Harpooner's Wading Kilt is one of several new Mythic one-piece item sets that came out with Update 30 otherwise known as the Blackwood Chapter.
At the time of release, it is considered a best-in-slot (BIS) item to have for a PvE Damage Dealer regardless of whether they're Stamina DPS or Magicka DPS in similar fashion to the release of previous Mythic items such as the Ring of the Pale Order or Thrassian Stranglers.
Like all other Mythic items, Harpooner's Wading Kilt can be found by finding a total of five different and unique Leads. Upon finding Leads, one must Scry for the Leads' locations and then Excavate them through the Antiquities Skill Lines under the World Skills ingame.
This Lead can be found in either Normal or Veteran Ruins of Mazzatun, a DLC dungeon located in Shadowfen part of the Shadows of the Hist DLC.
To save time, simply do Normal Ruins of Mazzatun. This Lead only drops on the last boss and nowhere else in the instance. Veteran does not have a higher chance of dropping the Lead. The Lead is not shareable between group members.
This Lead can be found in the Blackwood Chapter zone by killing any of the World Bosses. We recommend going back and forth between the two World Bosses located in the southeastern part of Blackwood for the sake of time and efficiency. You can solo or group up for these World Bosses.
This Lead drops from enemy mobs, most predominantly from Daggerfall Covenant soldier NPCs. There are two primary spots in Bal Foyen where they spawn quite frequently regardless of how many people seem to farm the spawns.
We recommend the spot by the coastline as that spot tends to be less populated. Depending on how heavily populated these farming areas are, it's always safe to group up with others in Zone Chat as their kills can also count towards granting your loot as long as you're in proximity.
For the specific farming pattern, refer to the video below:
This Lead only drops from fishing Foul Water nodes in Murkmire. We recommend the northern area as it's not too populated and has frequent spawns unlike Artaeum's fishing holes for one of its five Thrassian Strangler Leads.
No matter who you are, you've most likely heard about this rather daunting Lead that can only be found by harvesting water-based nodes in the zone of Shadowfen.
Whether camping a node or going around to take nodes we offer the following maps of Shadowfen with all the node spawns courtesy of Shinni's HarvestMap addon.
If the zone becomes heavily populated with everyone camping each node spawn, it's more efficient to camp a node spawn. Otherwise roam around.
Note that water-based nodes include: Water Hyacinth, Nirnroot, Pure Water nodes and Water Sacks.
A very good farm route can be found in Sanguine's Demesne, the Shadowfen Public Dungeon which has quite a few Water Sacks in it. The Public Dungeon counts as being part of Shadowfen and can drop the Tide-Glass Beads Lead.
