I'm thinking this is a typo, although I like the idea that it's not.
In Ruins of Undermountain, in the Adventures Booklet on pg. 26, it details a monster called guardian skeletons. It says:
"A guardian skeleton has 1 hit die per level of its creator (THACO and saving throws to match) and wields weapons for their normal damage (doing 1-6 points of damage weaponless)."
Ummm...one HIT DIE per level of its creator? In RoU, Halaster is listed as 29th level. That would mean these skeletons are walking around with 29 HD!




I was thinking that they meant 1 HP per level of its creator, which would make more sense given the BTB AD&D rules. But the part about thaco and saving throws to match makes it a hard entry to parse.
There are only a few interpretations for this...
1. These monsters do indeed have the thaco and saving throws of their creator, and 1 HD/level of its creator. In this situation, any guardian skeletons created by Halster would have 29 HD

2. The HD mention was a typo and they meant 1 HIT POINT per level of its creator (which means Halaster would create guardian skeletons with 29hp (not HD), but they would use his thaco of 14 and single digit saving throws (which is clumsy design).
3. The HD mention was a typo and they meant 1 HIT POINT per level of its creator, which means Halaster would create guardian skeletons with 29hp (not HD), but they would use the thaco and saving throws in line with their hp/HD ("thaco and saving throws to match"). For example, Halaster creates a guardian skeleton, it has 29 hp which comes to an average of 6+ HD (by averaging 4.5 hp/HD), a thaco of 15 and double-digit saving throws. This would make the most sense design-wise.
Option #1 seems a bit overpowered and does not seem to be completely in keeping with BTB monster development or tradition. I mean, even a 10th level wizard creating one of these is creating skeletons with 10HD! But on the other hand - damn is that an awesome monster!

Option #2 is clumsy and makes little sense from a BTB rules standpoint. Why 1hp/level of the creator but then use the creator's thaco and saving throws? It makes little sense.
Option #3 makes the most sense from a rules standpoint, technically. But to come to that conclusion means a lot of tinkering with what was written in the description.
So, what does everyone else think?
