This past weekend my legendary smith did the Jamal/Iosep quest to get the bone machete recipe. He completed the Iosep portion and returned to Jamal with the sealed notes from Iosep. When my smith talked to Jamal I got the quest music and accepted the next stage of the quest to get the tainted water from the Grove. At that point I figured I would have the machete recipe. Nope. Instead I noticed in my journal an entry something like, "You try to grasp the recipe for the bone machete but it slips from your fingers." Here's my question: do I need to get the corrupted water samples before I learn the recipe? If so, my only option would be to buy a bone machete from someone to get in to the Grove to complete the quest. Right? Thanks for the help.
