We played through this fairly late in our 80s campaign (probably around 1989 -- right before we switched over to 2E). I remember we played through the entire thing in 1 long session, and the players did pretty well (retrieving all 3 items). The thing that actually stands out most in my memory, though, wasn't actually part of the module, but something that happened in the aftermath.
One of the PCs, Grimrick the thief -- the longest-standing character in the campaign, who had narrowly avoided death many many times when most of the other PCs didn't (meaning he got to keep all the treasure and XP for himself) -- had been killed in the final combat with the ogre mage -- shattered into bits and pieces by a
cone of cold, IIRC. The survivors dutifully swept the fragments up into a large sack which the party's mage slung over his shoulder and
teleported back home to get him
raised. Unfortunately, the targeting roll came up 00 -- low arrival, materialized in solid matter, permanently and irrevocably killed. Grimrick's player was
freaking out at the prospect of permanent character-death, all the other players (and, I'll admit, me too) were feeling significant
schadenfreude at seeing this infamous rogue of a character finally fall prey to the sort of fate he'd so often benefitted from. Even the guy playing the mage didn't mind losing his character as long as he was taking Grimrick down too (after all, this mage was a replacement character, generated at about 6th level after this player's other characters had died). "But," insists Grimrick's player,"we don't know
how far he came in low." Sure enough, the spell description in the PH doesn't say -- it talks about distance for coming in high, but not low. After several minutes of negotiation, we decide to roll (1d20, I think) to determine how low he came in. The mage's player rolls, and sure enough he comes up with a 3 -- he materialized 3 feet below his target -- meaning that he was still instantly and irrevocably killed (cut in half),
but the bag holding Grimrick's remains, which was slung over his shoulder, was sitting unharmed on the floor of the mage's study. The mood in the room changed in an instant, from sorrow to joy and vice-versa, as everybody realized that, somehow, Grimrick had managed to pull through yet again, and the mage's player realized he'd be rolling up yet another replacement character without even having anything to show for it
