well, if you haven't passed it yet, the dungeon to beat to pass it is the Bowhole
if you mean by the next town, that's Upover
You take it to Wormwood Canyon, the map exit area West of Wormwood Creek.
They can be bought at Wormwood Creek's armour shop. You can also buy the flowing dress in the upover armour shop.
The people in Wormwood Creek won't talk to you if you sail there and enter the village. You can only actually do anything when you end up there as part of the main plot. So continue the main plot, and you'll arrive there in time. Otherwise, there's nothing much to do there.
You go to wormwood creek and go down the well. Then talk to the man who is down in the well. For the quest you have to have the priest on your team defend from an attack thirty times. And you can't flee from the battle.
Ok so u can find it just north of wormwood creek by a big tree u go there and pick it up it's not difficult
WARNING! This Contains Spoilers! I assume you mean wormwood, so, after you defeat the Dreadmaster you go back on the starflight express, aquilla betays you and takes all of the fyggs, you fall out of the starflight express and land in wormwood.
SPOILER you have to defeat Gadorongo, get the Wyrmlight bow and make your way across wormwood canyon before they will actually like you
Head north from Wormwood Creek, follow the coast west to another map area. Walk all the way to the west, then north, you should see a looping pathway on your main map. This is the entrance to the Bowhole.
The red signpost is located on a small island located North of the continent that has Wormwood Creek and Upover on it. I suggest sailing from Alltrades Abbey in between the land masses that have Wormwood Creek and Angel Falls. It's a very small island, and it looks dead. The sign is on the Southern side of the island. Hope this helped.
Angel Falls, Stornway, Zere, Coffinwell, Alltrades, Porth Llaffan, Slurry Quay, Dourbridge, Bloomingdale, Gleeba, Batsureg, Swinedimples, Wormwood Creek, and Upover.
You can find them at NW in a black spot at gleeba near the light bridge at wormwood.
you must give Serena the serene necklace, and then have her unlock the bowhole dungeon for you. get to the bottom of the bowhole, then fight gadorongo and obtain the wrymlight bow. then, go back to wormwood canyon and a scene will unfold. now give the ghost girl her neckalce, have her unlock the dungeon, then fight the monster and get the weapon. then, continue on to the next town
