Talk to Jonette (near Conflux #3), she will ask you to find her cookbook which she dropped.
You must find and click on a specific ??? to receive the Key Item Torn recipe page.
There are 4 places where the ??? can spawn, which cycle every ten minutes in the following order:
1. Spiders (Closest Conflux #00)
2. Colibri (H-8/9 - SW of Spiders)
3. Peiste (J-11) (Closest Conflux #07)
4. Bugard (K-11) (Closest Conflux #08)
Care must be given at Spider camp not to aggro the NM spider Athamas T(H). Colibri camp is completely safe. Peiste aggro sight but be wary; a Peiste NM named Gukumatz can spawn within the Peiste here and aggros T(S). Bugards aggro to sound.
Once the pattern is discovered, a fast run can be done in 2-3 minutes, average 4-5 minutes, and long runs are 6-7 minutes.
Return to Jonette for your reward and possibly one of:
