Akhelian Beastmasters is one of the four core Idoneth Deepkin battle formations in Age of Sigmar 4th edition. It rewards leaning into the faction's iconic sea-beast cavalry by making their mounts hit harder. This is an original summary; confirm the exact wording and any conditions in your current faction pack.
What the formation does
It adds 1 to hit rolls for combat attacks made with the companion (mount) weapons of friendly Akhelian units. Because a lot of Idoneth cavalry damage comes from the eels and sharks themselves rather than the riders, this is a clean, always-on boost to your core threat. Confirm the precise wording in your book.
Who it suits
Players building around Akhelian cavalry - Morrsarr Guard, Ishlaen Guard and Allopexes - who want their mounts to land more of their attacks every combat, not just on a special turn.
Key units
- Akhelian Morrsarr Guard - more mount hits stack neatly with their charge burst.
- Akhelian Ishlaen Guard - improved output while they pin and tank.
- Akhelian Allopex - a big beneficiary, as much of its damage is the shark itself.
- Akhelian King / Volturnos - lead the eel line and share the cavalry theme.
When to pick it
Pick it when your list is genuinely cavalry-led. It's a reliable, low-variance choice that improves your army every turn rather than gating its value behind a specific tide or trigger, which makes it a comfortable default for eel/shark builds.
Common questions
Does the +1 to hit apply to the riders' weapons too?
As reported, the bonus is for the companion (mount) weapons specifically, not the riders' own weapons. Since a large share of Akhelian damage is the mount, it's still very impactful - but check your warscrolls and the formation's exact wording.
Is Akhelian Beastmasters a safe default pick?
For a cavalry-heavy Idoneth list, yes - it's an always-on damage boost with little downside. If your list skews toward Namarti infantry or magic instead, another formation may suit you better.
