Keystone Rune guide: How to use Summon Aery

Summon Aery is a weird mix between support Keystone and Mage Keystone. It goes great on champs that deal damage and have shields, regardless of if you’re playing them mid or bot.

What does it do?

When you use an ability, Aery will venture forth and do one of two effects. If your ability damaged an enemy, Aery will deal additional damage to them. If your ability healed or shielded an ally, Aery will fly to them and add a shield.

Which runes go well with it?

Summon Aery is a versatile rune for lots of different champions. As a result, we’re gonna grab a variety of runes that help in almost any situation.

The Ultimate Hat is great for any champion. The more frequently you use your ultimate the faster it cools down. Most of the champions you want to use Summon Aery on have game changing ults. Whether it’s Shockwave, Final Spark or Crescendo, this rune will help you out.

Transcendence will continue to help you cooldown your ultimate faster as well as your other abilities. Even better, it converts CDR into AP after you’ve hit the cap. That's especially great if you love items with CDR and get sad every time you hit the cap. Be sad no more.

Scorch is going to add some extra damage to help secure your kills. While that may not sound desirable on a support, the ability to kill secure on high damage supports is far better than letting that low health Varus just walk away.

The Inspiration tree is gonna be secondary for us here. For these kinds of utility based champions, you want to increase your in lane sustain and cooldown. For in lane we want to grab the Biscuit Delivery to help keep us full of mana. For later in the game we want to get Cosmic Insight, which pairs very nicely with Transcendence.

Who’s it for?

Summon Aery is perfect for your non-burst utility mages. If you can shield or heal and also do decent damage, this rune is for you.

You want to take this rune on champions like:

• Lux support
• Orianna
• Karma
• Lulu
• Sona

This rune won’t serve you well if you want to use Lux as a burst mage. However, Lux support, Orianna, Karma and others are perfect here. With this particular build, Orianna should be able to move the ball and shockwave extremely often. The same goes for anyone else on that list.
