Age of Sigmar Tactics

The power of summoning in Age of Sigmar

Summoning is a great and misunderstood tactical tool in Age of Sigmar. It lets you adapt your army on the fly, allowing for some crazy flexible and strategic plays.

In this AOS tactics article, I will explain the fundamentals of summoning and how you can us it to kick butt.

My goal is not to tell you what to do, but to increase your understanding of the game so you can make better choices.

What is summoning

In AOS, Summoning is the ability to set-up a new unit on the table through a spell or ability.

You can summon plenty of units in Age of Sigmar. Usually, the spell that allows you to summon a unit can be found on the summoned units war scroll. All wizards from the faction know these spells unless the war scroll says otherwise.

For example, all Death wizards can summon Skeleton Warriors while only Slann wizards can summon Skinks.

Most summons have the same restrictions, they must be setup within 18″ of the caster and 9″ away from any enemy models. In most cases, these units are not allowed to move in the movement phase of the turn they come into play.

When you summon a unit you will have to pay for it with points from your “reserve pool”. You determine the size of your reserve pool on your army list. Your reserve pool counts towards the total point value of your army.

Some spells allow you to place more models if you get a higher cast result. It is important to realise that it only raises the number of models that you can set-up, it does not force you to.

Summoning offers Flexibility

The biggest strength of summoning is the flexibility it offers. Summoning allows you to set up a unit of your choice pretty much where ever you like. This means that you are not as limited by your army list as your opponent, allowing your to adapt to the way the battle unfolds.

This does not only allow you to counter your opponents actions, it stops your opponent from predicting your moves. When your opponent can not predict your actions, you can dictate the flow of the game.

Since you can strike virtually anywhere, you force your opponent to play defensively. In an objective based game that is huge. I can not stress enough how powerful that is.

I can not stress enough how powerful that is.

Location

Most summoned units must be placed within 18″ of the summoner and 9″ away from enemy models.

It is important to note that a unit is within’ a certain distance of something else as long as the shortest distance between the two units is equal to or less than the stated distance. This was stated in this F.A.Q.

This means you can set-up your summoned models however you like as long as they stay in unit cohesion, allowing you to reach a lot further than the 18″.

By setting up 2 of my 10 Skeleton Warriors a bit closer to the Necromancer, I was able to set up 8 skeletons 24″ away from my Necromancer. This way I can reach all the way across the table into my opponents deployment zone.

This allows you to capture objectives, prepare devastating charges or deny the movement of enemy units. You can read more about area denial and zoning here.

Balewind Vortex

The Balewind Vortex is a summonable piece of terrain that costs 100 reserve points. It allows the caster to stand on top of a magical vortex that increases its casting rolls by 1 and doubles the range of its spells, allowing you to set-up summoned units within 36″ of the caster.

When the Balewind Vortex is summoned, all models around it need to be moved so that they are not within 3″ of the base of the Vortex. Since the base of the vortex is roughly 4″ in diameter, you can use it to push friendly models in a direction of your choice.

For example, you could summon a Bloodthirster 9″ away from the enemy and behind the Bloodthirster, you could summon a Herald of Tzeentch. When this Herald summons a Balewind Vortex it can push the Bloodthirster forward up to about 5″, putting it very close to your enemies!

The Balewind Vortex can be removed from play at the beginning of the hero phase and summoned again by the same or another wizard from you army at no extra cost.

This gives you so much flexibility that it doubles the potential threat range of all your casters, making it very hard for your opponent to predict your actions.

By having enough points in reserve for a Balewind Vortex, you already put a lot of pressure on your opponent.

Overruling Restrictions

All armies can include a limited amount of heroes, behemoths and artillery on their army list. With summoning, you can override those restrictions, since you do not have to specify what you will summon on you army list.

It even allows you to break allegiance without losing its benefits. This allows for some amazing flexibility in your list building. For example, it would allow a pure Tzeentch army to summon a Bloodthirster without losing its use of destiny dice.

Reducing Deployed units

Every unit that you summon during the battle does not have to be set-up during your deployment. This can allow you to finish your deployment earlier than your opponent, giving you the choice for the first or second turn.

Having the choice of the first or second turn enables you to determine the development of the battle and who gets the first chance for a double turn.

Double turns are especially good for summoning since most summoned units cannot move in the turn the are set-up. Read more about the deployment or the double turn.

Summoning Support Units

Summoning goes far beyond the offensive. It is about controlling the battlefield, knowing what the place where and when to do it. Support units play a huge role in this.

Death has some great ways to mitigate shooting damage by summoning Bat Swarms, Chaos can summon a Blue Scribe for re-rolls on casting attempts, Order can summon an Astrolith Bearer for increased casting results etc…

It is important to note that summoned casters can cast spells on the turn they are set-up. This means that your summoned summoners can immediately start summoning. Even though this is quite a tongue breaker, it allows for some nifty plays.

The great thing about summoning support units is that you only have to pay for them when you need them, allowing you to field a more efficient army.

Finding the right support units that you can summon is a process of trial and error. Look at the weakest points in your army, in offence and defence, and see how these specific units can make things a bit better. Test your ideas and improve on them where necessary!

Physical models and their Psychological value.

Unless you are heavily proxying, you will need to have the physical models you want to summon. Even though this brings some extra costs and effort, having the models also brings one huge benefit. You can use them to pressure your opponent, just like you would by showing or hiding your fake money during a game of Monopoly.

The models that your opponent can, or can not see, will influence the decisions they make. Knowing that you could summon a Mourngul will force your opponent to brace for impact, knowing that you could summon a Balewind Vortex forces them to think about your threat range.

You can influence the way your opponent plays by showing what you can summon. For example, by placing a Mourngul and a unit of Morghast Archai next to the table, your opponent will probably suspect you to summon one of those.

This could motivate your opponent to protect against big models while you planned to flood them with loads of small ones.

The downsides of summoning

Summing is great, but it has some heavy limitations that you need to deal with to use it efficiently.

Rule of 1.

With the rule of 1, each spell can only be attempted once every turn. You only get one try per summon and you cannot summon the same unit multiple times in one turn.

This means that you need a relevant unit to summon for each spell you can cast. This might mean that you need quite a few more units than you can actually summon. When building your army list, look for different summonable units that can fulfil the same roll so that you can try with a different unit if you summons fail.

Summons can fail or be dispelled

The fact that spells can fail or be dispelled tends to give a feeling of unreliability to summoning. Luckily, there are plenty of ways to boost your spellcasting.

Every faction has some ways to increase the results of your casting or allows for re-rolls. There are also plenty of characters that are inherently better at casting spells than others. Such as Kairos Fateweaver, Arkan the Black, Wierdnob shamans etc.

Because summons can fail and only be attempted once, it is a process of risk management.

Before you start your summons, look at the whole picture. What part of your army needs to be protected, what part of the enemy must be pressured and what objectives need capturing. What will happen if you fail your summons and how can you deal with it?

Summon the most important units first, and use the casters that can get them on the table with an 80% cast chance.

On this table you can see the chance your casts will succeed. It includes positive roll modifiers and a table for re- rolls. As you can see you need +5 on your to your casting rolls or +3 and a re-roll to get a reliable 10+ summon of.

Summoners can die

The more you rely on summoning units, the more important your summoners become. Summoners can die, and if your last summoner dies before you have depleted your reserve pool, you practically lose all those points. So it speaks for itself that you need to protect your summoners and keep them out of your opponents threat range.

Against most armies, this is not a problem, but vs shooting heavy armies it can be hard. If your opponent can easily kill all your casters in one turn, it can be smart to summon another wizard or force your opponent to choose between other threatening targets.

By summoning a threatening unit in a key location that needs to be dealt with, you give your opponent a difficult choice. If they do not focus on the threat they will suffer heavy casualties, if they do not focus on your summoners there are plenty more to come. Quite a pickle you will put them in!

Even though the Freeguild Handgunners can’t attack my Necromancers, the three Cannons can kill them quite easily. Most of the units I summon will get shot down, but I know one particular monster that is pretty beefy.

By summoning my Balewind Vortex I was able to summon a Mourngul 36″ away, putting it right behind the Cannons and Handgunners. Since a Mournghul has a 3+ save that ignores rend and a 4+ ward save, my opponent must focus all its firepower on it to mitigate its damage output.  My Necromancers live to fight another day!

This will hardly ever be a problem since there are few reliable ways to kill multiple heroes in one turn, but it is good to know you could to deal with these situations.

Limited choices of summonable units

Another limitation to summoning is the limited amount of different units each army can summon. When writing your army list you should try to figure out how your existing army can work together with wat you can summon. Figure out what the weaknesses of your casters and battle line units are and how you can fix them with summonable units.

Just like with any list, it is a tough process of trial and error.

The pains of a 9″ charge

Since you must set-up most summoned units 9″ away from enemy models, it can be hard to make the charge. You will only be able to make a 9″ charge about a third of the time, making it very unreliable.

If it is important that you make a specific charge, you should improve their charge chances with some buffs or have multiple units that can attempt the charge. You can read more about charging here.

Summoner efficiency

Summoning allows you to do all these amazing things, but it also needs a unit that can summon them. Summoners are, in relation to the units they summon, quite expensive. When choosing a summoner and their support, it is important that you weigh their point costs against the benefits you will get out of it.

Do this by looking at what each potential caster brings to the table besides their ability to summon. On average, wizards cost about 100 points per spell they can cast.

For example, Arkhan the Black costs 340 points and can cast 2 spells. As long as he suffered no wounds he also gets +3 on any spell that summons death units. This makes him pretty efficient. That he can hold his own in combat is a bonus. Looking at this you can conclude that Arkhan is a great choice as a dedicated summoner.

A Necromancer costs 120 points and can cast 1 spell. They also know the spell Vanhel’s Danse Macabre, which lets one death unit within 18″ pile in twice. Using a Necromancer to summon would mean that you can’t cast Vanhel’s Danse Macabre. Necromancers are mediocre dedicated summoners but are great as support after one or two summons.

When picking summoners, look at models that can cast multiple spells or have other things to offer besides their spellcasting.

It is important that you pick a summoner that stays relevant once your reserve pool is depleted.

Gryph-hounds

Summoning does not have too many hard counters, but Order Gryph-hound are definitely one of them.

Whenever an enemy unit is set-up within 10″ of an Order Gryph-hound all units within 2D6 Inches of the Gryph-hound can shoot their missile weapons at the set-up unit.

This means that your opponent can use a few Gryph-hounds to effectively stop you from setting up units on objectives and near key targets. Try to kill these bird dogs as soon as you can or force your opponent to split them up.

Even though Gryph-hounds have great potential, they are quite situational and there for rarely used by most players.

    Could you elaborate on why subsequent summons of the Balewind Vortex do not cost reinforcement points. I ask because the Generals hand book specifically says “each” time a unit is summoned you must pay the reinforcement cost, as opposed to the “first” time or a “new” unit is summoned.

    Cheers for the articles by the way, they are an informative and very enjoyable read. 🙂

      Hi! I am happy you like my articles, thanks!

      This is a tricky one. My reasoning goes as follow: because the model is removed by the owner and not killed, it is safe to assume it works the same way as other units that get removed from play and setup again.

      If you would “lose” the model when it is banished, why would it state that it is removed from the battlefield until it is summoned again.
