Idoneth Deepkin: Army Analysis

Who are the Idoneth Deepkin?

The secretive sea-aelves of the Mortal Realms, the Idoneth Deepkin rise from the ocean depths to raid for souls, then vanish back beneath the waves before anyone can answer. They ride savage Akhelian eels, summon ghostly sea-mists, and unleash monstrous deep-sea beasts. In Warhammer Age of Sigmar they're an army of ambush and timing — patient, then suddenly, devastatingly violent.

The Core Fantasy

Idoneth Deepkin are the ambush army of the Mortal Realms: a force that holds back, picks its moment, then crashes over the enemy like a breaking tide. This is the fantasy of the deep-sea raid — eerie, beautiful and brutal, built around hard-hitting cavalry and monsters that arrive exactly when it hurts most.

Expect:

• A signature tide mechanic that rewards careful timing
• Fast, hard-hitting eel cavalry as your stars
• Monstrous sea-beasts and striking centrepiece models
• Mind-tricks and mists that blunt the enemy's response

How They Play on the Tabletop

The Idoneth plan is patient aggression: weather the early turns, use mists and ambush to protect your force, then surge forward when your tide peaks and shatter the enemy in a single decisive wave. Get the timing right and you hit like a freight train at the perfect moment; get it wrong and you can be caught flat-footed.

What you'll love:

• Alpha potential: a well-timed strike can win the game outright
• Mobility: fast eels let you choose your fights and reach objectives late
• Tricks: mists and abilities limit how hard the enemy can hit back

What can bite you:

• Timing-dependent: mistime your tide and the whole plan wobbles
• Fragile infantry: your foot troops don't soak punishment well
• Lower numbers: a smaller force can struggle to be everywhere at once

The Tide Comes In

The Idoneth signature is the ebb and flow of battle — a tide that shifts the army's strengths turn by turn, from defensive caution to all-out assault. Mastering when to weather the storm and when to unleash the wave is the entire art of the army, and it makes them one of the most satisfying, skill-rewarding forces in the game.

They're aelves, kin to the realms' other elegant, fragile-but-deadly factions. For another fast, glass-cannon aelf army, see our Daughters of Khaine army analysis; for the disciplined, magic-rich aelves of the light, compare the Lumineth Realm-lords.

Key Unit Roles (What You'll Commonly Need)

Forget memorising every warscroll. Think in jobs:

1) The Line (Namarti infantry)

Thralls and Reavers to hold objectives and screen — your affordable, if fragile, foot soldiers.

2) The Hammer (Akhelian eel cavalry)

Fast, hard-hitting eel riders who deliver the decisive charge. The deadly heart of the army.

3) The Monsters (sea-beasts and Eidolons)

A Leviadon or Eidolon to anchor the line, hit like a tidal surge, and serve as a stunning centrepiece.

4) The Heroes (kings and casters)

Akhelian Kings, Soulscryers and Tidecasters who buff your charge, manage your ambush, and cast mists.

Getting Started the Smart Way

Building Idoneth Deepkin from scratch? Build around your eels and a strong centrepiece. Aim for:

Step 1: A unit of Namarti Thralls

• Your objective-holding foot troops. Affordable bodies that free your eels to do the killing.

Step 2: A unit of Akhelian eels

• Your fast, hard-hitting hammer — the unit your whole army is built to support.

Step 3: A monster centrepiece

• A Leviadon or Eidolon to anchor the army and give the enemy something to dread — a glorious paint project too.

Step 4: A hero or two

• Leaders to buff your charge and manage your ambush and tide. The brains of the operation.

Cover those four jobs and you've got a fast, hard-hitting army that plays to its strengths. New to the brushes? Our beginner painting guide will get those deep-sea teal-and-pearl schemes started.

Common Beginner Mistakes (Avoid These)

• Striking too early. Patience is power — wait for your tide to peak before committing.
• Exposing your infantry. Fragile foot troops need cover and screening to survive.
• Forgetting your tricks. Mists and abilities are key to surviving the approach — use them.
• Ignoring objectives. A devastating charge still loses if nobody is holding the points.

Who the Idoneth Deepkin are For

"Choose the Idoneth Deepkin if you love timing, ambush and a beautiful army that strikes like a breaking wave — patient one turn, devastating the next. Give them a miss if you want a forgiving, straightforward army or lots of durable bodies; this is a precise, skill-rewarding force. Idoneth reward patience, careful timing and clever use of your tide. Wait for the moment — then drown them."
