I ran it once as a oneshot with 6 players, warned my players that it is deadly, had everybody roll up three chars but slightly underleveld in return.
Was fun because it palyed like lemmings.
Spoilers ahead
Highlights include:
Having two hirelings in a row crushed by the stone wall/door in front of fake entrance number 1
A melee cleric losing his arm to the sphere of annihilation, becoming fatalistic because he is now useless in melee and using his remaining arm to touch everything else in the dungeon. Except he was so unlucky at being suicidal he missed the all the other dangerous things, which then proceeded to kill functional party members.
Losing one rogue-type character and having a second one massively hurt trying to defusing a magic missile trap on the ceiling, which ultimately leads to a room the characters already visited
A halfling fighter being teleported into a metallic 10x10x10ft cube with levers at one side.
He pulls them randomly, drops into another pit with vermin at the bottom. Both roll so horrible that they spend almost 5 minutes trying to kill each other until the halfling finally succumbs. During that time the rest of the party was desperately mounting a rescue operation, which found the metal cube 2 rounds after his death. another character climbs in, pulls the levers, drops onto the dead halfling, dies from the fall since he already took damage earlier.
A paladin like character getting dominated by a brain in a jar, attacking other characters. The rest of the party believed he he is acting on paladinly instinct, assists him at first.
2 small party members with heavy armor drowning in the room that floods with blood.
The party running out after killing the caster in the crypta, already in the process of packing up as they realise their mistake, stone-to-sanding their way back in, expending their highest level spells before continuing.
Touching the skull.
