Our intrepid rogue climbed up the shaft to secure a rope. There was a gasp, and the rope fell. We never saw her again.
An adventurer’s account of a greel attack in Khyber, published in ‘The Korranberg Chronicle’
Well. If that doesn’t set a tone, I don’t know what does.
Lore: The Alien Scavenger
Grells are odd, alien creatures that prefer to ambush stragglers to hunting. They have no eyes and can only move by levitating. They do, however, have a keen sense of hearing and incredibly sensitive skin, allowing them to feel vibrations and electrical fields to avoid being ambushed. While they prefer to hunt alone, they can gather in groups called covens.
They are predators who group their prey into three categories: edibles, inedibles, and Great Eaters (their name for the rare predator that might hunt a grell). They’ll attack those they consider edible without hesitation, though only if they can carry their kill back to their den.
Sometimes, a grell will allow adventurers to pass through its den without issue. They do this in the hope that said adventurers will kill the other inhabitants, allowing the grell to feed on them. Once the larger threats are dealt with, the grell will descend to feed on those that emptied out their home of competition.
The lore here is… meh. It’s fine. It can make for a creepy set piece in a dungeon followed by a briefly terrifying encounter. But there’s not much story telling potential beyond that.
Design: Bird Brain
Ha! I’m funny!

Who came up with this? “Hey, fellow designers on the Wizards of the Coast team, I’ve got an idea! Let’s stick a beak onto a brain! Then some tentacles! We’ll call it a grell!”
I want to shake that person’s hand.
This design is so weird and creative and kind of creepy! You wouldn’t think it would work, given that it’s just a beak stuck onto a brain with some tentacles on it! But for an alien scavenger thing, it works fantastically! It’s kind of creepy in a weird way!
This is definitely one of the best designs we’ve seen in a while. It’s weird and cool and I really like it.
It’s such a shame that it’s downhill from here.
Stats: Disappointingly Straight-Forward
I don’t know why, but I was expecting a bit more from this thing. But oh well.
Grells are hardly durable creatures. Their AC is very low and their HP isn’t much higher. Their only defensive advantages are in their immunties to lightning, blinding, and being knocked prone. Aside from that, they’re hardly difficult to kill.
In terms of actions, they’re incredibly straight-forward. It can hit you with its tentacles, which has a chance to grapple you if you fail a DC, or just peck you with its beak. Both do decent damage for a low-level monster, but not anything that’ll scare the party for very long. By the time the numbers add up, it should already be dead.
This dude could have used from some extra abilities. Maybe put some paralyzing poison on its tentacles or give it some kinda lightning ability? Something, anything more than ‘it hits you’!
For such a creepy monster, it is sure a disappointing fight.
Placement
This is a perfectly fine monster. Not spectacular, but not awful. It has perfectly fine lore, a fantastic design, and really disappointing stats. It’s a very mixed bag, but not an entirely bad one.
With all that in mind, let’s put the Grell on the Best of the Bestiary!

Please tell me I’m not the only one who just noticed the fact that there is a Rug of Smothering—
I need that in my room. Next to the door.

Careful. They’re fickle little buggers.
