Blood Spider
"A spider from Dream, combined with blood. As usual, this combination results in horrible and dangerous creature. It would be prudent to steer clear of this monster."
The Blood Spider can only be found in the Blood Rooms.
The Blood Spider has 60 HP, and when killed drops 5 gold, and 5 hearts. They are fast moving, and deal 30 damage when lunging, as well as leaving behind webs that your movement speed, and trails of blood goo that inflict 30 damage when stepped on.
Sources and community notes
- The achievements guide says the Blood Rooms are a secret floor reached by a portal from secret rooms.
- The achievements guide lists a Bestiary Keeper achievement, so every enemy page here matters for completing the Bestiary.
