From Greyhawk: Monster Summoning VII

[oldkat]

Some suggested 7th Level monsters are:

Stone Golem, Iron Golem, Lich(20th Level Magic-User), Hell hounds, Umber Hulk, 15th Level thief(?), Displacer(?), Beast Pack(??), Hyrdra of 10 (fire-Breathing) Heads

While I wonder about a L15 thief being on the 7th level monster list, and assume the "Displacer" refers to Displacer Beasts... I am at a loss regarding what a "Beast Pack" is...

anyone got any ideas?

It's "Displacer Beast Pack", written on two separate lines.

I can see that. It would have been much too much trouble to put it on one line--even though it would have taken less spaces than the Hydra of 10 (fire-Breathing) Heads
