The odd turns of Low Tide
On turns 3, 5, 7 and following, Merkator pulls, at the start of its turn, all characters in line with it up to its contact, up to 12 range, and removes 4 MP from them. On contact, Ice Ageing removes half of your vitality for one turn: never end these turns in its line.

His spells have very little range: at range, he is almost harmless. But he reduces damage taken at range by 50% and gains 2% final damage with each hit received from afar, and all enemies are unmovable. Air is the element he handles worst.
Ice AgeingOn contact, twice per turn: the target loses half its vitality for one turn and goes into Gravity.
Bronze AgentLine of 5 cells, in a line up to 3 range, once per turn. Reinforced with each hit you deal him under Bathyscaff.
BathyscaffFrom turn 2, recast every 2 turns: it strengthens Bronze Agent and prepares Low Tide, the pull of the next turn.
Mouth to MouthFrom turn 7, recast every 5 turns, without line of sight: it revives the last dead ally with half its HP.
The four-step strategy against Merkator
As far as possible from Merkator. While you kill the monsters, move as far as possible from the boss and get out of his line before every odd turn. A summon placed near him keeps him busy: he often prefers to hit it rather than come to you.
The Bartyclank first. When hit at range under Glory Hunter, it gives MP and damage to its allies placed far from it. Kill it first and fast, in one turn if possible, or hit it when the boost is absent or its allies are near it.
The Harpo next. From turn 2, Happy Camper strengthens its Drip-Dropshot of the following turn. On that turn, stay out of its sight or within 5 range of it: the spell only reaches from 5 to 12 range. The Barbakle dies in one go once it is chipped, the Psychlo last.
Merkator alone. Two options: wear him down at range, slowly because of his 50% reduction, or hit him in melee to finish fast. Either way, beware of the turns when he is under Bathyscaff, the only time he becomes truly dangerous.
Sea Worthy and Sea Legs
From the start, Sea Worthy makes Merkator and all his monsters unmovable for the whole fight, and reduces the damage Merkator takes at range by 50%. Each hit received from afar also gives him 2% final damage.
Sea Legs punishes every attempt to remove MP from a monster: the caster takes about 500 Fire life-steal damage. The fight goes very well without MP removal; otherwise, a Feca protection (Ataraxia, Bastion, Aegis) avoids this damage.
Bathyscaff
From turn 2 and every two turns after, each damage he takes increases Bronze Agent's base damage by 30, up to five times, for one turn. Do not hit him under this effect if you risk being hit afterwards. The following turn, Low Tide pulls the whole line.
Move the unmovable with Sea An Enemy
Hitting a monster in melee pushes back 3 cells its allies placed in a cross around it, despite the unmovable state, and your characters placed diagonally. Hitting an ally with a weapon pushes back 3 cells the monsters diagonally around it and your characters in a cross.
Handy for moving Merkator away, but never essential: the dungeon is very accessible without moving anyone.
The monsters of Merkator's Aquadome
Five level 200 Merkaptans, each with a -29% weakness in a different element. Several hit based on their missing HP: a chipped monster is finished off within the turn. Resistances in red are their weaknesses.
In which order to kill the monsters
- Bartyclank — when hit at range, it gives MP and damage to distant monsters, and its glyph kills.
- Harpo — its strengthened Drip-Dropshot from turn 3 deals enormous damage at long range.
- Barbakle — it pulls the whole team and hits almost the entire map depending on its missing HP.
- Steamcrab — it pulls in a line and punishes ranged attacks under Pinception.
- Psychlo — the least dangerous, kept for last.

Preparing your run through Merkator's Aquadome
An easy dungeon for teams of level 190 to 200, as long as you handle the lines and the ends of turn. People come for Spinning Around, Don't Drink the Water and the order quests, the achievements, and for the capture with a Soul Stone for Gigantic Souls (captures up to level 220).
How to enter Merkator's Aquadome
The entrance is in the Abyss Rooms, at the bottom of the abyssal base of Sufokia Bay, at ; the nearest zaap is the one at Sufokia . To go down there, you must have defeated Armagudgeon, then Quartermaster Biscotti, who unlock their elevators, and Foggernaut Batteries open some passages. Then: a Merkator's Aquadome Key (consumed), the keyring, or the automatic group search.
Crafting the Merkator's Aquadome Key
It is crafted at a handyman. Five ingredients drop from the dungeon's monsters, at 12%: Bartyclank Leather, Steamcrab Carapace, Barbakle Barb, Psychlo Beard and Tasty Meat. Icefish (fishing), Snowdrop and Frosteez (harvesting) complete the recipe. Spinning Around also gives one.

Which team to bring against Merkator
No MP removal without protection. Each removal attempt costs the caster about 500 HP. The fight is won very well without removal; otherwise, protect yourself first with a Feca spell.
Something to hit in melee. Merkator halves ranged damage. One or two characters able to hit him hard on contact shorten the end of the fight a lot; plan some healing or protection then.
Summons. A summon placed near Merkator pulls it away from your team while you clear the monsters.
Classes that are comfortable here. The Feca removes MP without suffering Sea Legs thanks to Ataraxia, Bastion or Aegis. For the rest, any composition gets through: it is an easy dungeon, where melee hitters finish Merkator faster.
The six achievements of Merkator's Aquadome
Each achievement gives 200,000,000 XP and 2 Merkator's Beard, Duo doubles the XP; Sidekick gives 75,000,000 XP. Last and Mystique do not complicate the fight: do them together with the Special on the first run.

Last
Merkator must be finished last. That is already the basic strategy: the fight is even simpler if you respect it. Just watch out for indirect damage that could finish him too early.
Mystique
Deal only spell damage and spell heals during your turns. No weapons. You lose one of the ways to move enemies with Sea An Enemy, but it is not needed to win.
Special: Always Someone There to Align Me
Each ally must start or end their turn in line with an enemy. End each turn in line with a monster, but not with Merkator while his monsters are alive: Low Tide would pull you. Once he is alone, you will be forced to end in line with him and he will pull you sooner or later: hit him in melee, which is more effective and does not strengthen him.
Duo
Two characters maximum, fewer than 40 turns. Any composition can do it. Bring enough damage to take down the monsters quickly, then circle around the map hitting Merkator until he dies.
Sidekick: Garbage Pail Sidekicks
At least four characters, including one allowed sidekick: Grute, Goboff, Rint or Piggy Paupe. The sidekick can play it safe: it just has to be in the group that wins the fight.

Merkator's Aquadome as a guild Expedition
The Aquadome exists as two guild Expeditions, Audacious and Valour, each with its modifier:
- Audacious: the monsters share their damage, Merkator excluded, and each hit gives 2% final damage, for the whole fight, to the monster hit and its attacker;
- kill the monsters first by hitting in an area and target the one that fears your element: its resistances guide the split. The bonus is only triggered by the direct target;
- you keep your acquired final damage: Merkator afterwards is simpler than usual;
- Valour: Merkator is invulnerable for the whole fight. Moving him with Sea An Enemy makes him vulnerable until the start of his next turn, but gives him 1 MP until the end of the fight;
- kill the monsters first. Then, place your first character in initiative diagonally from Merkator at 3 range or less, and hit him with a weapon with the next one to move the boss early in the turn;
- each additional turn adds one MP to him: finish him quickly, preferably in melee.
