Alongside the new field, Axion Plains, The First Descendant introduced the largest Colossus intercept battle yet. Wall Crasher intercept battle is an eight-player event you can participate in to try and get a bunch of rewards, including the new Trigger Modules.
Wall Crasher appears every hour on the hour (at 00 minutes) in Axion Plains, and you must enter the fight within five minutes by approaching the central structure in the field. This puts you into matchmaking and loads you into an instance with seven other players.
Here’s everything you need to know about Wall Crasher in The First Descendant and how to beat it.
How to defeat Wall Crasher in The First Descendant

While it’s a long fight, Wall Crasher isn’t mechanically-heavy. The boss has multiple large weak points that are easy to aim at and shoot, including its shoulders and balancers on the knees. Wall Crasher has many attacks, but most of them are only a threat when you’re on the ground.
The only mechanic is with purple pillars that create an AoE damage zone. They deal high damage (so stay out of them), but when you destroy all the pillars, the boss becomes dazed and takes increased damage, so use that to speed up your fight.
In the Wall Crasher fight, you don’t fail the mission when the death count hits zero. You can still respawn, but with reduced resurrection effects.
Best loadout to fight Wall Crasher in The First Descendant

Unlike other bosses, Wall Crasher has the same resistance to all attributes (Pyromaniac, for example, is weak to Chill). This means you can bring any Descendant to the fight and weapons built around any attribute. But you still want to bring the top damage options because it’s the tankiest boss in the game.
The go-to Descendant for the Wall Crasher fight is Serena. She’s by far the strongest character for any content in The First Descendant—bring a fully built Serena with enough HP to maximize damage as well as Skill Cooldown and Skill Cost to maintain Redemption, and a built Ancient Knight or The Last Dagger to deal damage.
Other Descendants that appear in the Wall Crasher fight include Nell, Ines, Sharen, and even Yujin for more support and healing. But as long as you have a few Serenas, the Wall Crasher will fall extremely quickly.
