Dungeons & Dragons/Monsters/Bloodsilk spider

In the Dungeons & Dragons fantasy role-playing game, the Bloodsilk spider is a magical beast.

Publication history
The bloodsilk spider appeared in the Monster Manual IV (2006).

Description
They are small, compact, short-legged creatures, far from terrifying and gigantic monstrous spiders, but their silk has an unusual property. Those caught in it gradually have their blood drained by it so the spider can feed by sucking on the webs later. This is very important to the Bloodsilk spider, as without these vampire webs, they have virtually no means of defense or catching food.

They cannot speak, being technically animals.

They are regarded as neutral in alignment.
