    • Water Breathing. The kallidu can breathe only underwater.
    • Sea Commander. The kallidu can issue commands to any creature it can see within 60 feet of CR 1 or lower with an intelligence of 4 or less that has a swimming speed.
    • Minor Telekinesis. The kallidu can move or carry up to 10 pounds of objects in a 30-foot radius with its mind. It can manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. This trait can’t be used to attack, or to activate magic items.


    • Bite. Melee Weapon Attack: +0 to hit, reach 5 ft., one target. Hit: 1 piercing damage.


    Kallidus are found in a wide variety of colors and appearances and vary from two to three feet in length. Naturalists have found that the only physical difference between a kallidu and a typical tropical fish is the abnormally large size of a kallidu’s skull. This large skull houses a powerful mind capable of building magic-powered machines. These intelligent fish are nearly defenseless, but make for powerful foes while operating one of their machines.

    Gather & Build. Kallidus appear to have only two objectives in mind: gather resources and build magical machines. Their need to aggressively gather resources has led them to slaughter of surface dwellers trying to protect their property. Technologically-advanced people have been heavily targeted, and pay a bounty for any kallidus that are captured or killed.

    A Mad Wizard’s Creation. Kallidus were created by a renegade wizard. The wizard was hunted down, but the kallidus continue to grow in numbers and efficiently gather and build. Whether they have minds of their own or are just pawns in their creator’s plan is still unclear.

    Sea Commanders. Kallidus have few physical gifts, but they can accomplish great things by commanding lesser creatures with their psionic abilities. Kallidus typically order their minions to gather materials from shipwrecks, underwater ruins, and even surface communities.
