Let's assume that going to the local humanoid settlement and magically blasting to death a townie isn't an option. Likewise, any cunning plan to lure—magically or otherwise—a humanoid from that settlement to you won't work either. The spell or combination of spells must bring forth a humanoid corpse that lasts for at least 7 days, 10 preferred.
Scenario: Deadly Dancers on the Ethereal Plane
To make another deadly dancer (Tome of Magic 80-1) a deadly dancer needs a humanoid corpse.
In my campaign a troupe of deadly dancers resides on the Ethereal Plane near a fortress filled with humanoids. The deadly dancers were ambushing patrols in hopes of snatching humanoid corpses so that the troupe can make more of its kind. This was dangerous: patrol leaders are hardened war veterans, and the troupe's losses barely equaled the recovered humanoid corpses. A red ethergaunt—that can cast spells like a 9th-level wizard—discovered this troupe of deadly dancers, learned their dance-based language (I'm so not kidding—take that, Drow Sign Language!), and earned the troupe's allegiance by using the 5th-level Sor/Wiz spell lesser planar binding [conj] (PH 261-2) to call low-level fire gnomes (Planar Handbook 125-6). Rather than cutting deals with the fire dudes, the red ethergaunt has the deadly dancers murder the extraplanar fire dudes, and the dancers employ the corpses to increase the troupe's number.
While the ethergaunt's process works, the optimizer in me sees this process as clumsy and thinks that a red ethergaunt with its Intelligence score of 23 (and the folks on RPG SE) can do better. With access only to…
- 5th-level and lower wizard spells (so, for example, humanoid corpses can't be created from statues via the 6th-level Sor/Wiz spell stone to flesh [trans] (PH 232)) and
- no more than 4 different spells per level yet only 2 different 5th-level spells and
- basic magic items suitable for a scout (e.g. everlasting rations (Magic Item Compendium 160) (350 gp; 1 lb.), a healing belt (MIC 110) (750 gp; 1 lb.))
…are there other, more efficient ways to generate humanoid corpses to facilitate deadly dancer reproduction that don't involve interacting with a settlement?
