Det är faktiskt långt över tecknenes förväntad nivå. En av författarna, Steve Winter har också talat lite om mötesbalansen och designhistoriken.
I ett inlägg ( publicering som Huscarl ) på WotC forum, skrev Steve Winter om mötet "No Room at the Inn":
[in] The original version ... the villains were not assassins but young green slaads polymorphed into human form.
... then young green slaads disappeared from the MM and we were instructed not to use them in this encounter. We cast around for alternatives and found no really good ones, but assassins were at least close to the slaads in power -- as they were then written.
... By the time the monster stat blocks were finalized, assassins wound up significantly more powerful than the original slaads or even than assassins had been when they were chosen as the slaads' replacement.
Betona min.
Han listar sedan eventuella ändringar i mötet som skulle bringa det mer i linje för den förväntade partnivån på den tiden i berättelsen.
