Drider

The drider can climb difficult surfaces, including along ceilings, without needing to make an ability check.

While in sunlight, the drider has disadvantage on ability checks and attack rolls.

The drider ignores movement restrictions caused by webs, and the drider knows the location of any other creature in contact with the same web.

The drider makes three attacks, using Foreleg or Poison Burst in any combination.

Melee Attack Roll: +7, reach 10 ft. Hit: 11 (2d8+4) Piercing damage.

Ranged Attack Roll: +7, range 120 ft. Hit: 14 (3d6+4) Poison damage.

The drider casts one of the following spells, requiring no material components and using Wisdom as the spellcasting ability (spell save DC 14): Darkness, Faerie Fire, or Web. It can use this action only once per day.
