Ethereal Jaunt. As a bonus action, the spider can magically shift from the Material Plane to the Ethereal Plane, or vice versa.
Spider Climb. The spider can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Web Walker. The spider ignores movement restrictions caused by webbing.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 7 (1d10 + 2) piercing damage, and the target must make a DC 11 Constitution saving throw, taking 18 (4d8) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
Description
A phase spider possesses the magical ability to phase in and out of the Ethereal Plane. It seems to appear out of nowhere and quickly vanishes after attacking. Its movement on the Ethereal Plane before coming back to the Material Plane makes it seem like it can teleport.
It's always fun to use the Ethereal Plane to walk right through a party's carefully crafted camp walls!
Just got this as a mount his name is Tedi
I mêan I was about to judge and then realised that I tamed a bulette, so I mean...
Now how did you actually do that?
You don't want to know...
no actually just a bunch of food, charm spells, me playing my lute like a madman, feeding the BBG to him
Our cleric has successfully tied up one and plans on making it a pet. His name will be Darth Plagueis
WISH HIM LUUUCK!!!
I also teared one's legs off and plans on making a poison dispenser.
Does the spider draw an opportunity attack when it leaves the material plane?
No, doesn't leave reach.
"You can make an opportunity attack when a hostile creature that you can see moves out of your reach. To make the opportunity attack, you use your reaction to make one melee attack against the provoking creature. The attack occurs right before the creature leaves your reach."
Second part:
You can avoid provoking an opportunity attack by taking the Disengage action. You also don't provoke an opportunity attack when you teleport or when someone or something moves you without using your movement, action, or reaction. For example, you don't provoke an opportunity attack if an explosion hurls you out of a foe's reach or if gravity causes you to fall past an enemy.
So as a DM how do I use Ethereal Jaunt? Can it attack out of it? Can PC's attack it/ see it?
The PCs can't see it unless they can see into the Ethereal Plane, so it also can't be attacked by them. It must shift back into the Material Plane before it can attack.
Faq: does jaunt provoke an attack of opportunity? No it's the same as misty step in that way.
Which Chris Perkens made an official ruling on in a Twitter thread.
A great example of a evil and clever DM.

Can creatures or objects be pulled through the plane...like if the spider grabbed someone...then moved to the another plane?
I guess it should be able to. But it wouldn't want to (unless instructed by the big bad for example, to imprison PCs) as the spider phases to escape being attacked that turn.
Thank you!
Well if it could do that then the creature would definitely need to be paralyzed of willing, and you would then need to note that a party member is likely to be easily picked off to the ethereal plane and killed so the Cr should be higher, but it technically shouldn't be able to do this at all but it's up do DM interpretation.
And it would DEFINITELY WANT TO DO THAT.
A player of mine has a vintage wine made of Phase Spider blood
Only the spider can shift into the ethereal plane, not its prey. So the spider can't return there with any prey.
