirst. While a living mosquito is hardly more than an annoyance, and a swarm of the same is hardly cause for alarm, the appearance of a concentrated swarm of undead bloodsuckers is a calamity.

Combat

A bloodmote cloud seeks to engulf and suck dry any living prey it encounters. A bloodmote cloud is never sated.

Blood Drain (Ex): A bloodmote cloud drains blood and deals 1d3 points of damage and 1d2 points of Constitution damage to any creature whose space it occupies at the end of its move.

Diet Dependent: A bloodmote cloud is diet dependent (see Undead Metabolism) upon blood, which it consumes by using its blood drain ability.

Distraction (Ex): Any living creature that begins its turn with a bloodmote cloud in its space must succeed on a DC 15 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.

Turning: See Undead Swarms and Turning.
