Get Brinedeep Bottom-Feeder mount

The Brinedeep Bottom-Feeder is an aquatic mount from the Legion expansion that can be purchased from Conjurer Margoss for Drowned Mana. The mount is a deep-sea anglerfish that your character rides underwater. Obtaining it requires patience and fishing skill — the entire process revolves around fishing.

• One of the few aquatic mounts in the game available without a random drop — the result is guaranteed.
• A unique deep-sea anglerfish model with its signature lure light.
• Counts toward mount collection achievements.
• Acquisition doesn't depend on luck — the farm is predictable and finite.

• A character that is level 10 or higher.
• Riding skill Apprentice or higher.
• The Fishing skill (any level — Drowned Mana can be caught at any skill value).
• Best Friend reputation with the Conjurer Margoss faction.
• 100 units of Drowned Mana to buy the mount (on top of what goes toward reputation).

Margoss's Hut is a hidden floating island northwest of Dalaran in the Broken Isles. The island is not marked on the map. There are three ways to get there:

Method 1: Flying (the most convenient)

If you have flying unlocked in the Broken Isles (the Broken Isles Pathfinder, Part Two achievement), simply fly out of Dalaran to the northwest. The island floats a short distance away.

Method 2: Emblem of Margoss

Fish up the Emblem of Margoss from the Whirlpools in Dalaran's Underbelly, near the Black Market:

The emblem is a consumable item that teleports you straight to the island.

Method 3: Gliding

Go out onto the ledge between the Violet Citadel and the Magus Commerce Exchange:

From there, glide to the island using one of these options:

• Demon Hunter — Glide
• Any class — Goblin Glider Kit

Step 1: Reach Margoss's Hut

Use one of the methods from the section above. On your first visit, walk up to Conjurer Margoss — he stands by the fishing hut on the island.

Step 2: Complete the Introductory Quest

Margoss will offer the quest Drowned Mana, which requires you to fish up and turn in 1 unit of Drowned Mana. This quest grants you 250 reputation points — a one-time bonus.

Step 3: Fish Up Drowned Mana

Cast your line into the little pool right in front of Margoss's hut. Drowned Mana can only be caught here and only on this island. Each cast can yield between 0 and 2 units of mana.

Step 4: Turn In Mana for Reputation

Give Drowned Mana to Conjurer Margoss:

• 1 mana = 50 reputation points
• 10 mana = 500 reputation points (it's more efficient to turn in batches of 10)

Step 5: Grind Reputation to Best Friend

The Conjurer Margoss faction has six reputation levels, each requiring 8,400 points:

The total amount of mana to reach Best Friend is roughly 835 units (accounting for the introductory quest). With a 10% reputation bonus, you'll need about 759 units.

Step 6: Buy the Mount

Once you reach Best Friend reputation, talk to Conjurer Margoss and buy the Brinedeep Bottom-Feeder for 100 units of Drowned Mana.

In total, the whole journey will require roughly 935 units of Drowned Mana (835 for reputation + 100 for the purchase).

Mark of Aquaos — the Key to Fast Farming

Roughly 1 in 100 casts, instead of Drowned Mana you'll catch a Mark of Aquaos. Throw it into the lake and the elemental Aquaos the Unleashed will appear. Defeat it, and the lake will fill with energy for 2–3 minutes: during this time every cast is guaranteed to yield 1–2 units of Drowned Mana.

Before activating the Mark of Aquaos, put on your combat gear instead of your fishing pole so you can kill the elemental quickly and not waste the buff time.

Group Farming

The most efficient method is fishing in a group of 10–40 people. When several players fish at once, Marks of Aquaos appear more often and the boss is kept up almost constantly. In an optimal group of 20+ people, the entire farm takes 2–3 hours.

Look for groups through the Group Finder (Premade Groups / Custom search) using the queries: "Margoss", "Drowned Mana", "fishing".

Solo Farming

When farming solo, expect 8–12 hours of total time. Without an active boss, Drowned Mana is caught less often — about 1 unit per 3–5 casts.

Reputation Bonuses

Use any available bonuses to speed up the grind:

The bonuses don't stack with each other (except the racial one), so pick whichever is most convenient.

Class Recommendations

Absolutely any class works for farming — you barely need to fight, and the elemental Aquaos goes down in a few seconds at current content level. If you're creating an alt specifically for this — a Human will provide a +10% reputation bonus.

While you grind reputation, take a look at his other goods:

Buying all of the items requires roughly 1,235 units of Drowned Mana (reputation included).
