Isharann Council is one of the four core Idoneth Deepkin battle formations in Age of Sigmar 4th edition. It's the magic-focused option, rewarding lists that field multiple Isharann and want to lean on spells and rituals. This is an original summary; confirm the exact wording, ranges and any conditions in your current faction pack.
What the formation does
It adds 1 to casting rolls and to Isharann ritual/lurelight rolls for friendly Isharann units while they are near other friendly Isharann units. In short, your wizards get better when they work as a group. Confirm the precise triggers and ranges in your book, as these details are easy to misplay.
Who it suits
Players who enjoy a magic-heavy Idoneth build and want to reliably land spells, rituals and support effects. It suits lists with several Isharann casters clustered to feed the bonus.
Key units
- Isharann casters (Tidecaster/Soulscryer types) - the direct beneficiaries; more casters means more overlap.
- Eidolon of Mathlann (Aspect of the Sea) - a caster-leaning centrepiece that fits a magic plan.
- Any units your spells/rituals buff - the payoff for landing more of your magic reliably.
When to pick it
Pick it when magic is a real pillar of your list, not an afterthought. Community coverage generally views it as more niche than the mobility- and cavalry-focused formations, so it earns its place mainly in dedicated caster builds. Confirm current effects before committing.
Common questions
Is Isharann Council competitive?
It's usually seen as the more situational of the four core formations, best in a genuinely magic-heavy list. If you only run one or two casters, the cavalry, Namarti or mobility formations tend to give more consistent value. Check recent coverage for the current view.
How many casters do I need for it to pay off?
Because the bonus keys off Isharann operating near each other, you generally want several casters so the buff is reliably switched on. One lone wizard won't get much from it. Confirm the exact proximity requirement in your faction pack.
