Gather the special ingredients for making swamp foot lotion:
Gather 10 tillage mushrooms from around the Tillage Patch Station. They do respawn in same places so you can double back and collect some of the same ones.
Gather 10 pungent herbs. They appear as random harvests around the water reeds on the shores of Firmroot Moot. With standard graphics settings, these may be hard to see until you stand right next to them.
Harvest a bottle of gnomish grease sitting on the counter next to Hambert Cogpocket (Overseer of Operations) at the Dropship Landing Zone ( 1841, 453, 870 ) /waypoint 1841.48, 452.75, 870.30.
Return to Hophip Valorfeet at Firmroot Moot and place the ingredients in the basket next to him ( 156, -89, -473 ) /waypoint 156, -89, -473.
