This article is about the plant grown by trolls. For the plant you can grow yourself, see Goutweed (plant)
Hardy Goutweed is a grey herb that is grown by My Arm during the My Arm's Big Adventure quest, helped by an adventurer.
After the Making Friends with My Arm quest, a similar patch is found in Weiss where Boulder grows his hardy goutweed.
For this farming patch, all actions should be done by My Arm instead of the adventurer, so the farming items should be used on My Arm instead of the patch. The herb is grown on a new farming patch instead of the herb patch next to it.
Farming experience is only gained when My Arm picks the hardy goutweed, not during the other farming steps.
