Spiderling (5e Creature)
From D&D Wiki
Medium fiend, chaotic evil
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d6 + 1) piercing damage. If the target is a creature, it must succeed on a DC 10 Constitution saving throw or be poisoned for 1 minute. If the creature fails its saving throw by 5 or more, it is paralyzed while it is poisoned. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
A spiderling is a lesser form of the spider daedra, appearing much like a smaller version of the same.
