Void-Touched Cave Spider

Small beast, unaligned

Cave spiders mutated by prolonged exposure to raw Mana leaking from cracked ley line convergence crystals. They are larger than normal cave spiders, with dark carapaces shot through with faintly glowing blue-white veins. Their venom has been altered by the Mana: it disrupts spellcasting and interferes with magical concentration.

Traits

Spider Climb. Can climb difficult surfaces, including upside down on ceilings, without an ability check.

Web Sense. While in contact with a web, the spider knows the exact location of any other creature in contact with the same web.

Mana-Laced Venom. A creature poisoned by the spider's bite has disadvantage on Constitution saves to maintain concentration on spells and must spend 1 additional mana when casting spells (if applicable).

Actions

Bite. *Melee Weapon Attack:* +4 to hit, reach 5 ft, one target. *Hit:* 5 (1d6 + 2) piercing damage plus 3 (1d6) poison damage. The target must succeed on a DC 11 CON save or be poisoned for 1 minute (with Mana-Laced Venom effects). The target can repeat the save at the end of each of its turns.

Web (Recharge 5-6). *Ranged Weapon Attack:* +4 to hit, range 30/60 ft, one creature. *Hit:* The target is restrained by webbing. As an action, the restrained target can make a DC 11 STR check, bursting the webbing on a success.
