Actions

Multiattack. The spiderdragon summons one swarm of spiders on an adjacent space. It then makes three attacks: one with its stinger and two with its claws.

Claw. Melee Weapon Attack: +12 to hit, reach 10ft., one target. Hit 14 (2d6 + 7) slashing damage.

Stinger. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 17 (3d6 + 7) piercing damage plus 7 (2d6) poison damage. A hit creature must succeed a DC 18 Constitution saving throw or be poisoned for one minute. It can repeat this saving throw at the end of each of its turns, ending the effect on a save.

Spider Breath (Recharge 5-6). The spiderdragon exhales a torrent of spiders in a 30 foot cone. Each creature in that area must make a DC 18 Dexterity saving throw taking 50 (20d4) piercing damage on a failed save, or half as much on a succesful one. 5 (2d4) swarms of spiders will appear on the spaces of and around targeted creatures. The swarms will act immediatly after the spiderdragon in the initiative order and are under the spiderdragons control.

Legendary Actions

The spiderdragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The spiderdragon regains spent legendary actions at the start of its turn.

Detect. The spiderdragon makes a Wisdom (Perception) check.

Stinger. The spiderdragon makes a stinger attack.

Webshot (Costs 2 actions.). The spiderdragon shoots webs in a line thats's 30 foot long and 10 foot wide. Each creature in that line must make a DC 18 Strength or Dexterity saving throw or be restrained. A creature entering a webbed area for the first time on a turn must succeed on a DC 12 Strength or Dexterity saving throw or become restrained by the webs. A restrained creature can use its action to try and escape, doing so with a successful DC 12 Strength (Athletics) or Dexterity (Acrobatics) check. Webbed areas are difficult terrain.

Each 10-foot cube of giant webs has AC 10, 15 hit points, vulnerability to fire, and immunity to bludgeoning, piercing, and psychic damage. Any elemental damage dealt to webbing restraining a creature is dealt that creature as well.
