Phase Spider

The phase spider can see 60 feet into the Ethereal Plane when it is on the Material Plane.

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

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

The phase spider makes two Bite attacks.

Melee Weapon Attack: +5 to hit, reach 5 ft.. Hit: 8 (1d10 + 3) piercing plus 9 (2d8) poison damage. If this damage reduces the target to 0 Hit Points, the target becomes Stable, and it has the Poisoned condition for 1 hour. While Poisoned, the target also has the Paralyzed condition.

The phase spider teleports from the Material Plane to the Ethereal Plane or vice versa.
