Aftershock is the kind of rune that won’t make or break your team but it will come in handy. This will be nice on your big boy tanks and your powerful CC supports. Just stay near the enemy once you get your CC off and try your best to stay healthy.
What does it do?
Applying CC to an enemy champion increases your defenses momentarily. After a few seconds, an area of damage will erupt around your champion. This area deals damage to everything around you based partially on your max health.
Which runes go well with it?
Aftershock is for the CC bots of the world. If you’re able to easily lock down a champion but struggle on the damage end, this is a perfect addition to your toolkit.
Font of Life is our first extra rune. This doesn’t necessarily help us, but it will help our allies. The goal with most of these champs should be to help peel for our AD Carries and mid laners. Passively healing them is a great addition.
Since most of these champs have some kind of healing built in, Iron Skin will help in lane or out. We’ll counter this with a MR defense later as well. Second Wind will act as a miniature Warmog’s Armor, which is something champions who use Aftershock will desperately need. As a bonus, it’ll proc Iron Skin.
Sorcery will be our secondary tree. Our first rune here will be Nullifying Orb, which will help cover the magic portion of incoming damage. Gathering Storm will work nicely to give us some passive damage as well.
Who’s it for?
Aftershock is for your CC bruiser and occasionally for your tanky support. This rune doesn’t seem revolutionary or particularly game changing, but it will help add some extra AoE damage to your fights.
You want to take this rune on champions like:
Leona is a pretty obvious choice here. Any time she is doing her job, she’s in the thick of things and ready to jam. Sion, Maokai and Galio all have short ranges or no range at all, which also makes them prime candidates for Aftershock.
