Spiders

Characteristics

Disposable. The Spider takes double damage from effects and spells that deal damage based on failed saving throws, and even if it succeeds on the saving throw, it takes normal damage instead of just half damage.

Spider Climb. The Spider can climb difficult surfaces, including upside down on the ceiling, without needing to make 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.

Web Walk. The Spider can climb difficult surfaces, including upside down on the ceiling, without needing to make an ability check.

Attacks

Bite. Melee Natural Weapon Attack, +3 to hit, 5 ft. reach, one target. On a hit, deals 2 Piercing damage.

Web (Recharge 6). Ranged Natural Weapon Attack, +3 to hit, 15/30 ft. reach, one target. Upon hitting the target, it becomes Restrained by webs. The target can use an action to make a DC 13 Strength check, escaping the web and ending the condition on a success. The web can also be attacked and destroyed (AC 10; 5 hit points; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).

Characteristics

Collective. The Spider Colony can enter and exit the space of a creature that is the same size or smaller than itself. The space within the Collective is considered difficult terrain, and the Collective has advantage on attack rolls against creatures within it.

Division. The Spider Colony can split into two Spider Colonies one size category smaller using a bonus action, losing half of its maximum and current hit points in the process, and Bite's damage dice are reduced by one category. A Spider Colony can merge with another of the same size using a bonus action, adding their maximum hit points and increasing their damage dice by one category. A Spider Colony cannot be smaller than Tiny. A Tiny-sized Colony splits into 1d4 Spiders.
