Chilling Assault

Luna Snow grants Winter's Chill to Iron Fist and Emma Frost. When Iron Fist activates Harmony Recovery, he can heal nearby allies with Lunar Chi. Emma Frost can project ice energy forward, dealing damage and slowing enemies. She can also enhance her diamond form, condensing frost into an Absolute Zero Diamond barrier that blocks enemy attacks and movement.

This Team-Up was first introduced in Season 2.5 and received an update in Season 5 and Season 5.5.

Lore

Luna Snow: Whoa, Hawkeye! That last arrow... did you see the ice trail it made? That was seriously cool, right?

Hawkeye: Oh, I saw it. Tell me straight. Did you mess with my quiver when I wasn't looking?
Luna Snow: Guilty! I just gave your arrow a little drip. Gotta keep things fresh for the fans! Plus, keep the bad guys on ice!

Hawkeye: Do you always talk like that? Don't go turning our missions into one of your concerts now.

Luna Snow: Please, I'm a legit hero first! But hey, a little style never hurt, right? You always look so serious. Gotta help you get rid of that icy exterior. Yeesh!

Hawkeye: I don't rely on style, I rely on precision. But… I'll admit, it was a nice touch. Thanks.
Luna Snow: Anytime! Even though you've been a hero for so long, your accuracy is still top of the charts! I'll just give it a little extra pop!

Hawkeye: ...Alright. But next time you want to "remix" my arrows, give me a heads up. I might look grumpy, but I'm not that scary.

Luna Snow: Deal! And hey, if you ever need to cool off, just call me—I'll be there in a flash!

Chilling Assault Guide

Iron Fist

With this Team-Up ability, Iron Fist becomes more than just an aggressive damage dealer, he turns into a strong team player. When he activates Harmony Recovery, he heals not only himself but also nearby allies.

To get the most value out of this Team-Up, avoid using Harmony Recovery when you're isolated. Instead, position yourself in the mid or backline so teammates who need healing can move closer to you. Acting as a healing anchor adds tremendous utility to your team.

Best Against

This Team-Up works best against Vanguards and heroes who like to dive into your backline to pressure your Strategists. Since Iron Fist is naturally strong at shredding tanks, he can handle diving Vanguards while healing nearby allies at the same time.

Best Counters

Heroes who can stun Iron Fist before he activates this Team-Up are some of the best counters. Aside from that, heroes who apply anti-heal effects, such as Blade and Gambit, are also effective, as they can greatly reduce the value of Iron Fist’s passive healing for his teammates.

Emma Frost

Emma Frost becomes even more chilling with this Team-Up. When activated, she creates an ice wall that blocks enemy attacks and movement. While the wall is active, her basic attacks gain a chilling effect, slowing enemy movement on hit.

This ability is extremely effective for isolating enemy frontliners from their healers and punishing overextended enemies. Place the ice wall carefully to cut off healing access, trap low-health targets, or deny escape routes during team fights.

Best Against

This skill works best against enemy frontliners who need to get close to deal damage. Melee heroes with limited mobility should be your top priority targets when using this Team-Up.

By cutting them off from their backline, you can deny the healing they rely on while diving. Proper timing and placement will make these frontline dives extremely punishing.

Best Counters

Flying heroes such as Ultron, Iron Man, and Storm are the most effective counters to this Team-Up skill, as the ice wall does not restrict aerial movement.

Captain America and Angela are also strong answers thanks to their high mobility, allowing them to quickly reposition and move around the wall without getting trapped.

Among Strategists, Rocket Raccoon stands out as the best counter pick. By taking high ground positions, Rocket can continue applying consistent healing to allies caught behind the wall, greatly reducing its impact during team fights.
