Warning! Black Myth: Wukong spoilers follow. If you’re playing through Black Myth: Wukong right now, you’ll be familiar with the action RPG’s boss fights. The game is packed full of them, and some offer a significant challenge.

But what if you could gain a helping hand from one boss as you fight another? That’s exactly what’s possible in Black Myth: Wukong via a super cool secret IGN unearthed while playing this week. It turns out that in Chapter Two, you can summon a hidden boss to defeat a required boss — if you find a bunch of items first. The boss fight in question is the Stone Vanguard , which is found in the Fright Cliff area.

You might have encountered this boss already, or even defeated it. But did you notice the large rock on the left as you entered the arena? That rock is in fact a dormant Shigandang Yaoguai King Boss , sealed away with six items of divinity, which you can use to release him. IGN has a guide, How to Defeat the Stone Vanguard With Another Boss , that will tell you all you need to know to summon Shigandang and have it do your dirty work for you.

What follows is a cool Black Myth Wukong Yaoguai King Boss Battle that you can sit back and admire from a safe distance. Eventually, Shigandang defeats the Stone Vanguard, although you then need to step in and defeat Shigandang yourself. Thankfully, the plucky Stone Vanguard took a bit of health off the much stronger Shigandang during the fight.

Check it out in the video below: It’s a pretty wild.
