From living deep underground for so long their secondary eyes learned to help them see in the dark up to 40ft to help when hunting. And when in light and daylight they close their secondary eyes so they aren’t harmed.

Because they are decedent of their queen they are given spider like appendages that grow out of their back which allow them to climb as well as they walk. It also gives them a different unarmed attack with them using their spider legs to jab at the enemy.

At 4th level the Kumo learn how to implement their web into traps and the like. They can lay a 5 ft radius web trap covering a 10ft circle on the ground, wall, or ceiling. It is hidden unless seen by a perception check of 16 or above. When someone walks into it they make a str save of 16 or higher or they are ensnared in the trap. At the start of their next turn they can make another save to get out. When they get out they can walk through the rest of the web as if it is difficult terrain. The Kumo’s ambush has advantage if their target is ensnared in the web when it is used. Laying the web takes 5 minutes.

With the need of it’s spider legs Kumo’s are unable to dawn heavy armor or shields as it would restrict their movement a deadly amount and maybe even harm their spider legs.

At 6th level, Kumo can choose to wrap a grappled opponent in web to prevent them from moving at all. It takes 2 turns and can be stopped with a strength save of 16. If failed then the target is unable to do anything but struggle in the web. They can attempt to escape by making a 18 str save or above. If attacked while wrapped then the web brakes freeing them.

With the need for speed in the underground caverns where the Kumo live they learn to be fast or be dead. Only the fast survive in the colony so they’re a fast species that excel in traversal.

At 5th level, the Kumo learned to anchor their body to a wall or ceiling with web and allow them to attack from afar with ranged weapons. Anchoring themselves takes a moment and costs an action. When anchored they can’t move from their position unless they is a bonus action and cut the web and either fall off or continue climbing. While anchored they can take short or long rests as their body is completely use to the feeling of sleeping like this.

At 2nd level, The Kumo learn how to stealthy sneak through shadows while climbing. With the need for stealth while hunting, Kumo learn to silently sneak across walls and ceilings. They gain adv on stealth checks when climbing Unilluminated surfaces.

With experience gained, starting at 3rd level, the Kumo can ambush from above, damaging the target and grappling them. They have to be10-30ft above the target and they use their dex modifier to land the attack against the targets ac and a str save of 16.
