No sir, you CAN kill the WOF more than one time on a map. All you have to do is wait for the Guide to respawn and you'll be able to throw another Doll and spawn the WOF again.

To answer the question, no. The only way to increase the amount of Cobalt/Mithril/Adamantite on a map is to break more Demon Altars using the Pwnhammer.
