The first Destiny 2 raid, Leviathan, is meant to provide players with a significant challenge. Emperor Calus, the final boss, is meant to be a particularly tough adversary to beat, with many having to resort to guides on how to defeat him. But despite developer Bungie setting out to push players’ skills to the limit, one fireteam has shown that the developer may need to up the ante next time around.

In a video posted on YouTube, the six-person fireteam of Baxly, Cruelty It, Dark, Newin, Samiam1192, and Textbook1987 manage to take down the Leviathan raid’s final boss in just over four minutes. Technically, the team only needs about 30 seconds to beat Calus, but there are certain tasks to complete before he becomes vulnerable.

Using Celestial Nighthawk helmets and Golden Gun, as well as an Empowering Rift and an extremely high Force of Will buff, the Destiny 2 players are able to whittle the Emperor’s health bar down to nothing with little effort. Not only is this one of the quickest takedown’s of the boss so far, but the fireteam is also fairly sure that it’s the world’s first successful single plate Calus defeat as well. The boss battle usually takes teams multiple damage phases, with four damage plates in each phase.

The world’s first single damage plate Emperor Calus win follows several other world firsts for the Leviathan, including the world’s first four-person fireteam to successfully beat the raid. Bungie will surely be delighted (and maybe even a little bit surprised) that players have already come up with these genius strategies for completing the activity. While Destiny 2 players are tenacious, the Leviathan raid has been available for less than a week, making these world’s first achievements all the more impressive.

A lot of these quick raid completions come from hours of practice, where the team improves and tests strategies. But even so, Bungie may wonder whether the next Destiny 2 raid needs to be even harder.

Although players who aren’t so good at raids may struggle, more experienced teams like the one shown above will still need to be tested, and if they find the game’s content too easy, they may look elsewhere for a greater challenge. That’s a significant dilemma for Bungie, but for now, there are still a few world first’s left for players to obtain with the Leviathan raid.

Destiny 2 is out now for PS4 and Xbox One, and releases October 24 for PC.
